The apparatus can be configured in a terminal device or a server, and the method specifically includes:
and S110, acquiring the operation control strategy of the current transformer substation, and auditing the operation control strategy.
The transformer substation is a place for converting voltage and current, receiving electric energy and distributing electric energy in an electric power system, and mainly has the functions of converting voltage, distributing electric energy, controlling the flow direction of electric energy, adjusting voltage and the like.
The control strategy refers to a strategy and a method for controlling a certain system or instrument. In a transformer substation, a control strategy refers to a strategy of selecting a main transformer tap in the transformer substation for gear shifting or switching a capacitive reactor and the like. The main transformer tap is a tap on a primary side coil or a secondary side coil of the transformer and is used for adjusting secondary side voltage. According to the magnetic field theory, the voltage ratio of two sides of the transformer is in direct proportion to the turn ratio of the two coils, so that the secondary side voltage can be adjusted by adjusting the number of turns of the coils, and the tap is used for adjusting the number of turns of the coils. The control strategy comprises an open-loop control strategy, a semi-closed-loop control strategy and a closed-loop control strategy. The open-loop control strategy refers to outputting a strategy suggestion for controlling the equipment to be controlled. The operation control strategy refers to a control strategy for automatically controlling the transformer substation by the system. And auditing the operation control strategy refers to detecting whether the operation control strategy is accurate or not. The operation control strategy can be audited by adopting an auditing mode corresponding to the type aiming at the type of the operation control strategy.

The semi-closed loop control strategy refers to that an operation control strategy is given and confirmed by monitoring personnel or a remote control remote regulation instruction is sent by an operation system of the current transformer substation after the confirmation of the monitoring personnel and dispatching personnel. The closed-loop control strategy is to give an operation control strategy and send a remote control and remote regulation instruction through an operation system of the current transformer substation. The remote control and remote regulation instruction refers to remote control of some switch control devices and remote regulation of remote control quantity, wherein the switch control devices comprise at least one of the following items: the system comprises a circuit breaker, a reactive power compensation device, a power regulation device, an on-load voltage regulation transformer tap, a hydraulic generator, a thermal power generating unit and the like. In an embodiment of the invention, the switching control device comprises a transformer tap or a capacitive reactor or the like.
In addition, the obtaining of the operation control strategy of the current substation comprises: setting parameters in a strategy calculation server, wherein the parameters at least comprise an automatic voltage control period, a current system control mode, a strategy state check period and a strategy timeout interval; when an automatic voltage control period comes, at least reading a power grid model and real-time measurement data from a monitoring system, constructing a complete topological structure and forming a control unit, wherein the topological structure comprises various devices in a transformer substation and the connection relation among the devices; and generating operation control strategies of all the control units according to the real-time data of the devices in the control units. A monitoring system of the transformer substation, also called as an SCADA (Supervisory Control And Data Acquisition) system, is responsible for acquiring all measurement Data information in the transformer substation. The measurement information is collected to a monitoring system, is correspondingly associated to corresponding equipment, and is displayed on a display screen for a dispatcher to monitor the operation condition of the transformer substation. Meanwhile, the measurement data can be packaged and provided for other module applications to use, for example, the AVC needs basic data collected from the substation when performing calculation, and the source of the basic data collected from the substation is not directly collected from actual equipment of the substation, but is measurement data of the substation obtained from the SCADA system.
In addition, the auditing terminal is used for manually auditing the operation control strategy. The timeout auditing is used for judging whether the processing time for operating the control strategy is too long, specifically, judging whether the time difference between the current time and the strategy generation time is less than the strategy timeout interval, if so, indicating that the time is not exceeded, otherwise, judging that the time is exceeded. If not, the operation control strategy is continuously processed, if yes, the operation control strategy is not continuously processed, and the operation control strategy is discarded and prompted to the user. In the embodiment of the present invention, the state of the operation control policy is configured to indicate whether the audit is passed, for example, whether the audit terminal passes the audit or whether the audit is passed after time out. And meanwhile, updating the current state of the operation control strategy according to the auditing condition.

Inquiring the device remote control information of the device corresponding to the operation control strategy in the operation system of the current transformer substation refers to reading the device remote control information from the operation system of the current transformer substation. And the equipment remote control information audit is used for detecting whether the equipment remote control information is complete or not so as to generate a remote control instruction.
It should be noted that the determination that the device remote control information is approved means that the device remote control information is approved when the corresponding device remote control information is read from the power grid monitoring, and otherwise, the device remote control information is not approved. The state of the operation control strategy configured in the embodiment of the invention can also be used for indicating whether the equipment remote control information is approved or not, and updating the current state of the operation control strategy according to whether the equipment remote control information is approved or not. The equipment remote control information is approved to show that the equipment remote control information can be extracted from the current transformer substation operation system so as to generate a remote control instruction; the device remote control information is not checked, which indicates that the device remote control information extracted from the current transformer substation operation system is empty or incomplete, a remote control command cannot be generated, the current transformer substation operation system cannot be controlled, and voltage control cannot be realized.
By auditing the remote control and remote measurement information of the equipment, the remote control and remote measurement instruction can be accurately generated and the normal operation of the current transformer substation operation system is ensured.
And S130, when the equipment remote regulation remote control information is approved, generating a remote regulation remote control instruction, and sending the remote regulation remote control instruction to the current operation system of the transformer substation so as to respond to the remote regulation remote control instruction.
The remote control command is used for controlling switch control equipment in an operation system of the current transformer substation, and specifically, controlling a transformer tap or a capacitive reactor and the like in the operation system of the current transformer substation. Responding to the remote control remote regulation instruction means that the remote control remote regulation instruction is sent to a rear operation system in an operation system of the current transformer substation and the rear operation system executes the remote control remote regulation instruction. And whether the operation system of the current transformer substation successfully receives the remote control command or not and whether the remote control command is successfully responded can also be detected. The state of the operation control strategy configured in the embodiment of the invention can also be used for indicating whether the remote regulation remote control command is successfully received and whether the remote regulation remote control command is successfully responded, and updating the current state of the operation control strategy according to whether the operation system of the current transformer substation successfully receives the remote regulation remote control command and whether the remote regulation remote control command is successfully responded.
