DETAILED DESCRIPTION

The embodiments are not limited to the embodiments described herein, and other embodiments of the invention will be apparent to a person skilled in the art based on the information set forth in the description and knowledge of the prior art without departing from the spirit and scope of the present invention.

The elements mentioned in the singular do not exclude the plurality of elements, unless specifically indicated otherwise.

The three-phase power supply in accordance with the present invention consists of three identical single-phase power supplies. Each such single-phase power supply can separately function in the power supply line of a single-phase consumer. Thus, the description below discloses both a single-phase intermediate power supply and a three-phase intermediate power supply consisting of three identical single-phase power supplies.

Said power source includes a capacitor module, a control unit, an induction module, input terminals configured to connect to the electrical network, and output terminals configured to connect to a consumer of electrical energy.

A single-phase power supply includes several inductors connected in parallel. In order to simplify FIG. 1 shows only one such inductor, and in an exemplary embodiment of the present invention, a single-phase power supply contains three such inductors connected in parallel, due to the need to create a stable power gradient along the power line when performing the main work. Three inductors according to an exemplary embodiment of the present invention provide the most stable circuit. The power gradient gives an increase of 20-25% at each stage (at each of the inductors). Each inductor provides its part of the balance and therefore the load is distributed evenly. In addition, if any of the inductors does not immediately reach the set power, the other two will adjust the balance. In this circuit, it is unlikely that all three inductors, or two at once, do not fall into the specified range of operation. This is only possible in the case of a physical violation of the integrity of the conductor from capacitors.

Mentioned inductors together form an induction power supply unit according to the present invention. Thus, in accordance with an exemplary embodiment of the present invention, the three-phase power supply contains nine inductors, three in parallel connected inductors in each phase, as shown in FIG. 2. Each such inductor (see Fig. 1) consists of a magnetic core, three measuring coils (T1, T2, T3) and three main coils (K1, K2, K3) wound on the core, and two coils (K1, K2) are in-phase, and the third coil (K3) is out of phase with the other two. Additionally, each inductor contains a ballast capacitor unit (BK). In an exemplary embodiment of the present invention, the ballast capacitor unit consists of twenty capacitors connected by a parallel array. A ballast capacitor block is connected between the coils K1 and K2 and is designed to suppress excess induction and ensure the balance of the device. When the charge accumulated in the ballast capacitor block overcomes the resistance R2 at the output to ground, its excess spreads to ground, thereby extinguishing excess induction.

A magnetic core is connected on one side to an input terminal (BK1), intended for connection to an electric network (C), and on the other hand, to an output terminal (VK2), intended to be connected to a consumer (P) of electric energy. Thus, through it directly passes the line of electricity consumption by the consumer. The magnetic core consists of several interleaved and stacked copper and ferromagnetic plates. In an exemplary embodiment, the magnetic core contains fourteen plates: seven copper and seven ferromagnetic. It is worth noting that alternative embodiments of the present invention are possible in which the magnetic core contains a larger number of plates, preferably the magnetic core contains an odd number of copper and an odd number of ferromagnetic plates. The said plates are coated using electroplating with a layer of aluminum and tin alloy with a ratio of 60/40 in order to ensure complete adherence of the plates to each other, eliminating the gap between the plates and increasing the metal bond. This allows you to reduce contact resistance between the plates and to avoid excessive heating of the core. When an electric current passes through a magnetic core while a consumer is supplying electrical energy, a closed uneven electromagnetic field is created in the inductor, the density of which is unstable, which generates an electromotive force (EMF) in the antiphase main coil. The unevenness of the electromagnetic field is a consequence of the different inductance of the core plates.

Measuring coils (T1-T3) are connected to the control unit and are configured to transmit measurements to the control unit. Mentioned measuring coils are designed to measure current in the consumer line. The measuring coils are located along the core of the inductor, with the first coil T1 located in the initial region of the core in the direction from the electrical network to the consumer, the second coil T2 located in the central part of the core, and the third coil T3 located in the final region of the core. This provides the ability to track the gradient of the current flowing in the inductor, and control the real power source based on the measurements.

The inductor contains three measuring coils, since this is the optimal amount for detecting current consumption peaks, and during operation, measurements are constantly compared between coils T1 and T2, as well as T3 and T2. And when there is a peak in consumption, the measurement readings between coils T1 and T2 and coils T3 and T2 can radically differ, up to 2-3 times. In normal mode, the measurement values of all three coils are almost the same.

Due to the connection scheme of the measuring coils T1-T3 with each other (see Fig. 1), a signal characterizing the arithmetic average of the measurements of three coils is supplied to the control unit from the measuring coils.

The capacitor module (KM) performs the work of accumulating and pumping the energy of the working circuit. A capacitor module includes a plurality of capacitors and is connected to the main coils of the induction module with the possibility of charging the capacitors by means of the induction current generated in the antiphase main coil K3 by means of an EMF and then discharging to the in-phase main coils K1 and K2. In an exemplary embodiment, the capacitor module of a three-phase power supply contains fifteen blocks of capacitors, each of which contains three capacitors (see Fig. 2). In a preferred embodiment, ultra-fast capacitors are used in the capacitor module.

In FIG. 3 (and further), the designations A1, B1, C1, A2, B2, C2, A3, B3, C3 indicate the lines connected to the corresponding inductors of each phase. Those. A1 is a line connected to the first inductor of phase A, etc. N denotes the neutral line. Thus, in a three-phase design, three phases immediately come out from each line of capacitor banks. Obviously, in the case of a single-phase execution of the power source, the capacitor block will have three lines of capacitors connected to the corresponding inductors.

Each capacitor block has a design feature: a built-in arrester in the form of a discharge / charge relay with a neutral circuit (see Fig. 4). The discharge / charge relay has three positions: “charge”, “discharge” and a zero position in which neither charging nor discharging occurs. For each inductor of each phase, a series of 5 parallel-connected capacitors is used. The line for charging and discharging capacitors is the same.

The control unit is connected to the measuring coils and is configured to receive measurement data from the measuring coils and control the charging / discharging of the capacitor module based on the measurements.

According to one embodiment of the invention, the control unit performs the gradient measurement of the capacitor discharge / charge line using induction current transformers (CTs) of the T-0.66 type in the amount of 90 pieces with 5A measuring probes at the output and up to 1000A measuring instruments on the measuring line (see Fig. 5). 30 CTs per one working phase or 10 per each capacitor discharge / charge line (see Fig. 6). Mentioned 10 CTs are evenly distributed along the capacitor charge / discharge line.

As shown in FIG. 6, 10 CTs are installed on the charging / discharging line of the capacitors of each inductor for performing a gradient measurement of the said line in order to find the arithmetic mean value, on the basis of which the balance of the inductors is built. The conclusions M1 and M10 of the above-mentioned TTs are connected to the conclusions of the measuring coils T1-T3 of the inductor. The remaining conclusions can be reserved in case the adjustment of the measurement process is carried out by connecting said conclusions to each other (described below). In addition, if there is a controller, the mentioned conclusions can be connected to the controller for taking measurements and controlling the operation of the device through the controller.

In this embodiment, the control unit is a “control matrix”, when connecting (inductive or direct) parts of which within each line, you can push the control algorithm to faster calculations, which leads to coarsening of the overall measurement gradient and reducing the time for making certain decisions for managing the main control algorithm. It also makes it possible, without connecting to external visual sources and other means of displaying control information (for example, an external console), to affect the device management process itself.

In this embodiment, a three-phase power supply, the control matrix is a block field (a set of lines of 10 current transformers each) of 90 measuring current transformers, which are grouped into three groups of thirty pieces, in turn, the groups are divided into subgroups of 10 pieces. After every 10 pieces of CT, a bus passes through which there is a pulse charging / discharging of the capacitor line in phases. Each group of thirty CTs is one phase, each phase is divided into three lines of capacitors. The control is carried out by measuring the current on this line with the internal CT winding, which transmits the information current to the external CT winding, where this information current is compared with the signal current from the measuring coils in the inductor and the circuit is balanced based on the comparison, while the internal CT winding is connected to main coils in the inductor. With a strong pulse during the discharge of the capacitors of the capacitor module, the current on the inner winding also becomes large, thus drowning out the excessive excitation of the antiphase main coil K3 in the inductor (using the balance through the external windings of the CT) to reduce the load and avoid overcharging, otherwise the current becomes smaller, and the excitation thereby becomes larger on the coil, in order to charge the capacitors.

Excessive induction current that has not gone into useful work is discharged to the ground loop. Thus, the balance of the system is achieved and its induction-pulse control is realized.

In an alternative embodiment, the control unit further includes a controller. The controller is connected to the measuring transformers of the control unit, and between the mentioned controller and the measuring CTs, an analog-to-digital converter (ADC) is installed, which supplies the hash stream of measurements to the controller. In an exemplary embodiment, the controller is connected to the first measuring transformer TT1. A hash stream (raster stream of values) is a stream of information from measuring coils from inductors and measuring CTs. When the measuring current passes from them through the ADC, it is converted to a hash stream that the controller already recognizes. In this case, the hash stream is a stream of values in the octal system from the measuring coils that passed through the ADC. That is, a stream of data having numerical values by which it is possible to calculate the arithmetic mean value over a period of time. Based on the incoming data, the controller controls the discharge / charging of the capacitor module.

The number and location of the CTs described above is due to the need for more accurate measurements along the current flow line along the capacitor line and is used to collect data for control based on the arithmetic mean numerical values coming from the measuring CTs to the ADC (in the case of a controller) in the form of non-attached and not converted to any or units of the hash stream, limited to 4 characters for simplicity and speed of calculation of the arithmetic mean value of the stream over time with an interval of 1800 seconds in increments of 0.5 seconds. This framework is enough to make management decisions at the level of the control algorithm. While charging the capacitors, the hash flow is negative.

The measurements are sent to the controller from the measuring CTs in the form of a variable voltage, then for a given period of time (about 30 minutes) statistics of peak loads on the consumption line are collected and the arithmetic average of the hash stream is calculated from the collected statistics, which is taken as a reference value for the next 30 minutes of measurements . In an exemplary embodiment, the reference value is recalculated every 30 minutes. Further, the control program, based on the incoming measurement readings and the reference value calculated in the previous step, controls the discharge / charge periods to ensure the balance of the system to maintain the capacitor-inductor circuit parameters, including capacitor capacitance and overcharge protection.

The control program in this exemplary embodiment is implemented as a program code stored on a storage medium and executed by a controller of a power supply control unit.

If the control is carried out by the balance through the control unit in the form of a control matrix, then when the voltage and current from the measuring coils in the inductor are exceeded, the capacitance of the resistors on the control matrix is exceeded, the balance current is reset, thus maintaining the balance corridor to maintain operating parameters.

The following is a description of an example of the operation of the intermediate power source disclosed above.

When an electric current passes through the magnetic circuits of the inductors, which have a galvanic connection with the power source and the consumer, a closed electromagnetic field is created in the magnetic circuits, which starts the excitation and creation of an inductive electromagnetic field on the main coils (K1-K3).

The measuring coils begin to read information and transmit it to the control unit, which begins to accumulate measurement statistics to calculate the arithmetic mean of the hash peak numbers coming from T1-TK and measuring transformers TT1-TT10. For 1800 seconds, the capacitors are in charging mode (their discharge / charge relays are in the "charging" position, as shown in Fig. 3) and are charged from the antiphase main coil (K3). After 1800 seconds, the first line of capacitors is discharged into the inductor coils (discharge / charge relays switch to the "discharge" position, as shown in Fig. 3), as a result of which ripples of the electromagnetic field generated by the current flow occur on the working coils K1 and K2, which provokes the appearance of a more powerful EMF in the electromagnetic core of inductors (reverse induction, a vortex field with reverse electromagnetic polarity), which provokes a shift of the output current from the input by 180 degrees and reduces the current at the input relative to the output by the pulse time.

The pulse itself, because of the speed of the process, does not spend all its potential on the additional EMF of the magnetic circuit, creates an excess of the induction current on the K3 coil (more precisely, a short-term redundancy of the reverse vortex field is created, which is in phase with the K3 coil), thereby creating a picture of a field similar to a vortex flow, and changing its magnetic properties, turning the charged stream into a current (due to self-induction, which is created under these conditions), sufficient and acceptable for charging capacitors (charging occurs from an excess field out of phase with the main field, i.e. vortex field, which is created at this moment and which is in the phase of the current flowing through the coil K3) located on the flow line of this process. After the capacitors of the capacitor block are discharged and the above-mentioned pulse is generated, which is detected by the T1-TK coils, the discharge / charge relay switches to the “charging” position. Energy is accumulated in capacitors from the antiphase coil K3, which “takes” current from the in-phase eddy field created by it. After the first pulse, the capacitors are not fully charged, and remain open for charging until the internal fuse closes the relay to the zero position in order to avoid overcharging (very briefly), after which a control signal is received, the relay closes to discharge and operation is repeated again. With the passage of time and a certain number of the above-mentioned operation of the circuit, a sufficient field redundancy is gradually created (accumulation of the vortex field potential) for continuous charging and discharging of the capacitor line. The capacitor unit is not fully charged from this redundancy, but from 30 to 90%, depending on the period and flux density at a given moment in time, the rest gets from the consumption line. This allows you to use part of the energy generated by the vortex field to charge the capacitors of the condenser unit and, therefore, reduces the energy consumption for the functioning of this power source.

In the case of turning off the consumer, the circuit "fades", until the next start of consumption.

For safety, excess inductive current from the K3 coil is discharged to the ground loop. In this case, we mean the unspent potential of the vortex field, before its transition to an increase in the resistance of the main conductor. To prevent this from happening instantly and to help in the appearance of this redundancy, a passive resistance is installed on the ground line from the K3 coil on all inductors (for a short delay in the discharge of the pulse excess of the vortex antiphase field). The process becomes autonomous and safe.

Thus, the core configuration forms an uneven electromagnetic field whose density is not constant, but when the capacitor line is discharged into this core, since the plates have different inductances, an electromagnetic field is created that becomes dense enough to charge the capacitors (the line that refers specifically to this inductor) . This process is repeated quite often (discretization about 5 times / sec), thus, based on this configuration, a closed balanced system is formed, which supplies additional power to the consumption line every 3rd period. This process is repeated on each phase 3 times in one period, since there are three lines of increase in current in each phase.

The task of the control algorithm is to maintain a balance between the discharge of capacitors in coils K1 and K2 and charging from coil K3. An important point should also be noted. Coil K3 charges capacitors both from the excess field density created by the discharge and from the inductance of the core itself when current is consumed by the consumer. It is understood that a balance has been reached between the periods of charging and discharging capacitors, which provides sufficient efficiency for the indicated effect.

You can influence the control of the device by switching the balance jumpers on the control matrix (see Fig. 5). If they are arranged in a certain order (the order is determined by measuring the current flow and consumer parameters), then you can set the time (period, without exact time) for starting and establishing the working balance, which is the main mode of the device, from about 30 minutes to about 48 hours. The need for such management depends on the consumer and his consumption model. If the consumer has a constant load that does not turn off, then you can enter the work quickly and not turn it off. If the consumer is a constantly changing load, then you need to choose a slow start, to check the operability of the power source for these types of loads. The primary jumper installation scheme (see Fig. 5) is universal for all types of consumers.

The power source described above can be used for reliable and uninterrupted power supply to consumers of electric energy.

Thus, based on the above description, it is possible to realize a single-phase / three-phase power supply in accordance with the present invention.

There are several scenarios for using this power supply.

Compensation of voltage drops in the network.

As a result of various causes, including various malfunctions, uneven load of the phases of the supply transformer, overload of the supply transformer at the substation, etc. temporary voltage drops in the electric network are possible. Such phenomena have a negative effect on consumers of electric energy, for example, critical to the level of supply voltage. The power supply in accordance with the present invention is configured to compensate for such voltage drops in the electrical network by means of the energy stored in the capacitor unit, to maintain the required level of supply voltage for the consumer for a given time. To this end, the power source through the measuring coils detects a voltage drop in the supply network, which can lead to abnormal operation of the consumer. By means of a control program programmed in the control unit, the power supply compensates for the voltage drop in the supply network by discharging the capacitors of the capacitor unit at predetermined times to supply additional energy to the consumption line.

Compensation for peaks in energy consumption by the consumer.

The functioning of the consumer of electrical energy may be associated with transients, which lead to fluctuations in the consumption of electrical energy by the consumer, accompanied by some peak values of consumption. This may be undesirable for various reasons. The power source in accordance with the present invention is configured to compensate for such peaks in energy consumption by the consumer. Moreover, at times of reduced consumer load, the power source can accumulate energy in the capacitor unit, and at times of peak consumption of electric energy by the consumer, the power source can compensate for this increased consumption, avoiding exceeding the specified values of instantaneous energy consumption from the network.

Decrease in consumption of electric energy from a network.

After the initial stage of charging the capacitors of the condenser unit, the power supply in accordance with the present invention can reduce the energy consumption from the electric network, while the consumer's consumption remains at the current level. The control unit in accordance with the control program controls the discharge of the capacitors so that the current generated in the consumption line due to the discharge of the capacitors reduces the current at the input of the power supply relative to the output for the duration of the pulse. In this case, a part of the energy of the discharge of the capacitors, unspent on the formation of additional current in the consumption line, is used to charge the said capacitors by means of antiphase winding, as described above. In view of this, a continuous decrease in the current at the input from the power source is created, while the current does not drop at the consumer. The process is discrete, but the sampling frequency is sufficient to maintain the picture in working condition for a given period of power consumption by the consumer.

Thus, the present invention allows for reliable and uninterrupted power supply to consumers of electric energy.

The application does not indicate specific software and hardware for implementing the control algorithm, but a specialist in the field of technology should understand that the invention is not limited to a specific software or hardware implementation, and therefore, any software and hardware known in the art can be used to implement the invention technicians. So hardware can be implemented in one or more specialized integrated circuits, digital signal processors, digital signal processing devices, programmable logic devices, user programmable gate arrays, processors, controllers, microcontrollers, microprocessors, electronic devices, and other electronic modules configured to carry out the functions described in this document, a computer or a combination of the above.

Although not specifically mentioned, it is obvious that when it comes to storing data, programs, and the like, a computer-readable storage medium is meant, examples of computer-readable storage media include read-only memory, random-access memory, register, cache semiconductor storage devices, magnetic media such as internal hard drives and removable drives, magneto-optical media and optical media such as CD-ROMs and digital versatile disks (DVDs), as well as any other storage media known in the art.

Although exemplary embodiments have been described in detail and shown in the accompanying drawings, it should be understood that such embodiments are merely illustrative and not intended to limit the broader invention, and that the invention should not be limited to the particular arrangements and structures shown and described, since various other modifications may be apparent to those skilled in the art.
