Detailed ways

The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the agent-based intelligent substation panorama information comprehensive integration display method of the present invention includes the following steps:

(1) The data in the monitoring host and the comprehensive application server are abstracted into various types of data. In this embodiment, the substation monitoring system collects data and comprehensively analyzes many results. According to its storage and transmission attributes, the data is abstractly divided into four types: resource data, real-time data, historical data, and alarm and report.

Resource data refers to graphic configuration screen files, report files, etc.; real-time data refers to the data collected by the system in real time and after standard processing; historical data refers to historical sampling data, statistical analysis data, protection recording files sent by protection devices, and equipment online The knife switch opening and closing stroke data files sent by the monitoring device; alarms and reports are generated by the monitoring system after intelligent processing. The alarm is generally a single article, and the report describes the more complex comprehensive analysis results.

The storage forms of the above four types of data are different, and the access interfaces are also different. Resource data is generally stored in files based on the file interface; real-time data uses the system’s real-time database access interface; historical data generally uses standard SQL access, or access through a simple packaged API; there is no standard access interface for alarms and reports, and is generally managed by the system. Define related APIs.

(2) The data access agents respectively set up on the monitoring host and the integrated application server access and manage various types of data through corresponding different access interfaces.

The data access agent of the present invention adopts the ORM (Object Relational Mapping, Object Relational Mapping) mechanism to organize various data, defines the models of four kinds of data in the XML file, and is responsible for the reading of the data organization model by the business object component, and The construction of business data objects; according to the different types of data, use their interfaces to access, and construct data in memory according to the model into business data objects with serializable and transportable uniform interfaces, as shown in Figure 1. The data model includes the abstract type of data, the specialty of the data, and the detailed content of the data.

This embodiment uses the system's real-time business data soft bus to complete the transmission of business data objects from the server (monitoring host and integrated application server) to the client (operator station). As shown in Figure 2, the Server module of the soft bus is deployed on the server, which is integrated in the data access proxy process; the Client module of the soft bus is deployed on the client. The data access agent constructs various types of data into business data objects with a unified interface, serializes the business data objects into data streams through the Server module of the soft bus, transmits them to the Client module of the client through the network through the soft bus, and then The business object component deserializes the data stream into business data objects, and the unified integrated display process of the client is based on the business data objects for comprehensive display and use.

(3) The data access agent transmits the data to the information client deployed on the operator station, and displays different types of data according to the corresponding display organization.

The data business scopes collected by the monitoring host deployed in the security zone I and the integrated application server deployed in the security zone II are different. The monitoring host mainly includes power grid operation data, grid fault data, relay protection information, and statistical analysis results, etc. The comprehensive application server mainly includes power transmission and transformation status monitoring data, secondary intelligent IED monitoring data in the station, auxiliary monitoring data (power supply, fire protection , security, etc.), and some other intelligent application calculation results. After the operator station receives the data transmitted by the data agent, it manages it according to the business and uses it for displaying various interfaces. The overall structural relationship is shown in Figure 3.

Panoramic display of the display effect provided by the client, customized professional display interface according to different professional needs, the display information basically corresponds to the four types of data in the monitoring host and comprehensive application server, including real-time images, real-time alarms, comprehensive analysis reports and history For information retrieval, after users of different majors log in to the system, the display interfaces provided by the system are also different.
