Description

The claimed invention relates to the field of electric power, in particular to global automated systems that allow controlling the work of dissimilar objects of electric power at a substation level that are included in the power system and are located at a considerable distance from each other and from the power system operator.

The inventive automated system allows the power system operator, as a result of centralized processing and archiving of emergency oscillographic information at the upper hierarchical level of the power system, to obtain generalized and reliable information about the emergency processes recorded at all controlled electric power facilities of the substation level included in the power system, and also to determine the mutual influence of each other on other emergency processes occurring at various controlled electric power facilities rgetiki that led to the development of an emergency in the power system as a whole.

The main problem of attempts to create automated systems for recording, collecting, processing and storing emergency oscillographic information received from controlled facilities of a substation level included in the power system is the heterogeneity of controlled facilities, which is related to the different structure of a set of devices that are sources of emergency oscillographic information on the controlled ones objects and with different internal formats for the presentation of data on emergency oscillographic information ation received from emergency sources oscillographic information held on a specific test object.

The absence of automated systems for recording, collecting, processing and storing emergency oscillographic information makes the process of analyzing information about the emergency process by the energy system operator of the upper hierarchical level so complicated because of the huge amount of information received by the operator from emergency sources, which makes it almost impossible for the energy system operator to analyze the emergency process in the power system as a whole.

In real power systems, the controlled objects are electrical substations that are part of the power system, which are not homogeneous objects, since each substation has its own set of devices that can potentially be sources of emergency oscillographic information.

For example, in FIG. Figure 2 shows examples of structural diagrams of various controlled substations included in the power system, which have a different set of devices that could potentially be sources of emergency oscillographic information.

In particular, in FIG. Figure 2 shows the structural diagram of Substation 1, which is part of the power system, which is the 500 kV Tyumen substation actually operated since 2012 in Russia, which is part of the power system “MES (Backbone Electric Networks) of Western Siberia”, operating in the Tyumen region of Russia.

At Substation 1, a set of devices that could potentially be sources of emergency oscillographic information may include:

- alarm recording devices (RAS);

- microprocessor-based protection and automation devices (MPRZA);

- determinants of the place of damage to the power line (WMD);

- controller of connection to the power system (CRC);

- emergency automatic devices (PA).

A feature of the structural diagram of Substation 1 is that for the collection, processing and storage, and viewing of emergency oscillographic information by the operator of the substation level, Substation 1 is equipped with an automated process control system for the substation level (APCS of Substation 1).

In FIG. Figure 2 also gives an example of the structural diagram of Substation 2, which is part of the power system, which differs significantly from the structural diagram of Substation 1 in that the function of collecting, processing, storing and viewing emergency information by the operator of the substation level at Substation 2 is not carried out by ACS, but by other local substation level systems, for example, substation 2's own servers: the RAS server and the MPRZA server, which each operate in their own protocol and data format, therefore, Substation 1 and Substation 2 were not objects are homogeneous in structure.

An example of the structural diagram of Substation 2 is the 110 kV Bakhilovskaya substation, which is part of the Nizhnevartovsk electric networks energy system, which has actually existed and has been functioning since 2013 in the branch of OJSC Tyumenenergo.

Another example of implementing a block diagram of a substation is a block diagram of Substation n shown in FIG. 2. The structural diagram of Substation n differs from the structural diagrams of Substation 1 and Substation 2 in that there are no local systems for collecting, processing, storing and viewing emergency information at the substation level, and the collection, processing, storage and viewing of emergency information is assigned to a higher level of system control, namely, to the power system operator.

An example of the structural diagram of Substation n is the 220 kV Uzlovaya substation that has been operating in the territory of Russia since 2012 and is part of the Tyumen Distribution Networks energy system.

In really functioning power systems, there are a great many possible implementations of the layout of electrical substations included in the power system, the structural schemes of which were described above on the example of the structural schemes of Substation 1, Substation 2, (Substation n.

In addition, the heterogeneity of the controlled objects included in the power system is also determined by the fact that each of the RAS, MPRZA, OMP, KPR, PA devices collects its information using different data transfer protocols, for example, MODBUS, SPABUS, IEC 870-5- 103, IEC-61850 and has different interfaces, for example, RS-232, RS-485, RS-422, Ethernet. In this regard, there is a need to collect and store emergency oscillographic information received from these heterogeneous sources in a universal format to facilitate subsequent work with this archive for the purpose of viewing and further analysis by the power system operator.

However, even with the same protocols for transmitting data from devices of different manufacturers, there are features introduced by each manufacturer that differ from the standards, and therefore, when integrating these devices into the system, there is a need to bring the received alarm oscillographic information to a single format and now this single format is COMTRADE format. An alternative to the common COMTRADE format is the organization of its own data transfer format for the subsequent storage of this information in the global centralized archive of the power system at the top level of the hierarchy.

However, when creating automated systems for recording, collecting, processing, storing and viewing emergency oscillographic information by the operator, there is a problem associated with synchronizing the collected emergency information, both at the local substation level and at the inter-substation level of the regional power system operator. Synchronization of emergency oscillographic information collected from emergency sources of information, both from the local substation level and from the regional inter-substation level of the power system, is necessary to obtain an accurate retrospective picture of the entire emergency process occurring in the power system, with the aim of further analyzing the received emergency information with the involvement of automated means of processing this information.

In the absence of synchronization of emergency oscillographic information or its insufficiency, the overall emergency process in the power system is represented as a set of emergency information arrays coming from emergency information sources in the power system, which is not connected in any way or weakly connected with the time characteristics of the course and development of the emergency process, which leads to the fact that to analyze the array of collected emergency information, it is necessary to attract very highly qualified energy system operators m, but even the involvement of such specialists does not guarantee an absolutely correct assessment by the operator of the energy system of the ongoing emergency process both at the substation level and in the energy system as a whole, which in turn leads to subjective assessments and errors of the operator, the inability to correctly assess the ongoing and developing emergency process and take adequate measures to prevent and eliminate accidents in the power system.

In the current level of technology, developers have attempted to create multi-level hierarchical information models that would form the basis for the design of automated systems for recording, collecting, processing, storing and viewing information received from a controlled electric power facility (Journal of Electric Stations, No. 5, 2007, article authors Vishnyakova L.N., Kostenko V.V. et al. “Creation of a generalized information model and identification system for electric grid facilities”, pp. 55-60).

This article describes the possibility of creating automated systems for recording, collecting, processing, storing and viewing information received from various electric power facilities included in the RAO UES of Russia energy system based on CIM-models (CIM-Common Information Model).

The CIM model is a multi-level hierarchical structure that describes in a formalized form all the objects included in the power system from the lower substation level to the upper levels of the power system control hierarchy, and operating on the basis of a single unified basic standard for presenting information about the controlled objects included in the power system creating unified automated control systems for dissimilar objects of the electric power industry, regardless of technical, especially implementation of each specific object included in the power system.

The CIM model allows participants included in the power system and located at any level of the hierarchy to exchange any information necessary to control and manage energy facilities.

However, formalization using the CIM-model of the controlled object included in the power system is an important, but not the only task when creating automated control systems for electric power facilities.

However, the currently existing and functioning energy facilities that are part of the unified energy system in Russia do not have a unified description using the unified standard necessary for the implementation of the CIM model for the subsequent automation of the processing of information received in order to manage the energy system as a whole.

Nevertheless, at present, there is a very acute problem of creating automated energy management systems with a unified system of formalizing information about objects included in the energy system, and formalizing information about controlled parameters coming from electric power facilities.

Of particular relevance is the task of creating multi-level automated systems for recording, collecting, processing, storing and viewing emergency oscillographic information received from heterogeneous, remote-controlled controlled power generation facilities of a substation level included in a single power system at the workstation of an operator of a power system of the upper hierarchical level.

An automated system for collecting, processing and displaying information about a technological installation is known from the prior art, which is a complex integrated multi-level complex of electricity generating and distribution equipment, which has the ability to automatically monitor the normal operating condition of an object, as well as monitor and warn the system operator about the beginning and development accident at one or more facilities included in the power system (RF patent 2357278 for the invention "Creating warnings integrated process plant", the patentee: Fisher-Rosemount Systems, Inc., on the application №2004129311 / 09, filing date 28-02-2003, priority date 01.03.2002)..

In this automated system for collecting, processing and displaying information about a complex controlled object of the electric power industry, the controlled information received from field devices located at electric substations, which are heterogeneous objects located at the lowest levels of the hierarchy of the power system, is processed at the substation level and transmitted to the system operator at the top hierarchy level of the energy system in the form of generalized events characterizing the current state of objects included in the energy system STEM, in the normal, pre-emergency and emergency conditions.

A feature of this automated system is that the system operator, using the technical means of viewing the collected information, which is the automated workstation of the system operator, has the ability to isolate from the entire amount of information received that layer of emergency event information that is of interest to him.

Thus, this automated system is based on the collection and analysis of event information about the ongoing emergency process in the power system. In this case, the collected event information is ranked according to various severity levels based on predefined criteria. In this case, the ranking of event information is carried out according to three levels of severity from the point of view of the possible development of the emergency process: a message about the normal state of operation of the object, a warning message about the mismatch of the state of the object to the specified operating mode, and a message about the emergency state of the object.

However, such an automated system, based on the event assessment of emergency information, gives only an initial idea of the accident in the form of its generalized characteristics, which is an indirect representation of the emergency process by devices based on specified criteria, which does not allow to analyze the emergency process in its primary basis and the true causes of its occurrence .

A similar multi-level automated system for collecting, processing, storing and viewing emergency information in the power system, taking into account the specifics of managing Russian electric power facilities, is quite well presented in the article "Creating an automated system for the technological management of the functioning and operation of UNEG electric networks", authors A. Gelfand, Narovlyansky V.G., Fridman L.I. et al., JSC Institute Energosetproekt, published in the journal Electric Stations No. 5, 2007, pp. 13-23.

However, for a full assessment of the occurring emergency processes at the objects in the power system, it is necessary to use a system for recording alarm signals from the same primary sources of these signals, but in the form of oscillographic information, which is an array of data on analog and discrete signals, in the form of time slices with a resolution of 0.5 -2 ms, which form a retrospective picture in time about the beginning, development and completion of the emergency process in the power system, which allows the operator of the power system to himself to break down the emergency process and reliably evaluate it on a primary basis on its AWP, thus forming its own idea of the true causes of the emergency process.

Presentation of emergency processes in the form of a retrospective picture of time slices of the obtained oscillographic information with a resolution of 0.5-2 ms fully reflects the real emergency processes occurring in the power system with a duration of 20-1000 ms. And with the event nature of the emergency process assessment, the system operator is provided with information about only one time point of change in the state of the signal characterizing the emergency event, that is, the system operator deliberately receives a limited amount of information about the emergency process and cannot fully judge the actual occurring emergency processes in the power system .

The prior art knows about automated recorders of emergency events at power system facilities that use the alarm recording system in the form of oscillographic information from emergency information sources.

For example, the automated system NEVA, developed in Russia by the Scientific and Production Firm Energosoyuz, St. Petersburg, information about which has been available on the Internet since 2009 at www.energosoyuz.spb.ru, is known.

The NEVA automated system includes two subsystems, this is NEVA-TM, which monitors the parameters of the power system at the substation level, and the NEVA-RAS subsystem, which records alarms from a controlled object entering the power system.

The NEVA-RAS subsystem collects emergency oscillographic information from sources of such information located at the lower substation level. At the same lower substation level, there is a means of archiving the received emergency information in the form of information files in its own format or in the COMTRADE format, and the means of viewing the emergency information by the operator from the archive is implemented on the substation-level workstation. Thus, the NEVA-RAS system solves the problem of collecting, archiving and viewing emergency oscillographic information only at the substation level and is not intended for processing emergency oscillographic information and transmitting it to the system operator located at the upper hierarchical level of the power system. Nevertheless, it should be noted that the NEVA-RAS system has such an important tool as a means for synchronizing the received emergency information, implemented on the basis of a GPS system.

In a similar way, the system for collecting, archiving and viewing emergency information received from electric power facilities, developed by STC GOSAN and known as Black Box 2000, was implemented and operates, the information about which was published on the Internet at www.gosan.ru, and also the RAS Parma system developed by Parma LLC and published on the Internet at www.parma.spb.ru, and the RAS SHEE 23X system developed by NPP EKRA LLC and published on the Internet at www. ekra.ru

The article “Modern systems for the integrated automation of substations”, authors Asanbaev Yu.A., Gorelik TG, Filatov VG, OJSC NIIPT, published on October 16, 2011 at the Internet address www.rudocs, is also known in the art. exdat.com/docs/index-252920.html, which gave a general analysis of global trends in the development and construction of industrial control systems for the substation level based on a three-level hierarchical system of registration, collection, storage and viewing by the substation operator of information about steady and emergency operating modes of the substation.

The article describes in general terms one of the subsystems of a three-level hierarchical system, which discloses the processing of emergency oscillographic information received from heterogeneous sources of emergency oscillographic information at a substation level. The three-level hierarchical system for processing emergency oscillographic information received from heterogeneous sources at the substation level contains the first - lower hierarchical level, which contains the potential sources of emergency oscillographic information RAS, MPRZA, OMR, KPR, PA, and the second - the middle hierarchical level at which the conversion is performed emergency oscillographic information in a single data format and its transmission via local network communication channels to a server located on the third - ver its level in the hierarchy. At the third top level of the hierarchy are also AWPs of substation operators. The server of the third hierarchical level stores all retrospective information about all emergency processes that took place at one substation.

This article proposes to combine and archive individual waveforms on a substation-level server into a single alarm process based on a common time interval, which allows the substation-level operator to retrospectively view the alarm process as a whole, initially recorded as separate oscillograms received from various heterogeneous sources of emergency oscillographic information within the same substation.

The state of the art also knows modern complex hierarchical automated systems for collecting, processing, storing and viewing emergency oscillographic information coming from heterogeneous distributed sources located within the same controlled electric power facility at the substation level, included in the power system, for example, the article by Asanbaev Yu.A. ., Gorelik T.G. and others, OJSC “NIIPT”, “Hierarchical system for transmitting and viewing emergency information from heterogeneous distributed sources. The principles of construction and data processing algorithms ”, published in 2008 at the Internet address www.master.donntu.edu.ua.

This automated system was the first to implement the processing of emergency oscillographic information received from heterogeneous sources at a substation level. The processing of emergency oscillographic information in this system consists in converting the file structure containing retrospective information about the emergency process taking place in the power system, in which the emergency oscillographic information is presented as a single unit of information received simultaneously from all channels from each individual source of emergency information located on substation level, in the information block, which is information about the emergency process in the form of a single unit in deformations of containing information from all sources oscillographic emergency information, in particular emergency involved process in order to view it as a single process substation level emergency operator.

This information is stored in the database archive, located at the substation level, for the purpose of its further transmission and duplication via communication channels in automatic mode to a server located at a higher level of the power system hierarchy, for example, at the regional level of MES (Backbone Electric Networks), FGC (Federal Grid Company) in order to be able to view information on the emergency process as a whole occurring at one substation by a system operator located at the level of MES or FGC.

At the same time, this automated system has not yet resolved the issues of transmitting and processing emergency oscillographic information received from a variety of dissimilar substations that are a long distance from each other in the power system in order to store it at the upper hierarchical level of the power system and to ensure that it is possible a retrospective review and analysis by the operator of the energy system of the upper hierarchical level to create a generalized picture of the entire emergency process for the operator of the energy system, flowing in the power system as a whole.

The objective of the invention is the creation of an automated system for recording, collecting, processing, storing and viewing emergency oscillographic information received from a variety of heterogeneous, remote at a considerable distance from each other electric power facilities (substations) included in a single power system, with the aim of its storage on the upper hierarchical the level of the energy system and the possibility of its retrospective viewing and analysis by the operator of the energy system of the upper hierarchical level for the formation of he needs to present a generalized picture of the entire emergency process taking place in the power system as a whole, and the ability of the power system operator to evaluate the upper hierarchical level of the mutual influence of the individual components of the emergency processes taking place at various substations that are part of the power system, which led to the emergence and development of an emergency in the power system .

The problem is solved in that the automated system for registration, collection, processing, storage and viewing by the operator of the power system of emergency oscillographic information received from dissimilar controlled electric power facilities included in the power system contains at least one main controlled electric power facility of the substation level, including means registration and collection of emergency oscillographic information from heterogeneous sources of information of the main controlled object and electric power of substation level, means of synchronizing sources of emergency oscillographic information of the main controlled object of electric power industry, means of processing emergency oscillographic information at the substation level of the main controlled object of electric power, means of storing and archiving processed emergency oscillographic information at the substation level of the main controlled object of electric power, means for viewing the processed emergency Osci holographic information by the operator of the substation level of the main controlled electric power facility, means for transmitting processed emergency oscillographic information via communication channels from the main controlled electric power facility to the upper hierarchical level of the power system, means for storing and archiving emergency oscillographic information processed at the substation level of the controlled object at the upper hierarchical level of the power system electric power industry, automation this workstation (AWP) of the operator of the power system of the upper hierarchical level, made with the possibility of viewing emergency oscillographic information.

What's new is that the automated system contains at least one additional controlled facility of the substation-level electric power industry, including means for recording and collecting emergency oscillographic information from heterogeneous sources of information of the substation level of the additional controlled electric power facility, and means for synchronizing sources of emergency oscillographic information of the additional controlled electric power facility emergency oscillation processing facilities geographical information at the substation level of the additional controlled electric power facility, means for storing and archiving the processed emergency oscillographic information at the substation level of the additional controlled electric power facility, means for viewing processed emergency oscillographic information by the substation level operator at the additional controlled electric power facility, means for transmitting the processed emergency through communication channels oscilloscopes information from the additional controlled electric power facility of the substation level to the upper hierarchical level of the power system, the means of storing and archiving at the upper hierarchical level of the power system of emergency oscillographic information processed at the substation level from the main and additional controlled electric power facility, the means of centralized processing and archiving at the upper hierarchical level of the power system emergency oscilloscope information, semi from both the main and additional controlled objects of the electric power industry of the substation level included in the power system, including the means for centralized processing and archiving of file emergency oscillographic information, configured to generate a centralized file archive of emergency oscillographic information at the upper hierarchical level of the power system, and the means for centralized channel-by-channel processing and archiving alarm oscillographic information, perform with the possibility of forming at the upper hierarchical level of the power system a centralized per-channel archive of emergency oscillographic information processed at the top hierarchical level of the power system, while the centralized processing and archiving of file emergency oscillographic information performs centralized file processing by converting emergency oscillographic information received through communication channels from heterogeneous emergency oscillographic sources and formations, both from the main and from additional controlled power facilities of the substation level included in the power system, to the standard format used in the centralized file archive, and the centralized channel-by-channel processing and archiving tool performs channel-by-channel processing by extracting from the file emergency oscilloscope information stored in centralized file archive, information received on each channel separately from each heterogeneous emergency source The information obtained at both the main and additional controlled facilities of the electric power industry of the substation level included in the power system, and based on the assessment of the channel-processed emergency oscillographic information, determines the time interval during which the accident in the power system occurred, and the workstation (AWP) the operator of the power system of the upper hierarchical level is configured to view the operator of the power system emergency oscillographic information formations both from the centralized file archive and from the centralized channel-by-channel archive formed at the upper hierarchical level of the power system.

In the particular case of the invention, the automated workstation (AWP) of the operator of the power system of the upper hierarchical level can be additionally equipped with a means of generating a file user archive of a generalized view of accidents recorded by the operator of the power system, and is configured to view the operator of the power system of emergency oscillographic information from the file user archive of the generalized view about accidents recorded by the power system operator.

The inventive automated system for registration, collection, processing, storage and viewing by the energy system operator of emergency oscillographic information received from heterogeneous sources at a controlled electric power facility, contains several heterogeneous controlled electric power facilities of substation level (Substation 1, Substation 2 ... Substation n) included in the power system, in this case, each substation included in the power system may have a different set of devices that could potentially be a source of ikami emergency oscillographic information.

Each controlled electric power facility of the substation level contains a specific list of power equipment necessary for the operation of the electric substation, which must correspond to the required voltage classes: 500 kV (kilovolt), 330 kV, 220 kV, 110 kV, 35 kV, 10 kV.

In FIG. Figure 1 shows a schematic electrical diagram of the power equipment of a controlled power plant of a substation level included in the power system, while the figure shows one of the possible layouts of power electric equipment at a substation operating in three voltage classes. So, “Attachment 1” in FIG. 1 corresponds to a voltage class of 110 kV, “Connection 2” - to a class of 35 kV, “Connection n” - to a class of 10 kV.

Each voltage class corresponds to its own set of electrical equipment, combining equipment installed outdoors in the open areas of the substation: outdoor switchgears (outdoor switchgear), in particular 110 kV outdoor switchgear and 35 kV outdoor switchgear, or indoor switchgear (outdoor switchgear), in particular outdoor switchgear 10 kV, located indoors, which distribute energy between end users and operate with a voltage of class 10 kV.

The structure of open switchgears (outdoor switchgear 110 kV and outdoor switchgear 35 kV) includes switching devices: switches (Off) 1, disconnectors (P) 2, grounding knives (ZN) 3, power transformers (T) 4, as well as power measuring transformers current (TT) 5 and power measuring voltage transformers (VT) 6, connecting buses 7, power lines (VL) 8 operating on these voltage classes.

The enclosed switchgear (10 kV switchgear) includes roll-out bogies (Tel.) 9, grounding knives (ЗН) 3, switches (Off) 1, power measuring current transformers (ТТ) 5, power measuring voltage transformers (ТН) 6 , busbars 7 operating on this voltage class.

However, from the total composition of the power electrical equipment of the controlled substation-level electric power facility, it is necessary to control only a part of the status of the power electrical equipment of the substation and its main parameters characterizing the emergency oscillographic process, which include monitoring the status of all switches (Off) 1 and monitoring the current parameters and voltages in the secondary circuits of power measuring current transformers (CT) 5 and power measuring transformers voltage Nia (CN) 6.

The state of the circuit breakers (Off) 1 is controlled by two parameters: on / off, which corresponds to the control of discrete signals bearing a unified name - TV television signals.

Monitoring the current and voltage parameters in the secondary circuits of power measuring current transformers (CT) 5 and power measuring voltage transformers (VT) 6 give an idea of the possible occurring emergency processes at various points of the electrical substation circuit and are analog current and voltage signals, which have a unified name - signals (teleinformation) TI.

The secondary circuits of power measuring current transformers (CT) 5 and power measuring voltage transformers (VT) 6 are normalized current values of 1 A (ampere) and 5 A, and for voltage - 100 V (volt).

The primary circuits of power measuring current transformers (CT) 5 and power measuring voltage transformers (VT) 6 are selected depending on the voltage class for the selected part of the substation circuit or the load in the controlled part of the circuit for current.

For example, on a 110 kV outdoor switchgear, the primary circuit of a power voltage measuring transformer (VT) 6 should correspond to 110 kV, and in the secondary circuit of this measuring transformer, the voltage will correspond to a normalized value of 100 V.

The secondary circuits of power measuring current transformers (CT) 5 and power measuring voltage transformers (VT) 6 are galvanically isolated from the primary circuits of these transformers.

All signals received from the secondary circuits of the power equipment of the substation, namely, normalized analog signals of currents and voltages (TI) from the secondary circuits of the corresponding power measuring current transformers (CT) 5 and voltage (VT) 6, discrete signals of the state of the switches (Off) 1 - (TS), are assembled in crossing cabinets 10 and then fed to the input circuits of potential sources of emergency oscillographic information located at the lower hierarchical level of the substation (see Fig. 2, Substation 1): microprocessor-based troystv protection and automatics (MPRZA) 11, emergency automatic devices (PA) 12, device registration alarms (PAC) 13 places determinants transmission line fault (OMP) 14, controllers connection to the grid (DAC) 15.

In FIG. 2 is a structural diagram of the inventive automated system for recording, collecting, processing, storage and viewing by the operator of the power system of emergency oscillographic information received from heterogeneous controlled objects of the electric power industry that are part of the power system.

The power system includes three controlled electric power facilities of substation level: Substation 1, Substation 2 and Substation n, which are three dissimilar electric power facilities, remote from each other at a considerable distance.

Substation 1, Substation 2, and Substation n are dissimilar objects, because substations differ in electrical circuits, namely, the layout of power equipment and its connection diagram, various means for recording and collecting emergency oscillographic information, and various means for processing emergency oscillographic information on substation level, various means of storing and archiving processed emergency oscillographic information at the substation smoother, various means for viewing information processed oscillographic emergency operator substation level, various means for transmission over communication channels machined oscillographic emergency information from the substation to the upper hierarchical level of the power system.

Substation 1 in its structure is the most complex three-level controlled facility in the electric power industry.

At the lower hierarchical substation level, Substation 1, the so-called field level, there are means for recording and collecting alarm oscillographic information, which are: microprocessor-based protection and automation devices (MPRZA) 11, emergency automatic devices (PA) 12, and alarm recording devices (RAS) 13, locators of damage to the power line (OMP) 14, controllers connecting to the power system (CRC) 15.

Microprocessor-based protection and automation devices (MPRZA) 11 can be implemented on the basis of equipment manufactured in Russia by NPP EKRA or Mekhanotronika, for example: EKRA protection and automation of the B-110 BE2704v015UHL4 circuit breaker, EKRA Basic protection of overhead lines -110 kV BE2704v031UHL4, "EKRA" Backup protection of VL-110 kV BE2704v021UHL4, "EKRA" differential protection of tires (DZSh-110 kV) BE2704v061UHL4, "Mechanotronika" protection and automatic equipment V-35 kV BMR3-Vv-14, protection V-35 kV BMr3-Van-14 and automatic equipment SV-35 kV BMR3-SV-11, "Mechanotronika" line protection -10 kV BMR3-KL-11.

Anti-emergency automatic devices (PA) 12 can be implemented on the basis of equipment manufactured in Russia by NPP Dynamics or Prosoft-E CJSC, for example: NPP Dynamics AKA KEDR VL 110, Prosoft-E ZAO Microprocessor-based local emergency response automation 500 kV VL LUG MKPA-500 VLUG.

Alarm registration devices (RAS) 13 can be implemented on the basis of equipment manufactured in Russia by EnergoSoyuz, NEVA or NPP EKRA, for example: EnergoSoyuz, NEVA, DBK of the NEVA system, NPP EKRA Digital alarm recorder BEBE2704V900-042, "Prosoft-E" digital oscilloscope 110 kV RES-3.

The determinants of the place of damage to the power line (OMP) 14 can be implemented on the basis of equipment manufactured in Russia by “IC Bresler” device OMP VL-110 TOR-100 LOK 61 1302.

The power system connection controller (CRC) 15 can be implemented on the basis of equipment operated at energy facilities in Russia by Sprecher Automation or SATEC (Israel), for example: Sprecher Automation Multifunction controller SPRECON-EC SPRECON-EC G41, SATEC »Connection Controller SATEC-300.

The input circuits of precisely these devices through crossover cabinets 10 receive controlled analog signals (TI) from the secondary circuits of the power measuring power equipment (TT 5 and TN 6) and controlled discrete signals (TS) from the secondary circuits of the switches (Off) 1 through their block - contacts.

Devices (MPRZA) 11, (PA) 12, (PAC) 13, (OMP) 14, (KPR) 15 are multifunctional devices and are a standard set of well-known equipment currently operating at any electrical substation in Russia, for example, Bakhilovskaya substation in the branch of Tyumenenergo OJSC, which is part of the Nizhnevartovsk electric networks energy system, and each of these devices has a controller, RAM, analog-to-digital converters, and communication tools for exchanging information with rugim equipment in the substation.

All devices (MPRZA) 11, (PA) 12, (PAC) 13, (OMP) 14, (KPR) 15 have the function of oscillographing analog current and voltage signals, bearing a unified name - TI signals, and discrete state signals of switches 1, carrying unified name - vehicle signals, and can be potential sources of emergency information at an electrical substation.

By recording oscillographic information, we mean the formation of a continuous array of instantaneous values of analog (TI) and discrete signals (TS) received with a given sampling frequency from the sources of these signals in the device’s RAM (MPRZA) 11, (PA) 12, (RAS) 13, (OMP) 14, (CRC) 15. Typically, the frequency of polling signals (TI and TS) is strictly regulated and amounts to 1000-2000 Hz (Hertz), and the formation of continuous oscillographic information in the RAM of these devices is carried out on a ring basis.

The ring principle of recording oscillographic information means that when the RAM allocated to the array of oscillographic information in the indicated devices is completely filled, the subsequent slice of the oscillographic information is recorded in the RAM of these devices on top of the earlier recorded slice of this information, i.e., the previously recorded slice is erased slice information.

When registering an array of oscillographic information in the devices (MPRZA) 11, (PA) 12, (RAS) 13, (OMP) 14, (CRC) 15, the controllers of these devices continuously analyze the registered array of oscillographic information for signs of an emergency situation at the controlled object power, while the analysis is based on a set of accident criteria embedded in these devices.

When signs of an emergency are detected at the substation, the device controllers (MPRZA) 11, (PA) 12, (RAS) 13, (OMP) 14, (CRC) 15 proceed to the formation of an array of emergency oscillographic information, including sections of the oscillographic information obtained before the emergency process, during the development of the emergency process, after the end of the emergency process, and after a given allotted time for recording emergency oscillographic information, the process of generating an array of emergency oscillographic information is stopped Lebanon controllers of the same devices.

Based on the recorded and collected array of emergency oscillographic information, the controllers of each of the devices (MPRZA) 11, (PA) 12, (RAS) 13, (OMP) 14, (CRC) 15 form the file blocks of the emergency oscillographic information for their further storage and processing in own archive of each of the listed devices at the lower substation level for the purpose of their subsequent transfer to higher substation hierarchy levels, as well as to the upper hierarchical level of the power system for subsequent analysis by the operator ergosistemy.

The means for processing emergency oscillographic information at the substation level can have various implementation options, for example, at Substation 1, which is the main controlled object of the electric power industry, the means for processing emergency oscillographic information are distributed across three levels of the hierarchy.

The primary processing of emergency oscillographic information at the lower substation level is carried out with the formation of archive files in the own formats of each of the devices (MPRZA) 11, (PA) 12, (RAS) 13, (OMP) 14, (CRC) 15.

Archived alarm oscillation information files generated at the lower substation level at the request of the functional controller (FC) 16 of the middle substation hierarchical level are converted from the device's own format (MPRZA) 11, (PA) 12, (RAS) 13, (OMP) 14 into the generally accepted uniform format COMTRADE and / or the own format of the automated process control system, this is precisely what secondary processing of emergency oscillographic information consists of at the middle substation level of the hierarchy at Substation 1.

Further processing of the emergency oscillographic information is performed at the upper substation level of the hierarchy on the ACS TP 17 server.

The processing of emergency oscillographic information on the server of the automated process control system 17 at the upper substation level of the main controlled facility (Substation 1) consists in combining all the collected emergency oscillographic information on a specific accident recorded by devices (MPRZA) 11, (PA) 12, (RAS) 13, (ОМП) 14, (КПР) 15 at Substation 1, and its storage in the archive on the server of ACS TP 17 with the possibility of providing this information to the operator of the substation level for viewing it on the automated workstation of the operational service of substation 18, the automated workstation of relay service s of substation 19 and the workstation of automated process control system of substation 20. Thus, the server of automatic control system 17 performs the function of storing and archiving processed emergency oscillographic information at the substation level of the main controlled object, and the function of means for viewing processed emergency oscillographic information by the operator of the substation level of the main controlled object of the electric power industry (Substation 1) are performed by ARMs 18, 19, 20. The automated process control server can be implemented in the following configuration: redundant server - CPU - 2 Intel Xeon 3.2 GHz (two power supplies, a dual-processor system, 8 GB of RAM, a keyboard, a mouse-type manipulator, a 17 ”Samsung monitor, uninterruptible power supplies - UPS, surge protector). SCSI / SAS / SATA-drives are used as an information storage array, combined in a RAID 5/10 level with support for hot-swappable. Servers must be equipped with a duplicated Ethernet interface connected to various switches on the local network. As a server platform, an operating system of the level of Windows Server 2003 or higher is used.

Combining emergency oscillographic information on the server of the automated process control system 17 received from potential sources of emergency oscillographic information (MPRZA) 11, (PA) 12, (RAS) 13, (OMP) 14, (CRC) 15 at Substation 1 is possible only with synchronization facilities sources of emergency oscillographic information of the main controlled object of the electric power industry, built on GPS antennas 22 and the bus of the common time system (SEV) 23, to which all potential sources of emergency oscillographic information are connected at Substation 1. Decree These means of synchronizing emergency oscillographic information make it possible to create a general time-ordered retrospective picture of the entire emergency process occurring at Substation 1.

In addition, the control system server 17 has the ability to interrogate the controllers of the CRC 15 devices, which are a potential source of emergency oscillographic information, directly accessing them through local network communication equipment (LAN) 21 according to the standard GOSTR IEC 870-5-104 protocol, bypassing the functional controller (FC) 16.

The generated alarm oscillographic information file blocks are transferred to a higher substation level of the system hierarchy, as well as to the upper level of the power system hierarchy in automatic mode, however, the substation level operator has the ability to manually view each device from the archive (MPRZA) 11, (PA) 12, (PAC) 13, (OMP) 14, (CRC) 15 collected emergency oscillographic information.

The collected emergency oscillographic information from the substation level of Substation 1, namely, from the control system server 17 upon request from the server of the upper hierarchical level of the power system 24, using the means for transmitting through the communication channels the processed emergency oscillographic information from the main controlled facility of the electric power industry (Substation 1) is transmitted to upper hierarchical level of the power system for storing and archiving and subsequent centralized processing at the upper hierarchical level of the power system with using the server of the upper hierarchical level of the power system 24. Means for transmitting through the communication channels the processed emergency oscillographic information from the main controlled object of the electric power industry include: a device for communication at the substation 25 level and a communication device at the upper hierarchical level of the power system 26, connected by fiber optic communication channels 27 and / or radio-relay communication channels (RRL) 28, located at the middle level of the hierarchy of the power system.

The inventive automated system for recording, collecting, processing, storage and viewing by the energy system operator of emergency oscillographic information, contains additional electric power facilities of the substation level, namely, Substation 2 and Substation n, the structural diagrams of which are shown in FIG. 2.

As can be seen from the structural diagrams of these substations, they are significantly different from each other and are not homogeneous objects in structure.

So Substation 2 in its structure is a two-level controlled object of the electric power industry, in contrast to Substation 1, which is a three-level controlled object.

At the lower level of the hierarchy of Substation 2 there are potential sources of emergency oscillographic information: microprocessor-based protection and automation devices (MPRZA) 11 and emergency emergency devices (PA) 12, which are means for recording and collecting emergency oscillographic information from an additional controlled electric power facility at the substation level. Registration, collection and processing of emergency oscillographic information at the lower hierarchical level of Substation 2 is carried out in the same way as at the lower hierarchical level of Substation 1, after which emergency oscillographic information processed at the lower substation level is fed to the upper hierarchical level of the substation with the aim of its subsequent processing at this level.

The peculiarity of processing emergency oscillographic information at the upper hierarchical level of Substation 2 is that the function of processing, saving, archiving emergency oscillographic information is not performed on the ACS TP 17 server, as was the case on Substation 1, but on the servers of local systems: relay protection server and automation (RZA) 29 and the server of alarm registrars (RAS) 30, collecting information from devices of the same type, as a rule, from the same manufacturer MPRZA 11 and RAS 13 located on the lower hierarchical 2. Substations skom level PAC server 30 and server 29 are simultaneously RPA processing means, storing means and archiving treated oscillographic emergency information to the substation additional controlled electric power element.

The relay protection and automation server (RZA) 29 and the server of alarm recorders (PAC) 30 can be implemented on the basis of a conventional or industrial controller and run under the operating system level Windows XP SP3 PRO or higher.

Server (RZA) 29 and server (RAS) 30 must have a diverse and necessary set of input ports for connecting all heterogeneous sources of emergency oscillographic information at a specific substation.

At the upper hierarchical level (second level) of Substation 2, there is no integrated processing of emergency oscillographic information at the substation level, which took place on the server of the automated process control system 17 at Substation 1, and a combined archive of emergency oscillographic information received from all MPRZA 11 and RAS 13 devices is not formed from the lower hierarchical level of Substation 2.

Thus, the processing, storage and archiving of alarm oscillographic information at the upper hierarchical level is carried out separately for each equipment group, that is, on the relay server 29, only the processing, storage and archiving of alarm oscillographic information received from the MPRZA 11 devices from the lower level of Substation 2 occurs, and on the PAC 30 server, processing, saving and archiving of the emergency oscillographic information received only from the PAC 13 devices from the lower level of the Substation takes place 2.

The peculiarity of storing emergency oscillographic information at the upper level in Substation 2 is that the storage of emergency oscillographic information occurs only in the form of archives of files of its own or generally accepted COMTRADE format on the relay server RZA 29 and the server PAC 30, in contrast to Substation 1, on which, in addition to file saving alarm oscillographic information only in the COMTRADE format, the alarm oscillographic information is stored in the integrated database archive (DB) on the top hierarchical skom level server PCS 17 Substations 1.

The second distinctive feature in the structure of Substation 2 is that the means for viewing processed emergency oscillographic information by the substation level operator at an additional controlled electric power facility are made in the form of RPA 31 AWPs and PAC 32 AWPs, each of which provides the substation level operator with the possibility to view emergency oscillographic information archives received from the corresponding devices of the same type, that is, at the RPA 31 automated workstation, the substation level operator of substation 2 has the ability to view emergency oscillographic information received only from MPRZA 11 devices of substation 2, and on the ARM RAS 32 the substation level operator of substation 2 is able to view emergency oscillographic information received only from the RAS 13 devices of substation 2.

However, to view the operator of the substation level of Substation 2 of emergency oscillographic information even at the local level of Substation 2, synchronization sources of emergency oscillographic information of an additional controlled electric power facility are needed, built on GPS antennas 22 and the bus of the time system 23, to which the relay and relay protection server 29 and the server are connected PAC 30 Substation 2.

The peculiarity of Substation 2 is that the means for synchronizing sources of emergency oscillographic information of an additional controlled facility in the electric power industry, built on GPS antennas 22 and the bus of the single time system 23, are located on the upper hierarchical substation level and RZA 29 servers and RAS 30 server of Substation 2 are connected to them, unlike Substation 1, on which the means for synchronizing the sources of emergency oscillographic information of the main controlled object of the electric power industry are built on GPS antennas 22 and a single time system 23 bus, are located on the middle hierarchical substation level and the functional controller FC 16 and the connection controller CRC 15 are connected to them. Organization of synchronization of emergency oscillographic information at Substation 2 is necessary for the subsequent centralized processing of emergency oscillographic information received from Substations 2 and Substations 1 on the server of the upper hierarchical level of the power system 24.

Thus, the operator of the substation level of Substation 2 does not have the opportunity to get a generalized picture of the emergency process taking place in Substation 2 due to the lack of the integrated processing of emergency oscillographic information from all potential sources of emergency oscillographic information available in Substation 2 at the substation level of Substation 2.

The collected emergency oscillographic information from the substation level of the additional controlled electric power facility of Substation 2, namely, the relay protection and automation server 29 and the RAS 30 server, upon request from the server of the upper hierarchical level of the power system 24 using the means for transmitting processed emergency oscillographic information from the additional controlled object via communication channels Power substation 2 is transferred to the upper hierarchical level of the power system for storage and archiving and subsequently centralized processing at the upper hierarchical level of the power system using the server of the upper hierarchical level of the power system 24.

Means for transmitting through the communication channels the processed emergency oscillographic information from the additional controlled facility of Substation 2 are similar to the same communication facilities 25, 27 and 28 that are used to transmit emergency oscillographic information from the main controlled facility of the electric power industry - Substation 1, and the communication facility is the communication device the upper hierarchical level of power system 26 is common to Substation 1 and Substation 2.

However, in real power systems, as another additional controlled object of the electric power industry, a substation having only one hierarchical level in its structure can be included. An example of such an additional controlled electric power facility is Substation n, the structural diagram of which is shown in FIG. 2.

At Substation n, there is only one lower (field) substation level at which potential sources of emergency oscillographic information MPRZA 11 and PAC 13 are located.

Means of registration and collection of emergency oscillographic information at Substation n are implemented on MPRZA 11 and RAS 13 devices, and processing, storage and archiving of emergency oscillographic information at Substation n is carried out directly on the MPRZA 11 and RAS 13 devices themselves, on which file archives of emergency oscillographic information are generated substation level, presented in the proprietary system format or in the generally accepted COMTRADE format. In the absence of operator AWS at substation level at Substation n, personal computers (laptops) of substation n operator with RS-232, RS-485 interfaces can act as means for viewing the substation level operator of the processed alarm oscillographic information at the lower hierarchical substation level of Substation n RS-422.

Collected emergency oscillographic information from the substation level of an additional controlled electric power facility of Substation n, namely, from MPRZA 11 and PAC 13 devices, upon request from the server of the upper hierarchical level of power system 24 using means for transmitting processed emergency oscillographic information via additional communication channels from an additional controlled electric power facility Substation n is transferred to the upper hierarchical level of the power system for storage and archiving and subsequent neutralized processing at the upper hierarchical level of the power system using the server of the upper hierarchical level of the power system 24.

Means for transmitting through the communication channels the processed emergency oscillographic information from the additional controlled facility of Substation n are similar to the same communication facilities 25, 27 and 28 that are used to transmit emergency oscillographic information from the main controlled facility of the electric power industry - Substation 1, and the communication facility is a communication device the upper hierarchical level of power system 26 is common to Substation 1, Substation 2 and Substation n.

The peculiarity of Substation n is that the means for synchronizing emergency oscillographic information sources at Substation n, built on GPS antennas 22 and the bus of the single time system 23, are directly connected to potential sources of emergency oscillographic information located at the lower substation level of Substation n, MPRZA 11 and PAC 13, having input circuits for connecting synchronization tools.

The organization of synchronization of emergency oscillographic information at Substation n is necessary for the subsequent centralized processing of emergency oscillographic information received from Substation n, Substation 2 and Substation 1 on the server of the upper hierarchical level of power system 24.

The function of means of storing and archiving at the upper hierarchical level of the power system of the emergency oscillographic information processed at the substation level of both the main and additional controlled objects of the electric power industry is performed by the server of the upper hierarchical level of the power system 24.

The server of the upper hierarchical level of the power system 24 is also a means of centralized processing at the upper hierarchical level of the power system of emergency oscillographic information received from both the main and additional controlled power facilities of the substation level included in the power system, made with the possibility of separate centralized processing of file emergency oscillographic information and the formation of at the top hierarchical level of the power system centrally a file archive and centralized processing per channel oscillographic emergency information and the formation of the upper hierarchical level of the power system of centralized backup by channel oscillographic emergency information.

To create a centralized file archive, blocks of file alarm oscillographic information are provided from Substation 1, Substation 2 ... Substation n, included in the power system, to the server of the upper hierarchical level of power system 24 either in the standard COMTRADE format or in its own format.

When transferring blocks of file emergency oscillographic information in the COMTRADE format to the upper hierarchical level of the power system from a specific source of emergency oscillographic information located at the substation level, the block of file emergency oscillographic information for the controlled object of the electric power industry is presented in the form of two required files containing:

- a separate file with the current values of the controlled parameters of power equipment at a specific controlled facility of the electric power industry (substation);

- a separate file with information about the structure of the most controlled object of the electric power industry (substation),

or in the form of three files containing both the required files mentioned above and a file with additional information on the generalized characteristic of the emergency event recorded on a specific controlled object (substation), which is stored and generated by the controllers of potential sources of emergency oscillographic information of the lower substation level: (MPRZA) 11, (PA) 12, (PAC) 13, (OMP) 14, (CRC) 15. The third file can be used by the power system operator only to manually view information about the emergency process.

Thus, on the server of the upper hierarchical level of the power system 24, a centralized file archive of emergency oscillographic information is automatically generated, which is a collection of all archive files of emergency oscillographic information received from the main and additional controlled objects of the electric power industry included in the power system (Substation 1, Substation 2 ... Substation n) on which the emergency process was recorded.

The operator of the power system of the upper hierarchical level already at this stage of processing emergency oscillographic information can view the operator of the power system 33 of the upper hierarchical level, the centralized file archive of the emergency oscillographic information generated on server 24. Moreover, the operator of the system can only view the centralized file archive individually from each source of emergency oscillographic information located on any of the Tanzi (substations 1, 2 ... substations substations n), within the grid.

However, for a comprehensive analysis of the emergency process occurring in the power system, the operator of the upper hierarchical level of the power system must simultaneously view information on a variety of emergency oscillographic information sources located at different substations included in the power system.

Currently available in the prior art means of viewing file archives of emergency oscillographic information in COMTRADE format on the workstation of the operator of the upper hierarchical level energy systems supplied by various manufacturers do not allow him to view simultaneously information on all sources of emergency oscillographic information located at various substations included in the power system , therefore, the operator of the power system to create a comprehensive understanding of the emergency process in power systems You do not have to sequentially view and analyze manually all the files of emergency oscillographic information that came from all sources of emergency oscillographic information to the upper hierarchical level of the power system from the substation level.

With the increase in the number of monitored substations included in the power system, the process of analyzing file emergency oscillographic information by the operator of the power system is becoming more complicated due to the huge array of file emergency information that he needs to analyze. In addition, the time of analysis and assessment by the operator of the energy system of the entire ongoing emergency process is significantly increased.

Another significant factor affecting the time of analysis and assessment of the emergency process recorded in the power system is the level of qualification of the power system operator, however, even very qualified and experienced power system operators will not be able to cope with such a volume of emergency oscillographic information and meet the regulatory deadlines established by operational regulations for deciding on a specific accident recorded in the power system. Therefore, for a comprehensive assessment of the entire emergency process, it is necessary to use automated means for centralized processing of emergency oscillographic information at the upper hierarchical level of the power system.

To achieve this goal, in order to form a comprehensive view of the operator of the power system about the emergency process occurring in the power system as a whole, which was recorded in the power system using local means of oscillography of the emergency process at the substation level, centralized processing of the emergency oscilloscope is performed on the server 24 of the upper hierarchical level of the power system information, including separate centralized processing of file emergency oscillographic information and with the creation of a centralized file archive, by converting emergency oscillographic information received through communication channels from heterogeneous sources of emergency oscillographic information, both from the main and from additional controlled electric power facilities of the substation level included in the power system, into the standard format used in the centralized file archive and centralized channel-by-channel processing of emergency oscillographic information with the formation of centralized of the channel-by-channel archive by extracting from the emergency alarm oscillographic file information stored in the centralized archive, information received on each channel separately from each heterogeneous emergency oscillographic information source installed at both the main and additional controlled substation-level electric power facilities included in power system.

In FIG. 3 shows a functional diagram of the inventive automated system with a detailed disclosure of the functional diagram of the server of the upper hierarchical level of the power system 24.

As can be seen from FIG. 3 on the server of the upper hierarchical level of the power system 24 are located: a means of storing and archiving at the upper hierarchical level of the power system of the emergency oscillographic information processed at the substation level from the main and additional controlled objects (Substation 1, Substation 2 ... Substation n) 34, the means of centralized processing and archiving the upper hierarchical level of the power system 35, including a means for centralized processing and archiving file emergency oscilloscope information 36, adapted for forming on the upper hierarchical level grid centralized file archive oscillographic emergency information 37 and means for centralized processing and archiving per channel alarm information oscillographic 38, adapted for forming on the upper hierarchical level per channel centralized archive information oscillographic emergency power system 39.

At the same time, the centralized processing and archiving tool for file emergency oscillographic information 36 performs centralized file processing by converting emergency oscillographic information received through communication channels from heterogeneous sources of emergency oscillographic information (MPRZA) 11, (PA) 12, (RAS) 13, (OMP) 14, (CRC) 15, both from the main (Substation 1) 40, and from the additional (Substation 2 ... Substation n) 41, 42 monitored power facilities of the substation level included in the power by the way, to the standard COMTRADE format used in the centralized file archive 37. Emergency oscillographic information coming from substations 40, 41, 42 located at the lower hierarchical level of the power system is synchronized by means of synchronizing emergency oscillographic information sources 43 built on GPS antennas 22 and the system bus United Time (SEB) 23.

The means for centralized channel-by-channel processing and archiving of emergency oscillographic information 38 performs channel-by-channel processing by extracting from the emergency alarm oscillographic file information stored in the centralized file archive 39, information received on each channel separately from each heterogeneous emergency oscillographic information source (MPRZA) 11, (PA) 12, (PAC) 13, (OMP) 14, (CRC) 15, installed both at the main 40 and at the additional controlled facilities 41, 42 of the electric power industry under tantsionnogo level within the grid.

The automated workstation (AWP) of the operator of the power system of the upper hierarchical level 33 is configured to view the operator of the power system of emergency oscillographic information both from the centralized file archive 37 and from the centralized channel-by-channel archive 39 formed at the upper hierarchical level of the power system.

In addition, in particular cases of the invention, the automated workstation (AWP) of the operator of the power system of the upper hierarchical level 33 can be additionally equipped with a means of forming, at the upper hierarchical level of the power system, a file user archive of a generalized view of accidents 44 recorded by the power system operator. The tool for generating a file of user accident archives 44 at the upper hierarchical level of the power system can be implemented on the basis of a personal computer of industrial or office design, as well as a laptop operating under Windows 7 or higher operating systems included in the workstation of the power system operator.

The tool for generating, at the top hierarchical level of the power system, a file user archive of a generalized view of accidents 44 recorded by the power system operator, allows the power system operator to create his own personal archive of accidents that occurred in the power system by selecting from the centralized channel-by-channel archive of alarm oscillographic information 39 most relevant for accident system operator, while the accident archive can be generated in the car’s own format atizirovannoy system.

The operation of the claimed automated system is illustrated by the algorithm of the server of the upper hierarchical level of the power system 24, which includes the algorithm of the means for storing and archiving at the upper hierarchical level of the power system of the emergency oscillographic information processed at the substation level from the main and additional controlled objects (Substation 1, Substation 2 ... Substation n ) 34 shown in FIG. 4 “a”, the algorithm of the centralized processing means of the upper hierarchical level of the power system 35, consisting of the algorithm of the centralized processing and archiving means of the file emergency oscillographic information 36 shown in FIG. 4 “b”, and the algorithm of operation of the means of centralized channel-by-channel processing and archiving of emergency oscillographic information 38 shown in FIG. 4 “c”, as well as channel-by-channel oscillograms of emergency processes recorded at controlled electric power facilities included in the power system shown in FIG. 5 and the screen forms shown in FIG. 6 “a” and FIG. 6 b, FIG. 6 "c", FIG. 7 a and FIG. 7 “b”, which display on the operator’s automated workstation operator of the upper hierarchical level 33 emergency processes that occurred in the power system, recorded from two sources of emergency oscillographic information PAC 13 (1) and PAC 13 (2) on the main and from one source of emergency oscillographic information PAC 13 (1) at additional controlled electric power facilities of substation level included in the power system.

The server of the upper hierarchical level of the power system 24 continuously scans for the presence of alarm oscillographic information arriving at the upper hierarchical level of the power system from the main monitored electric power plant 40 (Substation 1), this function is implemented in block 45 of the algorithm, as well as from the additional controlled electric power object 41 (Substation 2) with the implementation of this function in block 46 of the specified algorithm and an additional controlled object of the electric power industry 42 (Substation n) with the implementation this function in block 47 of the algorithm.

When determining the availability of emergency oscillographic information from its sources located in Substation 1, the process of its transmission to the upper hierarchical level of the power system with the implementation of this function by block 48 is activated.

When determining the availability of emergency oscillographic information from its sources located in Substation 2, the process of its transmission to the upper hierarchical level of the power system with the implementation of this function by block 49 is activated.

When determining the availability of emergency oscillographic information from its sources located at Substation n, the process of its transmission to the upper hierarchical level of the power system with the implementation of this function by block 50 is activated.

Using the function implemented in block 51, a temporary file archive of emergency oscillographic information obtained from the substation level from controlled electric power facilities 40, 41, 42 is generated at the upper hierarchical level. This archive is temporary and serves as a source of emergency oscillographic information for the subsequent formation of a centralized file archive of emergency oscillographic information 37 and a centralized channel-by-channel archive of emergency oscillographic information 39 to the top hierarchical level of the power system.

The temporary file of alarm oscillographic information archive, implemented in block 51, is intermediate, since it is created and exists only for the period of subsequent centralized processing of alarm oscillographic information with the formation of a centralized file and centralized channel-by-channel archives of emergency oscillographic information, and upon completion of the formation of these centralized archives, emergency oscillographic information stored in a temporary file archive on the top hier hicheskom level grid destroyed by its erasure.

According to the algorithm shown in FIG. 4 “a”, the process of storing and archiving alarm oscillographic information in a temporary file archive at the upper hierarchical level, coming from the main controlled electric power facility 40 and additional controlled electric power facilities 41 and 42, is carried out continuously and cyclically with the implementation of this function in block 52 of the algorithm until until all sources of emergency oscillographic information at all controlled electric power facilities 40, 41, 42 in the power system are polled by server 24.

If the process of interrogation of controlled electric power facilities 40, 41, 42 in the power system is not yet completed, then algorithm block 52 instructs the block 54 of the algorithm to continue the process of interrogating emergency oscillographic information sources from other subsequent controlled electric power facilities included in the power system.

If all controlled objects of the electric power industry in the power system are interviewed, the algorithm block 52 transfers control to the block 55 of the centralized processing tool for file emergency oscillographic information 36 for subsequent centralized information processing with the formation of a centralized file archive.

If block 53 noted the absence of emergency oscillographic information as a result of interrogation of all controlled objects of the electric power industry, then control returns to block 45 of the algorithm.

If block 53 detected the presence of emergency oscillographic information as a result of interrogation of all controlled electric power facilities at least one controlled electric power facility, then control is transferred to block 55 of the algorithm for centralized processing and archiving of file emergency oscillographic information 36 for subsequent centralized processing of information with the formation of a centralized file archive.

The algorithm of operation of the centralized processing and archiving means at the upper hierarchical level of the power system of emergency oscillographic information received from both the main and additional controlled power facilities of the substation level included in the power system is shown in FIG. 4 b and FIG. 4 "in".

In FIG. 4 “b” shows the algorithm of the means of centralized processing and archiving at the upper hierarchical level of the power system of file emergency oscillographic information.

Having received control from the block 52 of the algorithm, the block 55 of the algorithm selects the next file of emergency oscillographic information from the temporary file archive of the emergency oscillographic information 51, formed at the top hierarchical level, and analyzes the format of the selected file for its compliance with the standard COMTRADE format. This function is implemented in algorithm block 56.

If the format of the selected alarm oscillographic information file conforms to the standard COMTRADE format, then it is stored in the centralized file of the alarm oscillographic information archive 37. The centralized file archive of the alarm oscillographic information is generated at the upper hierarchical level of the power system by block 58 of the algorithm.

If the algorithm block 56 determines that the selected alarm oscillographic information file has its own format, that is, does not correspond to the standard COMTRADE format, then the algorithm block 57 converts the selected alarm oscillographic information file from an arbitrary format to the standard COMTRADE format. This function is implemented by block 57 of the algorithm.

The selected alarm oscillographic information file, converted to the standard COMTRADE format, is placed in a centralized file archive of alarm oscillographic information 37. This function is implemented by block 58 of the algorithm.

The block 59 of the algorithm controls whether all selected files from the temporary file archive of the alarm oscillographic information 51 are processed. If all the selected files from the temporary file archive of emergency oscillographic information 51 are processed, this means that the process of generating a centralized file archive at the upper hierarchical level of the power system for this emergency process is completed, and you can transfer control to block 60 of the algorithm for subsequent centralized channel-by-channel processing of emergency oscillographic information at the top hierarchical level.

If all files from the temporary file of the alarm oscilloscope information 51 have not yet been processed, then block 59 returns control to block 55 to continue the process of selecting the next file from the temporary file of the alarm oscilloscope information 51.

Figure 4 "c" shows the algorithm of the means of centralized channel-by-channel processing and archiving of emergency oscillographic information at the upper hierarchical level of the power system.

Having received control from the block 59 of the algorithm, the block of algorithm 60 selects a file from a centralized file archive of emergency oscillographic information 58 for its further centralized channel-by-channel processing at the upper hierarchical level of the power system.

The centralized channel-by-channel processing of the selected file from the centralized file archive of emergency oscillographic information 58 through one of the selected channels is carried out in two stages.

In block 61 of the algorithm, centralized channel-by-channel processing of the selected file is carried out by converting the file information into a data array through one of the selected channels of one source of emergency oscillographic information located on one of the monitored objects included in the power system.

In the inventive automated system, each controlled substation-level electric power facility included in the power system has a strictly formalized structure of the entire facility, including power equipment, sources of emergency oscillographic information, including a description of all the characteristics of the controlled channels of these sources of emergency oscillographic information, including their characteristics input circuits, presented in the form of a single database stored on the server of the upper hierarchical level 24.

Thus, each data array in one of the selected channels generated by the algorithm block 61 will unambiguously correspond to the information contained in a single database stored on the server 24, created at the design stage of the inventive automated system, about the corresponding selected channel with the presentation of its main characteristics , belonging to the corresponding source of emergency oscillographic information installed at a specific controlled facility of the electric power industry, included in power system.

At the second stage of centralized channel-by-channel processing by block 62 of the algorithm, the time interval ΔT = Tcon is determined based on information in the data array received in block of algorithm 61. (end time of the emergency process) - Tnach. (time of the beginning of the emergency process) during which the emergency process was recorded on the selected channel.

In the next block of algorithm 63, the time interval ΔT determined by the block of algorithm 62 for a particular channel is compared with the time intervals ΔT of previously recorded emergency processes in the power system.

If for the time interval ΔT identified by block 62 the block of algorithm 63 does not find a correspondence with the time intervals ΔT of previously recorded emergency processes in the power system, then block 64 of the algorithm proceeds to generate 39 signs of a new accident in the power system in the centralized channel archive of alarm oscillographic information with assignment of N - ordinal accident numbers and timestamps of its beginning - Tnach. and its endings - Tkon. or a sign of expanding the time interval of a previously recorded accident, which will be further used in block 65 of the algorithm to identify the emergency process recorded on a particular channel.

If the block 63 of the algorithm establishes the correspondence of the time interval determined by the block 62 of the algorithm to the time interval ∆T of any one of the previously recorded emergency processes in the power system, block 65 of the algorithm proceeds to generate in the centralized channel-by-channel archive of alarm oscillographic information 39 the archive of the specific emergency process recorded in block 61 of the algorithm in the form of an array of data, with the assignment of the serial number of the accident, fixing the time interval during which iksirovan this emergency process on the selected channel from a particular source oscillographic emergency information, set in a specific controlled object electricity, part of the grid.

Next, the block 66 of the algorithm determines whether all the channels selected by the block 60 of the algorithm file are centrally processed channel-by-channel.

If not all channels have undergone processing, then there is a return to block 61 of the algorithm for centralized processing of the next channel.

If all the channels for the file selected by the block 60 are processed, then the algorithm block 67 destroys the source file from the temporary file archive of emergency oscillographic information at the upper hierarchical level of the power system 51 corresponding to the selected file from the centralized file archive 37 already used for centralized channel processing.

Next, block 68 of the algorithm determines whether all selected files from the centralized file archive of alarm oscillographic information 37 are processed.

If not, then the algorithm block 68 transfers control to the algorithm block 60, and the algorithm block 60 selects the next file from the centralized file archive of alarm oscillographic information 58 for centralized channel-by-channel processing.

If it is established that all the selected files from the centralized file archive of the alarm oscillographic information are processed, then the block 68 of the algorithm transfers control to the block 45 of the algorithm to resume the cycle of determining the next emergency process in the power system.

A generalized idea of the emergency process occurring in the power system is formed by the server 24 at the upper hierarchical level of the power system based on the analysis by the same server of the results of centralized channel-by-channel processing of information received from each channel from all sources of emergency oscillographic information located at all controlled electric power facilities of the substation level, included in the power system.

In FIG. 5 is a timing diagram that illustrates the process of forming a generalized representation using two emergency processes recorded in the power system as an example.

As can be seen from the diagram shown in FIG. 5, a generalized representation of the accident №1, fixed in the power system, has been formed on the basis of the analysis of 24 emergency oscillographic server information obtained through three channels from different sources oscillographic emergency information at different controlled power generation facilities (Waveform 1 ^th channel Waveform 2 ^th channel oscillogram ^th channel 3).

Server 24, receiving information on the first channel from the first source of emergency oscillographic information located at the main controlled facility of the electric power industry, for example, Substation 1, determines the time ΔT ₁ = Tkon. ₁ - Init. ₁ , during which the first emergency process was recorded in the power system, which was assigned the serial number of the accident - Alarm No. 1, while server 24 writes the duration of Alarm No. 1 to the centralized channel archive in block 64 of the algorithm, equal to the duration of the emergency process ΔТ ₁ , defined on channel 1.

Then, server 24 begins to receive information about the presence of an emergency process on the second channel from another source of emergency oscillographic information located at another controlled electric power facility, for example, Substation 2 with the time parameters of the fixed emergency process ΔТ ₂ = Ткон. ₂ - Init. ₂ , different from the time parameters of the emergency process recorded on the first channel. Moreover, as can be seen from the diagram in FIG. 5, the time intervals ΔT ₁ and ΔT ₂ overlap, as a result of which the server 24 makes a decision to expand the boundaries of the time interval of Alarm No. 1 by the limit values of the start time and end time of the emergency processes recorded on the first channel and second channel, i.e. the interval of Alarm No. 1 expands and is now defined as the start time of Alarm No. 1, equal to Tnach. ₁ on the first channel, and the end time of Accident No. 1, equal to Tkon. ₂ on the second channel.

Further, as can be seen from the diagram shown in FIG. 5, the time interval ΔТ _{3 of} emergency oscillographic information received on the third channel from the third source of emergency oscillographic information located at the third controlled facility of the electric power industry, for example, Substation n, does not overlap two time intervals ΔТ ₁ and ΔТ ₂ from the previous emergency processes recorded earlier on the first channel and on the second channel, while ΔТ ₃ and ΔТ _{2 there} was a temporary pause, the duration of which was less than a predetermined set time ΔTpause. ₁ ≤ 3 sec., Characterized by the absence of any alarm oscillographic information. With a pause duration of less than 3 seconds, server 24 decides to enable the emergency process recorded on channel 3 as a component that characterizes Alarm No. 1 and the next extension of the time interval of Alarm No. 1, the start time of which will now be determined as Tnach. ₁ on the first channel, and the end time is like Tkon. ₃ on the third channel.

Further, as can be seen from the diagram shown in FIG. 5, the server 24 proceeds to process the emergency oscillographic information coming in on the fourth channel from the source of the emergency oscillographic information located, for example, at Substation 2. The time interval of the emergency process recorded on the fourth channel is ΔТ ₄ = Tkon. ₄ - Init. ₄ . As can be seen from the diagram, there is a temporary pause between the emergency processes recorded on the third channel and the fourth channel, which is more than 3 seconds established by the system, therefore this information is regarded by the server 24 as information that cannot be attributed to Alarm No. 1, in connection with which, server 24 proceeds to the formation of a new accident in the power system with the assignment of the following serial number - Alarm No. 2. The time interval of Alarm No. 2 at this stage of processing will be characterized by the start time of Alarm No. 2 equal to Tnach. ₄ , and the time of the end of the accident number 2 equal Tkon. ₄ .

Further, as can be seen from the diagram shown in FIG. 5, the server 24 proceeds with the processing of emergency oscillographic information coming in from the fifth channel from the source of emergency oscillographic information located, for example, at Substation 1. The time interval of the emergency process recorded through the fifth channel is ΔТ ₅ = Tkon. ₅ - Init. _5. As can be seen from the diagram, there is a temporary pause between the emergency processes recorded on the third channel and the fifth channel, which is more than 3 seconds, set by the system, therefore this information is regarded by server 24 as information that can be attributed to Alarm No. 2. However, as can be seen from the diagram, the time intervals ΔТ ₄ and ΔТ ₅ characterizing respectively recorded emergency processes on the fourth and fifth channels overlap each other, so server 24 decides to include the detected emergency process on channel 5 as component of Alarm No. 2 in power system. At the same time, server 24 makes a decision to expand the boundaries of the time interval of Alarm No. 2 to the boundaries of the beginning of the emergency process on the fifth channel, that is, the time interval of Alarm No. 2 expands and is now defined as the start time of Alarm No. 2, equal to Tnach. ₅ on the fifth channel, and the end time of Accident No. 2, equal to Tkon. ₄ on the fourth channel.

In FIG. 6 "a", FIG. 6 b, FIG. 6 "c", FIG. 7 “a”, FIG. 7 “b” shows graphical screen forms of the emergency process recorded at two controlled electric power facilities included in the power system, namely, at Substation 1 and Substation 2 from three sources of emergency oscillographic information: PAC 13 (1) at Substation 1, PAC 13 (2) at Substation 1 and PAC 13 (1) at Substation 2, which are displayed on the automated workstation (AWS) of the operator of the power system of the upper hierarchical level.

Moreover, in FIG. 6 "a", FIG. 6 b, FIG. 6 “c” displays the information received by the power system operator from the centralized file archive sequentially for each emergency oscillographic information source separately, and in FIG. 7 “a”, FIG. 7 “b” displays the information received by the power system operator from the centralized channel-by-channel archive, presented in separate frames for each indicated source of emergency oscillographic information in one screen form.

In FIG. 6 “a” is a graphical screen representation of the emergency process on the automated workstation of the operator of the upper hierarchical level 33, obtained by the operator when accessing the centralized file archive 37 from the first source of emergency oscillographic information PAC 13 (1) located at Substation 1.

As seen in FIG. 6 “a” on frame 1 during the time period marked by a temporary marker, the first source of alarm oscillographic information PAC 13 (1) in Substation 1 in the power system was a surge in phase A voltage and phase B on VT 6 - 110 kV on the bus 7 first tire system. In addition, at Substation 1 at PAC 13 (1) on VT 6 - 110 kV on bus 7 of the first bus system, a zero-sequence voltage surge was detected at the same time, which allowed the power system operator to evaluate this information as a sign of an emergency process recorded at Substation 1, at the indicated source.

At the same time, the power system operator, when viewing file information from a centralized file archive 37 from the second source of emergency oscillographic information PAC 13 (2) at Substation 1 (Fig. 6 “b”), found that the automated system recorded a similar emergency process at Substation 1 on VT 6 - 110 kV on bus 7 of the second bus system at the same time, also marked with a temporary marker.

In FIG. Fig. 6 “b” shows a graphical screen representation of the emergency process on the automated workplace of the operator of the upper hierarchical level 33, obtained by the operator when accessing the centralized file archive 37 from the second source of emergency oscillographic information PAC 13 (2) located at Substation 1.

As seen in FIG. 6 “b” on frame 1 during the time period marked by a temporary marker, in the power system the second source of emergency oscillographic information PAC 13 (2) at Substation 1 there was a surge in voltage in phase A and in phase B on VT 6 - 110 kV on the bus 7 second tire system.

In addition, at Substation 1 at PAC 13 (2) on VT 6 - 110 kV on bus 7 of the second bus system, a zero-sequence voltage surge was also detected at the same time, which allowed the power system operator to evaluate this information as a sign of an emergency process, recorded at Substation 1, which has become more global in nature for the power system and has already affected two sources of emergency oscillographic information at Substation 1.

In addition, at the same time, marked by a temporary marker, the power system operator, when viewing file information from a centralized file archive 37 from the first source of emergency oscillographic information PAC 13 (1) at Substation 2 (Fig. 6 "c"), found that the automated the system recorded at Substation 2 a similar emergency process on VT 6 - 110 kV on bus 7 of the first and second bus systems, as well as on VT 6 - 35 kV on bus 7 of the first bus system.

In FIG. 6 “c” is a graphical screen representation of the emergency process at the operator’s automated workstation of the upper hierarchical level 33, obtained by the operator when accessing the centralized file archive 37 from the first source of emergency oscillographic information PAC 13 (1) located in Substation 2.

As seen in FIG. 6 “c” on frame 1 during the time period marked by a temporary marker, in the power system, the third source of emergency oscillographic information PAC 13 (1) at Substation 2, a more significant surge in phase A and phase B voltage on VT 6 - 110 kV was recorded and VT 6 - 35 kV on bus 7 of the first and second bus systems.

In addition, at Substation 2 at PAC 13 (1) on VT 6 - 110 kV and VT 6 - 35 kV on bus 7 of the first and second bus systems, a voltage surge of zero sequences at the same time was also recorded (frame 1 of Fig. 6 “C”), which allowed the power system operator to evaluate this information as a sign of the development of an emergency process that has already covered two controlled objects in the power system, namely, Substation 1 and Substation 2, and which has already affected three sources of emergency oscillographic information PAC 13 (1) , RAS 13 (2) at Substation 1 and RAS 13 (1) at Sub Antium 2.

Thus, having received information about the detection of an emergency process in the power system recorded at Substation 1 and Substation 2, the operator of the power system, in order to obtain a general picture of the emergency process that has occurred in the power system, using information only from the centralized file archive 37, should immediately start sequential viewing of all other sources alarm oscillographic information located at all Substations (Substations 1, Substations 2 ... Substations n) included in the power system, from which emergency oscillographic information was received at the same time.

Performing such a viewing, the operator is forced to work with a huge amount of information, spending a fairly large amount of time, using information only from a centralized file archive 37, while the power system operator must be highly qualified and have extensive experience working with such information.

In global emergency processes that have covered many controlled electric power facilities that are part of the power system, even a very qualified and experienced power system operator cannot afford to give a general objective assessment of the entire emergency process recorded in the power system without using an automated information processing system.

The inventive automated system allows the operator of the power system to form an objective idea of the emergency process recorded in the power system as soon as possible in order to assess the mutual influence of the emergency processes recorded by various sources of emergency oscillographic information at various controlled electric power facilities included in the power system.

In order for the power system operator to get a generalized idea of the accident recorded in the power system using the inventive automated system, he must turn to the centralized channel-by-channel archive of emergency oscillographic information 39, selecting the accident sequence number N of interest to him, which is associated with the time interval of interest to the operator.

The inventive automated system, having performed automated processing of emergency oscillographic information, will present a generalized picture of the accident to the power system operator in the graphic screen forms shown in FIG. 7 a and FIG. 7 "b".

In FIG. 7 “a” is a graphical screen representation of the emergency process on the automated workstation of the operator of the upper hierarchical level 33, received by the operator when accessing the centralized channel-by-channel archive 39 from the first source of emergency oscillographic information PAC 13 (1) located in Substation 1 - frame 1, from the second source of emergency oscillographic information PAC 13 (2) located at Substation 1 - frame 2 and from the first source of emergency oscillographic information PAC 13 (2) located at Substation 2 - 3 etc. shown separate frames for each said source, but combined in a single video form. These frames 1, 2, 3 in FIG. 7 “a”, presented to the power system operator as a result of channel-by-channel processing of emergency oscillographic information by the automated system, are similar to the information provided to the power system operator by sequentially accessing the centralized file archive 37 for each of the three sources of emergency oscillographic information, which were given separately in the frame 1 in FIG. 6 “a” (corresponds to frame 1 in FIG. 7 “a”), in frame 1 in FIG. 6 “b” (corresponds to frame 2 in FIG. 7 “a”, to which currents in the OHL line 8–110 kV, phase currents) were added, in frame 1 in FIG. 6 "c" (corresponds to frame 3 in Fig. 7 "a").

Thus, as can be seen from FIG. 7 “a”, the claimed automated system allows the operator of the upper hierarchical level power system to simultaneously view on his AWP 33 in one video form information received from several sources of emergency oscillographic information located at different controlled electric power facilities included in the power system, and accordingly evaluate the mutual influence of emergency processes recorded at various Substations.

In order for the power system operator to compile a general idea of the accident, the claimed automated system allows the centralized channel-based processing of emergency oscillographic information to form a video form on the workstation 33 of the power system operator with a frame that contains information received in one time interval simultaneously from different sources of emergency oscillographic information located at various controlled electric power facilities included in the power system.

In FIG. 7 “b” is a graphical screen representation of the emergency process on the workstation of the operator of the energy system of the upper hierarchical level 33, obtained by the operator when accessing the centralized per-channel archive 39 with the formation of frame 4, giving a generalized idea to the operator about the accident recorded in the power system at Substation 1 and Substation 2 for all three sources of emergency oscillographic information PAC 13 (1), PAC 13 (2) Substation 1 and PAC 13 (1) Substation 2, as well as frames 1 and 2, giving an idea of the emergency process f, recorded separately by sources of emergency oscillographic information PAC 13 (1) Substation 1 - frame 1 and PAC 13 (2) Substation 1 - frame 2.

The inventive automated system allows the operator of the power system to view information on the accident recorded in the power system on his AWP 33 using his own video sequence templates for preparing information on the screen in the form of frames developed by the power system operator depending on his needs using various selection criteria for such information for display in the frame.

For example, if the operator of the power system of the upper hierarchical level is only interested in currents in the OHL lines 8 and only the voltages on the buses 7 at Substation 1, Substation 2 or Substation n, then the operator will see a video sequence with a storyboard based on these criteria on the ARM 33 screen, which will enable the operator power systems to get an initial general idea of the emergency process in the power system.

In addition, in the inventive automated system in the particular case of its implementation, the automated workstation (AWS) of the operator of the power system of the upper hierarchical level can be additionally equipped with a means of generating a file user archive of a generalized view of accidents recorded by the operator of the power system 44.

The algorithm of the means for generating a file user archive of a generalized view of accidents recorded by the operator of the power system 44, together with the algorithm of the workstation (AWP) of the operator of the power system of the upper hierarchical level 33, is shown in FIG. 8 a, FIG. 8 b and FIG. 8 "in".

As can be seen from the algorithm shown in FIG. 8 a, FIG. 8 b and FIG. 8 “c”, the operator of the upper hierarchical energy system in the course of its work to control the occurrence of emergency processes in the energy system has the opportunity to access on its AWP three archives of emergency oscillographic information: a centralized channel-by-channel archive of emergency oscillographic information (AOI) 39 and a centralized file archive of emergency oscillographic information (AOI) 37 generated on the server of the upper hierarchical level of the power system 24, as well as to the file user archive the generalized concept of accidents recorded by the operator of the power system generated by the means for generating, at the upper hierarchical level of the power system, a file user archive of generalized notions of accidents 44 generated by the operator of the power system operator of the upper hierarchical level 33.

If the operator of the power system of the upper hierarchical level wants to work with a centralized channel-by-channel archive of emergency oscillographic information (AOI) 39, then the block of algorithm 69 shown in Fig. 8 “a” transfers control to block 72 of the algorithm “Selection of a serial number from the centralized channel-by-channel archive of AOI 39 alarms accident N associated with the time interval of interest to the operator of the power system ”for selecting the number of the accident in the time interval of interest to the operator of the power system, while on the screen of ARM 33 the entire emergency process recorded in the power system is presented, presented in the form of a template disaggregated by frame of the alarm oscillographic information received from various sources of AOI located at various controlled substation level facilities included in the power system, giving a generalized idea of the accident in the power system (Fig. 7 "B").

Then the operator of the power system of the upper hierarchical level has the ability to view and analyze the information displayed on the screen of the AWP 33, and also has the ability to make written comments on the accident and document these comments. This function is performed by the algorithm block 75 “Viewing and analyzing accidents recorded in the power system at the workstation of the operator of the power system of the upper hierarchical level. Creation by the operator of the energy system of screen forms with the formation of AOI frames, giving the operator of the energy system a generalized idea of the accident. Documentation of written comments by the power system operator on the analyzed accident. ”

Upon completion of the process of viewing, analyzing and documenting comments on this emergency process, the energy system operator decides to save the results of his accident analysis in a file user archive of a generalized view of accidents recorded by the energy system operator 81. In this case, the algorithm transfers control to block 77, which copies from the central AOI archive of data on the emergency process selected by the operator of the power system of the upper hierarchical level In archive 81.

After completing this operation, the algorithm block 78 copies from the centralized channel-by-channel archive of the AOI the data on the main parameters (ΔT, Tkon, Tnach., Serial number N) of the accident selected by the operator of the power system of the upper hierarchical level to archive 81.

After that, the block of algorithm 79 copies from the centralized channel-by-channel archive of the AOI the data on the structure of the controlled electric power facilities included in the power system to archive 81.

The block of algorithm 80 completes the process of creating a file by storing it in a file user archive, which copies the upper hierarchical level of the contents of screen forms from the operator’s automated workstation with AOI, giving a generalized idea of the accident recorded in the power system, together with documented written comments of the power system operator on the accident , in the archive 81.

Thus, a file with a generalized idea of a specific accident in the power system is generated in the user file archive 81, information about which the operator of the power system of the upper hierarchical level wants to save for later viewing.

If the information about the accident received by the operator of the power system when viewing and analyzing in block 75 of the algorithm is not of further interest to him, then the block of algorithm 76 completes the work with the selected emergency process.

If the operator of the power system wants to access another archive, for example, a file user archive of a generalized view of accidents recorded by the operator of the power system 81, then control is transferred from block 69 of the algorithm to block 70 “Do you want to work with file "user archive of a generalized view of accidents recorded by the operator in the power system 81?".

The operation algorithm of the inventive automated system when the operator accesses the file user archive 81 is shown in FIG. 8 "b". At the same time, in block 70 of the algorithm, the question is solved whether the power system operator will work with the file user archive 81 previously created by him on his AWP 33. If yes, then block 73 of the algorithm selects information on a specific accident from the file user archive of a generalized view of accidents recorded by the operator in the power system 81.

Then the algorithm block 82 “View and analyze the selected accident recorded in the power system from the user file archive 81 on the workstation of the power system operator of the upper hierarchical level. Correction by the operator of the energy system of screen forms with the formation of new AOI frames, giving the operator of the energy system a generalized idea of the selected accident. Documenting the written new comments of the power system operator on the selected accident analyzed ”enables the power system operator to review and analyze the selected accident in the power system from the file user archive 81, for example, if, as a result of the subsequent work of the power system operator, circumstances arise that changed his understanding of his previously analyzed accident. As a result of repeated viewing by the operator of the power system of a selected accident from the file user archive 81, he may need to make new comments on this emergency process, to document these comments, for example, to provide other users in the power system.

If the power system operator decides to save the latest results of the analysis of the emergency process, then block 83 transfers control to algorithm block 84 “Copying from the file user archive 81 of accident data selected by block 73 of the algorithm to a new file of file user archive 81” and algorithm block 84 copies the accident data selected by block 73 of the algorithm to a new file of the file user archive 81.

Next, the block 85 of the algorithm "Copying from the file user archive 81 of accident data selected by block 73 of the algorithm to a new file of the file user archive 81 of data on the main parameters (ΔT, Tkon, Tnach., Serial number N) of the accident" copies to a new file file user archive 81 data on the main parameters (ΔT, Tkon ,. Init., sequence number N) of the accident selected by the block 73 of the algorithm.

Next, the algorithm block 86 “Copying from the file user archive 81 of accident data selected by the block 73 of the algorithm to the new file of the user file 81 about the structure of the controlled electric power facilities included in the power system” copies the information on the structure of the monitored files to the new file of the user file 81 electric power facilities included in the power system covered by the emergency process that was selected by block 73.

Next, block 87 of the algorithm “Copying from the operator’s power system operator the upper hierarchical level of the contents of new screen forms with AOI, giving a generalized idea of the selected accident recorded in the power system, together with documented new written comments by the operator of the power system to the selected accident, to a new file in the user archive file 81 »Copies the contents of the new AOI screen forms with a generalized edstavleniem about the accident, along with written comments documented new grid operator to select a block of 73 accidents.

If information about the accident received by the operator of the power system when viewing and analyzing in block 82 of the algorithm does not represent further interest for him, then block of algorithm 83 completes the work with the selected emergency process.

If the power system operator wants to turn to another archive, for example, to a centralized file archive of alarm oscillographic information 37, then control is transferred from block 70 of the algorithm to block 71 "Do you want to work with a centralized file archive of AOI?"

The operation algorithm of the inventive automated system when the operator accesses the centralized file archive AOI 37 is shown in FIG. 8 "in". At the same time, in block 71 of the algorithm, the question is solved whether the operator of the power system will work with the centralized file archive of AOI 37. If yes, then block 74 of the algorithm selects a file from the centralized file archive of AOI 37 in COMTRADE format from a specific source of alarm oscillographic information, recorded emergency process.

After that, block of algorithm 88 “Viewing and analysis of emergency oscillographic information in COMTRADE format from a specific source of emergency oscillographic information on the workstation of the operator of the power system of the upper hierarchical level. Creation by the operator of the energy system of screen forms with the formation of AOI frames from a specific source of emergency oscillographic information. Documentation of the written comments of the power system operator on the analyzed information ”provides the power system operator with the opportunity to sequentially view and analyze AOI in COMTRADE format from a specific source of emergency oscillographic information that recorded the emergency process.

Moreover, the power system operator has the ability to change the screen forms shown in FIG. 6 "a", FIG. 6 b and FIG. 6 “c”, change the AOI breakdown by personnel from a specific source of emergency oscillographic information, comment in writing and document comments on this emergency process.

If the power system operator decides to save the latest results of the analysis of the emergency process, then block 89 transfers control to block of algorithm 90 “Copying from the centralized file archive of emergency oscillographic information in COMTRADE format from a specific source of alarm oscillographic information in archive 81”, and block of algorithm 90 copies data from the alarm oscillographic information file selected by block 74 of the algorithm in COMTRADE format from a specific emergency oscillography source eskoy information from a centralized file archive 37 in the user archive file 81.

Next, block 91 of the algorithm "Copying from the centralized file archive of AOI data on the main parameters (ΔT, Tkon., Tnach., Serial number N) of the emergency process recorded from a specific source of emergency oscillographic information in the archive 81" copies the file to the user’s archive file 81 data on the main parameters (ΔT, Tkon., Tnach., Serial number N) of the emergency process recorded from a specific source of emergency oscillographic information.

Next, the block 92 of the algorithm “Copying from the operator’s power system operator the upper hierarchical level of the contents of screen forms with AOI from a specific source of emergency oscillographic information together with documented written comments by the operator of the power system to this information to archive 81” copies the file to the file of the user archive 81 from the operator’s workstation operator the contents of the AOI screen forms from a specific source of emergency oscillographic information created by the energy system operator s according to the selected algorithm block 74 along with an emergency process to that documented emergency process written comments grid operator.

If the information about the accident received by the operator of the power system when viewing and analyzing in block 88 of the algorithm is not of further interest to him, then block algorithm 89 completes the work with the selected emergency process.

If the operator of the power system is not interested in information from all the archives listed above, then the block of algorithm 71 terminates.

Thus, the inventive automated system allows the operator of the power system of the upper hierarchical level to receive generalized and reliable information about emergency processes recorded at all controlled electric power facilities included in the power system.

The inventive automated system allows you to create the basis for the subsequent automation of the assessment of the entire emergency process by the operator of the power system.
