Transformer substation anti-misoperation system and method based on topology analysis

Abstract

The invention discloses a transformer substation anti-misoperation method based on topology analysis, and the method comprises the steps: building a power grid equipment topology model which comprisesa topology point model, a topology branch model and an adjacent matrix model, and generating a topology network according to the topology point model, the topology branch model and the adjacent matrix model; then, completing connection between any two nodes in the network based on a fast search algorithm; finally, carrying out initial analysis and dynamic tracking on the topological model, predicting the running state of the equipment after running, and judging whether misoperation occurs or not according to a prediction result. The invention further provides a transformer substation anti-misoperation system based on topology analysis. According to the invention, the topological model is analyzed and dynamically tracked to predict the operation state of the equipment after operation, so the operability of the equipment is automatically judged to meet the error-proofing requirement between the traditional station and the transformer substation.

Description

technical field [0001] The invention belongs to the technical field of electric power safety, and in particular relates to a method for preventing misoperation of a substation. Background technique [0002] With the continuous development of power grid technology, higher requirements are put forward for the safe operation of substations. In order to meet the safety requirements of substation maintenance control. The scheme of prior art is: [0003] A method of configuring independent five-defense equipment host computer is adopted for five-defense detection, so as to improve the accuracy of misoperation judgment. [0004] An auxiliary judgment method is proposed, which reduces the possibility of missed detection and misoperation by adding a switch operation with a logic locking function to the auxiliary equipment. [0005] In the computer monitoring system, the anti-error judgment in the operation of the whole station is realized through the five-proof monitoring module. ...

AI Technical Summary

Problems solved by technology

[0007] (1) The traditional logic blocking method is adopted, that is, software blocking logic or hardware electrical blocking logic is established in advance; however, since the integrity of the latch logic itself is also difficult to check, it is difficult to ensure the accuracy of these latch logics;

[0008] (2) In the centralized control mode, there is a lack of perfect means to prevent misoperation. At this time, the safety check module can only realize the error-proof inspection function of all equipment in the station, but cannot realize the error-proof inspection between stations
