[0002] With the construction of the existing power system backup and dispatch system, the data interaction and emergency support capabilities between the main dispatch system and the backup dispatch system have been fully improved. The main and backup dispatch systems can meet the needs of rapid emergency response, build a dual-active main and backup dispatch system, realize the rapid and flexible deployment of dispatch emergency technical means, and gradually form a dispatch emergency system that meets all-round emergency needs. This is an inevitable requirement for the current development of the main grid.

[0003] As a basic and important function of modern power grid dispatching control, automatic voltage control (AVC) is the most advanced form of voltage / reactive power control currently pursued. It combines safety and economy, can achieve economic closed-loop control under safety constraints, and is recognized as the highest stage of power system dispatching control development.

[0004] The automatic voltage control active-active system is an important component of building active-active primary-standby dispatching.

[0005] Obviously, to establish a dispatching emergency system that can meet all-round emergency needs, it is necessary to realize dual-activity of automatic voltage control for the main and standby dispatching of the power grid. Summary of the invention

[0006] The purpose of the present invention is to solve the above problems and provide a method and device for automatic voltage control dual activity of the main and standby dispatching systems of the power grid. Through the automatic voltage control dual activity of the main and standby dispatching systems, the main dispatching AVC and the main dispatching AVC of the main grid are realized, and real-time information interaction is achieved, thereby realizing the coordinated control of the voltage and reactive power of the main and standby dispatching.

[0007] The technical solution adopted by the present invention to solve the technical problem is:

[0008] In a first aspect, a dual-active method for automatic voltage control of a main and standby dispatching system of a power grid is applied to a voltage and reactive power coordinated control system; the system includes a main dispatching AVC of a main grid and a main standby dispatching AVC of a main grid; the method steps include:

[0009] Model maintenance: The main and standby AVC systems also have the AVC model maintenance function. When one system performs AVC model maintenance, the model maintenance information is automatically synchronized to the other system. When the other system detects changes in model information in real time, it automatically performs corresponding model maintenance.

[0010] Model synchronization verification: The coordination control layer performs the AVC model synchronization verification function of the main and standby dispatching systems in real time, obtains the main and standby dispatching models for comparison, and displays inconsistent model information. When there is a parameter inconsistency that affects the safe operation of AVC, the AVC function of the main and standby dispatching systems is stopped.

[0011] Model synchronization: Automatically synchronize the AVC models of the main and standby dispatching systems by type or by plant through manual confirmation.

[0012] AVC optimization calculation: The main and standby control systems AVC perform AVC optimization calculations simultaneously based on the model information and real-time data within their respective systems to generate control instructions.

[0013] AVC control execution: When a control instruction is issued, it automatically checks whether the device corresponding to the control instruction has control authority, and issues instructions with control authority for execution to complete AVC closed-loop control.

[0014] Optionally, model maintenance includes, in addition to regular model parameters:

[0023] The AVC algorithm optimization operation is active-active, and the main and standby AVCs perform AVC algorithm optimization operations according to the AVC models of their respective systems and real-time grid data, and each generates a control instruction. After the main and standby systems are switched, the AVC operation does not need to be manually switched.

[0024] The control is active-active. After the main and backup AVCs each generate control instructions based on the AVC algorithm optimization, they obtain the control authority of the control object corresponding to the instruction, whether it is the main control or the backup control, and then according to the current system status, whether it is the main control or the backup control. When the control authority of the device matches the system status, control can be issued. AVC control is active-active. The same control device can only be controlled on one side of the system, ensuring the security of control.

[0026] The model maintenance active-active module is used for real-time synchronization maintenance of the active and standby AVC models to ensure the consistency of the active and standby models.

[0027] The model synchronization verification module is used to determine whether the main and standby AVC models are consistent and to detect whether there are parameters that affect the safe operation of AVC. If so, the main and standby AVC functions are exited.

[0030] The AVC control execution module is used to determine whether the active and standby states of the current system are consistent with the control authority of the control device corresponding to the control instruction after the active AVC and the standby AVC generate the control instruction. If they are consistent, the module issues the control instruction for execution.

[0031] Optionally, the device further comprises:

[0032] Active-active information specification module, used to standardize the interactive information between the main AVC and the backup AVC. Active-active information includes

[0036] AVC power plant planning curve information: today's voltage curve and tomorrow's voltage curve.

[0037] The AVC control execution module includes:

[0038] The controllable determination submodule is used to obtain the control device to which the control instruction belongs after the main and standby AVC control strategy is generated, and to check whether the device is controllable;

[0039] The first judgment submodule is used to obtain the main and backup control states of the system and the control authority state (main control or backup control) of the object to which the control instruction belongs when a control instruction exists, and to determine whether the two states are consistent; if not, no control is issued; if so, control is issued for execution.

[0041] In a fourth aspect, the present invention provides a readable storage medium, on which a program or instruction is stored, and when the program or instruction is executed by a processor, the steps of the method described in the first aspect are implemented.

[0042] It can be seen from the above technical solutions that the present invention has the following advantages:

[0043] The present invention has the AVC model maintenance function through the main and standby adjustment system AVC. When one side system performs AVC model maintenance, the model maintenance information is automatically synchronized to the other side system. When the other side system detects the model information change in real time, it automatically performs the corresponding model maintenance. The coordination control layer performs the AVC model synchronization verification function of the main and standby adjustment system in real time, obtains the main and standby adjustment models for comparison, and displays inconsistent model information. When there is a parameter inconsistency that affects the safety of AVC operation, the AVC function of the main and standby adjustment system is stopped. Through manual confirmation, the AVC model of the main and standby adjustment system is automatically synchronized according to type or plant station.

When the other side system detects the model information change in real time, it automatically performs the corresponding model maintenance. The coordination control layer performs the AVC model synchronization verification function of the main and standby dispatching system in real time, obtains the main and standby dispatching models for comparison, and displays inconsistent model information.

The coordination layer provides tools to periodically compare the strategies and models of the main and backup dispatching systems. The method steps include:

[0059] Step S201, the main and standby dispatching systems AVC also have the AVC model maintenance function.
