Description
Technical Field
The application relates to the technical field of power grids, in particular to a method, a device, equipment and a medium for one-key sequence control simulation test of a transformer substation.
Background
Since the intelligent substation is built, the substation monitoring system deploys a sequential control operation function so as to improve the operation efficiency and safety of the substation equipment. The network company started in 2017 promotes the technical improvement and application of the one-key sequential control function of the intelligent transformer substation, so that the centralized monitoring operation level of the unattended transformer substation is improved. The realization of a one-key sequential control function relates to the technologies of a sequential control module of a transformer substation monitoring system, an intelligent five-prevention device, a view screen linkage system, a 'double confirmation' sensing judgment mechanism and the like. More importantly, one-key sequential control function debugging needs one-time equipment linkage, and for operating the transformer substation, power failure needs to be arranged one by one at intervals, which is difficult to solve in the current power grid operation mode. When an intelligent substation is newly built, all the total stations can carry out actual operation, sequence control ticket verification is not difficult, once interval extension is carried out, due to the fact that extension interval bus knife switches are safety measure associated knife switches, operation of a failure receiving pressing plate and an original interval protecting pressing plate in bus differential protection is carried out in extension interval secondary operation tickets, operation of extension intervals is added to the bus operation tickets, a plurality of obstacles exist in sequence control ticket verification, and the sequence control ticket verification can be carried out only by adopting a complex power failure mode. In fact, due to the fact that the power failure mode is difficult to arrange, sequential control verification cannot be conducted on part of intervals. Therefore, it is necessary to research the debugging mode of the one-key sequence control function under the condition of no power failure, and the method will play a key role in promoting the application of the one-key sequence control function.
However, at present, the communication capability of the substation is mainly simulated through simulation equipment in a one-key sequence control function debugging mode, and a simulation test only simulating the communication capability of the substation greatly differs from an actual one-key sequence control operation environment in a simulation environment, so that the accuracy of a one-key sequence control verification result is greatly influenced.
Therefore, how to solve the above problems is a problem that needs to be solved at present.
