[0045] The embodiment of the present application provides a method for automatically matching a segmenting press plate of a main transformer backup protection. Figure 1 A flowchart of a method for automatically matching a segmenting press plate of a main transformer backup protection is provided in the embodiment of the present application. The embodiment can be applied to a scenario in which the medium voltage side bus of the main transformer is in a double bus double segment connection mode. The method can be executed by a main transformer backup protection automatic matching segmenting press plate device, which can be realized in the form of hardware and / or software. As shown in Figure 1 The method comprises the following steps.

[0046] S110, acquiring position information of the main transformer medium voltage side switch, the bus coupler switch and the segment switch.

[0047] Specifically, Figure 2 is a wiring mode schematic diagram of a main transformer backup protection automatic matching segmenting press plate provided by the embodiment of the present application. As Figure 2As shown, the main transformer medium voltage side switch 10 is a circuit breaker on the medium voltage side of the main transformer 40, one end of the main transformer medium voltage side switch 10 is connected to the main transformer 40, and the other end is connected to the bus. The bus tie switch is a circuit breaker for connecting two buses, one end of the bus tie switch is connected to one bus, and the other end of the bus tie switch is connected to the other bus. The section switch is arranged on each bus to divide one bus into two sections. The double-bus double-section connection mode of the power grid is for a power grid system with two buses, each bus is divided into two sections by arranging a section switch on each bus, and the bus tie switch is used to connect the two sections on the same side of the section switch on the two buses to realize the double-bus double-section connection mode. The section switch 30 divides one bus into two sections, one of which is the first bus 51 and the other of which is the fifth bus 53; the section switch 31 divides the other bus into two sections, one of which is the second bus 52 and the other of which is the sixth bus 54. Among them, the first bus 51 and the second bus 52 are configured by one set of main transformers, and the fifth bus 53 and the sixth bus 54 are configured by another set of main transformers. The other end of the main transformer medium voltage side switch 10 has two bus disconnectors, one of which is connected to the first bus 51 and the other of which is connected to the second bus 52. The position information of each switch is the state of the switch, which can include the closed state and / or the open state of the switch. The position information of the main transformer medium voltage side switch, the bus tie switch and the section switch can be obtained by the background dispatching.

[0048] S120, determine whether the main transformer medium voltage side switch is in the closed state; if yes, go to S130; if no, exit the automatic matching of the section jumper.

[0049] Specifically, according to the obtained position information of the main transformer medium voltage side switch, the bus tie switch and the section switch, the position of each switch is determined to be in the closed state or the open state according to the preset switch state determination logic. If it is determined that the position of the main transformer medium voltage side switch, the bus tie switch and / or the section switch is in the open state, it is possible that the main transformer is not connected to the bus for work. Therefore, it is not necessary to configure the section jumper of the section switch to be put into operation or cut off.

[0050] S130, determine whether the section switch is in the closed state; if yes, go to S140; if no, exit the automatic matching of the section jumper.

[0051] Specifically, after it is determined that the bus tie switch and the section switch are both in the closed state, the state of the main transformer medium voltage side switch is determined according to the state of the bus disconnector at the other end of the main transformer medium voltage side switch, and it is determined that the main transformer medium voltage side switch is in communication with the first bus or the second bus.

[0052] S150, judge whether the bus knife switch of the main transformer medium voltage side switch is located in the first bus; if yes, turn to S160; if not, turn to S170.

[0053] S160, the bus knife switch of the main transformer medium voltage side switch is located in the first bus, then put in the jump section pressure plate connected with the first bus or confirm that the jump section pressure plate is in the put-in state.

[0054] Specifically, the main transformer medium voltage side switch is in communication with the first bus, then the first bus is connected to the main transformer medium voltage side switch for work. Therefore, the jump section pressure plate of the section switch connected with the first bus is put in, or it is confirmed that the jump section pressure plate of the section switch connected with the first bus is in the put-in state. Based on the above operation, in the process of the background dispatching for the main transformer bus inversion operation, if the main transformer medium voltage side switch fails to be correctly and timely cut off, the section switch connected with the second bus can be automatically cut off, thereby playing a role of the main transformer backup protection, effectively preventing the expansion of the fault range.

[0055] S170, the bus knife switch of the main transformer medium voltage side switch is located in the second bus, then put in the jump section pressure plate connected with the second bus or confirm that the jump section pressure plate is in the put-in state.

[0056] Specifically, the main transformer medium voltage side switch is in communication with the second bus, then the second bus is connected to the main transformer medium voltage side switch for work. Therefore, the jump section pressure plate of the section switch connected with the second bus is put in, or it is confirmed that the jump section pressure plate of the section switch connected with the second bus is in the put-in state. Based on the above operation, in the process of the background dispatching for the main transformer bus inversion operation, if the main transformer medium voltage side switch fails to be correctly and timely cut off, the section switch connected with the second bus can be automatically cut off, thereby playing a role of the main transformer backup protection, effectively preventing the expansion of the fault range.

[0057] The technical scheme of the embodiment, by acquiring the position information of the main transformer medium voltage side switch, the bus coupler switch and the section switch, when the main transformer medium voltage side switch, the bus coupler switch and the section switch are all in the closed state, the position of the bus knife switch of the main transformer medium voltage side switch is judged. If the bus knife switch is located in the first bus, the jump section pressure plate connected with the first bus is put in or determined to be in the put-in state; if the bus knife switch is located in the second bus, the jump section pressure plate connected with the second bus is put in or determined to be in the put-in state. This method of automatically configuring the jump section pressure plate can automatically configure the jump section pressure plate of the section switch after the background dispatching completes the main transformer bus inversion operation, without the need for staff to configure the main transformer backup protection jump section pressure plate according to the wiring mode in the transformer field, thereby improving the configuration efficiency and ensuring the accuracy of the device operation. Moreover, it can effectively avoid the situation that the power grid is in the mismatch of the main transformer backup protection during the period from the completion of the main transformer bus inversion operation to the on-site configuration of the jump section pressure plate, thereby preventing the expansion of the power grid accident range.

[0058] Optionally, the embodiment is a refinement of the above-mentioned embodiment of acquiring the position information of the main transformer medium voltage side switch, the bus tie switch and the sectionalizing switch. The position information of the main transformer medium voltage side switch, the bus tie switch and the sectionalizing switch is transmitted to the background dispatching from the state information of the switch and the knife switch.

[0059] Specifically, the main transformer medium voltage side switch, the bus tie switch and the sectionalizing switch are each provided with a knife switch, and the knife switch is provided on the current inflow side and the current outflow side of the switch, and the number of the knife switch on each side is at least one, which is not limited herein. Exemplarily, the number of the bus bar knife switch on the side connected with the main transformer medium voltage side switch and the bus bar is two. The position information of the main transformer medium voltage side switch, the bus tie switch and the sectionalizing switch can be generated from the position state information of the knife switch, and the state information is transmitted to the controller of the background dispatching, so that the background dispatching receives the signal to acquire the position information of the main transformer medium voltage side switch, the bus tie switch and the sectionalizing switch. Optionally, the state information of the switch and the knife switch includes the state information of the switch and the state information of the auxiliary contact connected with the knife switch. Specifically, the knife switch of the main transformer medium voltage side switch, the bus tie switch and the sectionalizing switch is connected with an auxiliary contact. The auxiliary contact can be connected with an indicator light circuit, which is used to determine that each switch is in the closed position or the open position according to the position of the knife switch of each switch, and can be displayed through the indicator light. The auxiliary contact can also be connected with a signal transmission circuit, which is used to transmit the state information of the connected switch to the remote background dispatching controller, so as to realize the real-time monitoring of the state of the main transformer medium voltage side switch, the bus tie switch and the sectionalizing switch by the background dispatching, and perform the main transformer bus tie operation according to the switch state, and configure the main transformer backup protection sectionalizing pressure plate to automatically perform the corresponding action.

[0060] Optionally, Figure 3 is a flowchart of another method for automatically matching and jumping sectionalizing pressure plate of main transformer backup protection provided by the embodiment of the application. The embodiment is a refinement of the acquisition of the position information of each switch in the above-mentioned embodiments. As shown in the figure, Figure 3 the method for automatically matching and jumping sectionalizing pressure plate of main transformer backup protection includes the following steps:

[0061] S210, acquiring the switch remote signaling of the main transformer medium voltage side switch, the bus tie switch and / or the sectionalizing switch.

[0062] Specifically, the switch remote signaling is the state quantity of the switch, and the position signals such as the switch, the knife switch and / or the central signal are uploaded to the background dispatching controller, so that the background dispatching monitors the switch state and performs the corresponding operation according to the switch state. The switch remote signaling of the main transformer medium voltage side switch, the bus tie switch and / or the sectionalizing switch is transmitted to the background dispatching through the remote signaling contact connected with the switch, so that the background dispatching acquires the state information of the main transformer medium voltage side switch, the bus tie switch and / or the sectionalizing switch.

[0063] S220, acquire position information of the two sides of the circuit connected with the main transformer medium voltage side switch, the bus tie switch and / or the sectionalizing switch.

[0064] Specifically, the main transformer medium voltage side switch, the bus tie switch and / or the sectionalizing switch have at least one switch on the current inflow side and the current outflow side, and the position information of the switch can include the position of the switch in the closed position and the position of the switch in the open position. The position information of the switch of the main transformer medium voltage side switch, the bus tie switch and / or the sectionalizing switch can be transmitted to the background dispatching through the auxiliary contact connected with the switch, so that the background dispatching acquires the position information of the switch of the main transformer medium voltage side switch, the bus tie switch and / or the sectionalizing switch.

[0065] S230, judge whether the main transformer medium voltage side switch is in the closed position; if yes, turn to S240; if no, exit the automatic matching of the sectionalizing pressure plate.

[0066] S240, judge whether the sectionalizing switch is in the closed position; if yes, turn to S250; if no, exit the automatic matching of the sectionalizing pressure plate.

[0067] S250, judge whether the bus tie switch is in the closed position; if yes, turn to S260; if no, exit the automatic matching of the sectionalizing pressure plate.

[0068] S260, judge whether the bus switch of the main transformer medium voltage side switch is in the first bus; if yes, turn to S270; if no, turn to S280.

[0069] S270, the bus switch of the main transformer medium voltage side switch is in the first bus, then put in the sectionalizing pressure plate connected with the first bus or confirm that the sectionalizing pressure plate is in the put-in state.

[0070] S280, the bus switch of the main transformer medium voltage side switch is in the second bus, then put in the sectionalizing pressure plate connected with the second bus or confirm that the sectionalizing pressure plate is in the put-in state.

[0071] Optionally, Figure 4 is a switch state judgment logic diagram of a method for automatically matching the sectionalizing pressure plate of the main transformer backup protection provided by the embodiment. The embodiment is a refinement of the method for determining whether the position of each switch is in the closed position in each of the above embodiments. As shown in the figure, the method for judging whether the main transformer medium voltage side switch, the bus tie switch and the sectionalizing switch are in the closed position is as follows: Figure 4

[0072] If the switch remote signaling quantity of the main transformer medium voltage side switch, the bus tie switch and / or the sectionalizing switch is in the closed position, and there is only one switch in the closed position on each side connected with the circuit, then the position information of the main transformer medium voltage side switch, the bus tie switch and / or the sectionalizing switch is in the closed position. ​

[0073] Specifically, the position information of the main transformer medium voltage side switch, the bus tie switch and / or the section switch can be determined by the following judgment logic: when the remote signaling contact of the main transformer medium voltage side switch, the bus tie switch and / or the section switch transmits a signal to the background dispatching, the signal shows that the switch remote signaling of the main transformer medium voltage side switch, the bus tie switch and / or the section switch is in the closed position, and the auxiliary contact of the switch breaker transmits a signal to the background dispatching, the signal shows that the current inflow side and the current outflow side of the main transformer medium voltage side switch, the bus tie switch and / or the section switch are both and only one breaker is in the closed position. When the two conditions are met at the same time, it can be determined that the position information of the main transformer medium voltage side switch, the bus tie switch and / or the section switch is in the closed position.

[0074] Optionally, Figure 5 is another switch state judgment logic diagram of the method for automatically matching the backup protection of the main transformer to jump the section pressure plate provided by the embodiment of the application. The embodiment is a refinement of the determination of whether the position of each switch is in the closed position in the above-mentioned embodiments. As shown in Figure 5 , the method for determining whether the main transformer medium voltage side switch, the bus tie switch and / or the section switch is in the open position is as follows:

[0075] If the switch remote signaling of the main transformer medium voltage side switch, the bus tie switch and / or the section switch is in the open position, the position information of the main transformer medium voltage side switch, the bus tie switch and / or the section switch is in the open position.

[0076] Specifically, the position information of the main transformer medium voltage side switch, the bus tie switch and / or the section switch can be determined by the following judgment logic: when the remote signaling contact of the main transformer medium voltage side switch, the bus tie switch and / or the section switch transmits a signal to the background dispatching, the signal shows that the switch remote signaling of the main transformer medium voltage side switch, the bus tie switch and / or the section switch is in the open position, and the auxiliary contact of the switch breaker transmits a signal to the background dispatching, the signal shows that the current inflow side and the current outflow side of the main transformer medium voltage side switch, the bus tie switch and / or the section switch are both and only one breaker is in the closed position. When the two conditions are met at the same time, it can be determined that the position information of the main transformer medium voltage side switch, the bus tie switch and / or the section switch is in the closed position.

[0077] Optionally, continuing to refer to Figure 5 , the embodiment is a refinement of the determination of whether the position of each switch is in the closed position in the above-mentioned embodiments. The method for determining whether the main transformer medium voltage side switch, the bus tie switch and / or the section switch is in the open position can also be as follows: if all the breakers on any side connected with the main transformer medium voltage side switch, the bus tie switch and / or the section switch are in the open position, the position information of the main transformer medium voltage side switch, the bus tie switch and / or the section switch is in the open position.

[0078] Specifically, the position information of the main transformer medium voltage side switch, the bus tie switch and / or the section switch can also be determined by the following judgment logic: when the signals transmitted by the auxiliary contacts connected by the breakers of the switches to the background dispatching show that the current inflow side and the current outflow side of the main transformer medium voltage side switch, the bus tie switch and / or the section switch, all the breakers of any side are in the open position, the condition is also met to determine that the position information of the main transformer medium voltage side switch, the bus tie switch and / or the section switch is the split position. Exemplarily, when one of the breakers included in the current inflow side of the main transformer medium voltage side switch is in the open position, or both of the breakers included in the current outflow side of the main transformer medium voltage side switch are in the open position, it can be determined that the position information of the main transformer medium voltage side switch is the split position.
