A graphical expression method of intelligent substation anti-mislocking logic

Abstract

The present invention provides a graphical expression method of anti-mislocking logic in intelligent substations. The method includes the following steps: (1) progressively loading interlocking rule files, and scanning the content of the rules line by line; (2) generating an anti-mislocking logic tree ; (3) Transform the interlocking logical relationship into a topological connection; (4) Graphically express the interlocking logical relationship. The present invention realizes the visualization of the anti-mislocking logic of the intelligent substation, improves the efficiency of reading and viewing the anti-mis-locking logic, is beneficial to save the time-consuming labor cost of debugging, and ensures the correctness of the anti-mis-locking logic.

Description

technical field [0001] The invention relates to a graphical expression method of an intelligent substation, in particular to a graphical expression method of an intelligent substation anti-mislocking logic. Background technique [0002] Smart substations are an important part of the construction of smart grids. Up to now, more than 1,000 smart substations have been built and put into operation by State Grid Corporation of China. In order to prevent misoperation, the five-prevention operating procedures of the substation are stipulated, that is, to prevent the wrong opening and closing of the circuit breaker, to prevent the load opening and closing of the isolating switch, to prevent the live connection (closing) of the grounding wire (grounding switch), and to prevent the grounding wire ( Grounding switch) combined with circuit breaker (isolating switch) to prevent accidental entry into the charged interval. , the five defenses at the interval layer are realized by the meas...

AI Technical Summary

Problems solved by technology

It mainly solves the problem of time-consuming and low efficiency of manual configuration of five-proof interlocking blocking rules

[0007] In summary, research has been carried out on anti-mis-locking and visualization of smart substations. The focus of the research is automatic generation of anti-mis-locking logic rules, smart substation interval and multi-interval anti-mis-locking, smart substation SCD file virtual loop visualization scheme, etc. , but there is no graphical expression method for the interlocking logic relationship of smart substations
