fig. 2 and fig. 3 are schematic diagrams of an example of a master/slave control right switching tool of a grid-level power dispatching system according to the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example 1
This embodiment introduces a method for switching master/slave control rights of a grid-level power scheduling system, including:
the master control system enters the control right and exits the process, which comprises the following steps:
checking the running state of the core application of the main dispatching system;
when the application is normal, the high-level application function which issues the control command exits;
quitting the automation control right and the scheduling control right;
forbidding the system control right after the master control system control queue is executed;
controlling the front channel to be blocked;
after the master dispatching system control right quits, the standby dispatching system starts to put into control right, comprising:
checking the control right of the master dispatching system and the core application state of the standby dispatching system;
when the control right of the main dispatching system is quitted and the core application state of the standby dispatching system is normal, the front channel of the standby dispatching system recovers control;
putting into automation and scheduling control right and system master control right;
and issuing a control command, and putting high-level application functions into use.
As shown in fig. 1, an application process of the method for switching master/standby control rights of a grid-level power scheduling system provided in this embodiment specifically involves the following steps:
1) checking the core application state of the master system. And normally carrying out the next step, otherwise, checking abnormal application, and entering the next step after the normal application is recovered.
2) The high-level application function issuing the control command exits. These application functions mainly include: automatic power generation control, automatic voltage control, automatic direct current control, automatic energy storage control, automatic start-stop control of an energy storage power plant, planned issuing and the like. Each functional module is exited one by one until all are successfully exited.
3) Quitting the automation control right and quitting the scheduling control right. The automatic control right quits, the automatic personnel logs in, and quits after the authority is verified; the dispatching control right is logged in by a dispatcher, and the dispatcher logs out after checking the authority.
4) And forbidding the system control right after the system control queue is executed. After the scheduling and automation control right exits, the system control right exits after the inventory control is required to be executed after the control commands which are executed possibly exist in the system.
5) And pre-channel blocking control. The front module is responsible for the downward interaction and can be blocked only after the execution of the existing control queue is finished. In addition, the control command is issued to the transformer substation through the preposition, and the last gate issued by control is closed through blocking the preposition channel.

1) and checking the control right of the master dispatching system and the core application state of the standby dispatching system. Firstly, the control right of the master dispatching system is confirmed to be quitted, and the core application state of the standby dispatching system is ensured to be normal.
2) And recovering the control of the preposed channel of the standby dispatching system.
3) Putting into automation and scheduling control right and system master control right;
4) and issuing a control command, and putting high-level application functions into use. The function that is put in corresponds to the function that the master call quits.
The following describes the design of the above-described embodiments in conjunction with a preferred embodiment.
The implementation of switching between master and standby control rights of a network-level power dispatching system is shown in fig. 2 and 3, wherein keys for tool login, automation, dispatching control right exit and the like all have a verification right link:
1) the top left side of fig. 2, in the first combo box, shows whether the current system is a key.
2) The second combination box on the top of the left side of fig. 2 shows the automation control right, the scheduling control right and the total control right (system control right).
3) The third box on the top of the left side of fig. 2 shows the total control right (system control right) of the contralateral system.
4) The system critical application states are shown in the fourth combo box on the top left of fig. 2.
5) The AGC (automatic power control) and AVC (automatic voltage control) on the right side of fig. 2 refer to advanced application functions that issue control commands, and click-to-exit refers to exiting these functions. When the SCADA quits by clicking, the automatic control right quitting is prompted, the scheduling control right quitting is prompted, and the total control right quitting is prompted. Clicking to exit from the preposition, and carrying out channel locking control on the preposition.
6) Fig. 3 is a dispatch control exit dialog box providing a dispatch control status presentation and a drop button.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
