In the technical scheme provided by some embodiments of the invention, the control system acquires the instruction of the operator control system in real time, after receiving the command of the switch to exit the backup power automatic switching logic, the voltage of the corresponding switch incoming line is set to be 0, and meanwhile, the uploading switch is manually allowed to the operator control system, so that the switch exiting the backup power automatic switching logic is completed; the control system collects instructions of an operator control system in real time, after receiving a command of recovering the backup power automatic switching logic of the switch, the incoming line voltage of the corresponding switch is set as a measured value, after the electrification confirmation, the switch automatically switches into the backup power automatic switching logic, and then the complete backup power automatic switching logic in an automatic mode is recovered, wherein the incoming line voltage of the corresponding backup power automatic switching switch is recovered to be normal/set to be 0 by receiving the command of switching into/out of the backup power automatic switching logic, the corresponding switch is manually allowed to be released, the corresponding backup power automatic switching switch is allowed to be manually switched, and the switch is withdrawn from the backup power automatic switching logic, so that the equipment maintenance is convenient in the backup power automatic switching automatic mode. The method realizes manual switch exit/input in the automatic backup power automatic switching mode, reduces power failure time, is flexible to operate, and improves maintenance efficiency.
These steps are described in detail below.
As shown in fig. 1 to 3, in step S110, the control system acquires an instruction of the operator control system in real time, sets the voltage of the corresponding switch incoming line to 0 after receiving a command of the switch to exit the backup power automatic switching logic, and uploads the manual branch permission of the switch to the operator control system, thereby completing the switch exit backup power automatic switching logic;
the control system collects the instruction of the operator control system in real time, monitors and manages the instruction of the operator control system, and ensures the transmission effectiveness of the instruction of the operator control system, and the instruction of the operator control system can be a command that the 10K20 switch exits the backup power automatic switching logic, but is not limited to this.
Correspondingly, the incoming line voltage of the corresponding switch is set to be 0, the incoming line voltage of the corresponding switch is changed under the operation of the instruction of the operator control system, and the obvious conversion is realized through digitization, so that the system can conveniently recognize the incoming line voltage.
When the incoming line voltage of the corresponding switch changes, the uploading switch is manually allowed to the operator control system, the manual operation stage of the operator control system is triggered, the switch quitting the spare power automatic switching logic is further completed, and the maintenance time is ensured to be sufficient.
In step S120, the control system collects an instruction of the operator control system in real time, after receiving a command of the switch to restore the backup power automatic switching logic, sets the incoming line voltage of the corresponding switch as a real measurement value, and after confirming the electrification, the switch automatically switches into the backup power automatic switching logic, thereby restoring the complete backup power automatic switching logic in the automatic mode.
The control system collects the instructions of the operator control system in real time, monitors and manages the instructions of the operator control system, and ensures the transmission effectiveness of the instructions of the operator control system.

In addition, the exit/input criterion adopts the incoming line voltage and the bus voltage as the criterion: when the switch is in an on position, the criterion is that the incoming line voltage is normal and the bus voltage is normal; when the switch is in a separated position, the criterion is that the incoming line voltage is normal.
The switch has closed position state, branch position state to realize the conversion under operation personnel's operation, thereby regulation and control inlet wire voltage, bus voltage, wherein, inlet wire voltage, bus voltage's contrast also can embody the state that the switch is in, consequently, through regulating and control different states in order to adapt to operation personnel's operation.
In addition, the whole operation process is monitored in real time, if the operation is not successful, a fault event is reported to remind an operator to carry out manual inspection and confirmation, and related control logics are realized by software programming without a specific spare power automatic switching hardware device.
When the switch is withdrawn/put in, manual confirmation is needed to prevent misoperation, so that the safety is further improved, the operation is completed only on the control system of the operator, other operations are not needed, simplicity and convenience are realized, and the time is saved.
Specifically, the switch configuration structure of the station power system according to the present embodiment is shown in fig. 2 and 3, and the station power system has two voltage levels: the 10kV section and the 400V section are respectively provided with a 10kV section bus and a 400 kV section, wherein the 10kV section bus consists of 1, 2 and 3 sections of buses, the 10kV 1 and 2 sections of buses are respectively supplied with power through a #1 station transformer and a #2 station transformer in the station, and the 10kV 3 section of buses are supplied with power through a standby station transformer; 10kV 1, 3 section generating lines are connected through bus tie switch 10K02, 10kV 2, 3 section generating lines are connected through bus tie switch 10K 03.

after the maintenance is finished, the operating personnel sends a command of the spare power automatic switching switch to put into the spare power automatic switching logic, and the incoming line voltage of the switch is recovered to be a measured value;
after the operator checks that no fault exists, the operator confirms that the switch is electrified, and the switch automatically switches into the spare power automatic switching logic, so that the complete spare power automatic switching logic under the automatic mode is recovered;
and monitoring the whole operation process in real time, and if the operation is unsuccessful, reporting a fault event to remind an operator to perform manual inspection and confirmation.
5. The method for controlling the automatic transfer switch according to claim 1, further comprising:
and monitoring the whole operation process in real time, and if the operation is unsuccessful, reporting a fault event to remind an operator to perform manual inspection and confirmation.
6. The method for controlling the automatic transfer switch according to claim 1, further comprising:
when the switch is withdrawn/put in, manual confirmation is needed to prevent misoperation.
7. A control device of a spare power automatic switching switch is characterized by comprising:
the first acquisition module is used for acquiring instructions of the operator control system in real time by the control system, setting the voltage of the corresponding switch incoming line to be 0 after receiving a switch standby power automatic switching logic exit command, and uploading a switch manual branch permission to the operator control system so as to finish the switch standby power automatic switching logic exit;
and the second acquisition module is used for acquiring the instruction of the operator control system in real time by the control system, setting the inlet line voltage of the corresponding switch as a real-time value after receiving a command of recovering the spare power automatic switching logic of the switch, and automatically switching into the spare power automatic switching logic after the electrification confirmation of the switch so as to recover the complete spare power automatic switching logic under the automatic mode.
8. A computer-readable program medium, characterized in that it stores computer program instructions which, when executed by a computer, cause the computer to perform the method according to any one of claims 1 to 6.
9. An electronic device, comprising:
a processor;
a memory having stored thereon computer readable instructions which, when executed by the processor, implement the method of any of claims 1 to 6.
