Description
Technical Field
[0001] The present invention belongs to the technical field of power grid dispatching, and in particular relates to a main grid dispatching switching operation network command system. Background Art
[0002] Electrical equipment is divided into three states: operation, standby, and maintenance. The process of changing the equipment from one state to another is called switching. By operating the disconnector, circuit breaker, and hanging or removing the grounding wire, the electrical equipment is changed from one state to another or the system changes its operating mode. This operation is called switching operation. The switching operation must comply with the operation ticket system and work supervision system.
[0003] Among them, the operation ticket refers to the written basis for electrical operations in the power system, including dispatching instruction tickets and substation operation tickets. In the specific implementation, first of all, the traditional main network dispatching still uses manual drafting to prepare a large number of main network operation tickets when issuing orders. Not only is the work efficiency low, but the manually drafted text operation tickets cannot accurately match the operation equipment objects, and are more dependent on the dispatching personnel's experience, which easily leads to errors in the writing of operation tickets. Secondly, the entire process of issuing orders still uses traditional manual methods such as telephones. Telephone orders not only have the risk of pronunciation deviation and distortion and disconnection of telephone audio transmission, but also consume manpower, and the personnel carrying capacity has reached its limit. Furthermore, with the rapid development of the power grid, the equipment involved in power dispatching is increasing, and the complexity is increasing, resulting in a gradual increase in the error rate of network dispatching orders, affecting the safety and reliability of power grid dispatching.
[0004] Therefore, in order to solve the above problems, it is necessary to develop a main network dispatching switching operation network command system. Summary of the Invention
[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a main grid dispatching switching operation network command system, which automatically generates operation tickets and performs simulation rehearsals, while setting up multiple safety and anti-error checks to ensure that network commands are efficient and accurate, and effectively improve the safety and reliability of power grid dispatching.

The alarm unit includes a key error alarm module and a verification error alarm module. The verification results in the result output unit include verification success, key error, and verification failure.
[0010] Among them, the post-operation remote status review system includes a monitoring camera unit connected to the target substation, an equipment status data acquisition unit based on the power SCADA system data, and an equipment status review unit. The current target substation monitoring screen is opened through the monitoring camera unit, the equipment status information after the operation is collected through the equipment status data acquisition unit, and re-checked through the equipment status review unit, and the verification ends after successful verification.

[0013] Furthermore, the operation ticket conversion module in the operation ticket drafting unit performs reasoning and conversion on the instruction ticket in combination with the real-time section of the power grid, the topology of the power grid and the rules of the system knowledge base.
[0014] Furthermore, the operation ticket drafting unit establishes an operation ticket database based on the real-time operation data of the power grid in the EMS system.
[0015] Furthermore, the simulation rehearsal unit forms a constraint guidance mechanism for the correctness of the operation sequence in the operation ticket through the real-time section of the power grid, the power grid topology structure and the power grid equipment operation rules.
[0016] Furthermore, the rehearsal mode of the simulation rehearsal unit includes automatic rehearsal and manual rehearsal, wherein the automatic rehearsal is that the system automatically selects all operation instructions for a one-time simulation rehearsal, and the manual rehearsal is that the user manually operates the rehearsal, executes the operation instructions step by step, or selects the first n steps of the operation instructions for rehearsal, where n = 1, 2, 3...
