An electric power five-proof intelligent logic verification system and method

Abstract

The invention relates to an intelligent logic verification system and method of power five-prevention, and belongs to the field of power system operation. The system comprises an input unit, a storageunit, a checking unit and an output unit, the input unit is used to log in a historical operation ticket or input a new operation sequence, and establishes an initial operation ticket model; the storage unit stores the historical operation ticket and a new operation ticket, and uses the stored operation tickets as a simulation test sample; the checking unit comprises forward and backward checkingunits, the forward checking unit carries out forward simulation operation of the operation sequence of the operation ticket, checks whether the anti-error logic of the forward operation of the operation ticket is correct, and if YES, the next unit is entered; the backward checking unit carries out backward disordered simulation operation on the operation sequence of the operation ticket, and checks whether the anti-error logic can pass, and if NO, the next unit is entered; and the output unit generates an operation ticket from the initial operation ticket model that passes checking, and stores the generated operation ticket in the storage unit synchronously.

Description

technical field [0001] The present invention relates to the field of power system operation, and more specifically, to an electric power five-defense intelligent logic verification system and method. Background technique [0002] Under the management mode of integrated operation and maintenance of substations, there are many substations under the jurisdiction of the team, the workload of operation and maintenance is heavy, and the shortage of human resources is a common problem in all teams. Checking the correctness of the error prevention logic data is one of the periodic tasks of the current operation and maintenance team. Every time you check whether the error prevention logic of a substation is correct, you need to check line by line. At the same time, you need to simulate the operation of each device to verify the error prevention logic. correctness. Since some special scenarios are easy to miss, and reverse verification cannot be performed, the five-defense logic erro...

AI Technical Summary

Problems solved by technology

Because some special scenarios are easy to miss, and reverse verification cannot be performed, the five-proof logic error inspection is not comprehensive, and the errors cannot be fully checked out.

[0003] In addition, the anti-error logic is manually edited and regularly checked by operation and maintenance personnel. The logic formula is lengthy, and it is difficult to ensure its correctness only by manual maintenance. The logic implies omissions or errors, which may easily cause substation misoperation accidents

Moreover, some entries in the logic formula must be modified during the expansion and transformation of the substation, so there are many versions of the anti-mistake logic, which is easy to cause confusion
