一种变电站五防逻辑自动生成及校验方法

Automatic Generation and Verification Method of Substation Five-Prevention Logic

基于对变电站五防逻辑的仔细分析,对五防逻辑库数据进行提取分析,提取锁号生成间隔,给出了变电站五防逻辑的自动生成方法,并应用原五防逻辑数据库与生成的五防逻辑数据库进行对比分析,得到校验报告和正确的五防逻辑表。该方法能够通过给定的逻辑数据库,分析变电站一次接线方式,通过软件实现判定设备类型,并判断开关、闸刀开关、接地刀等设备的五防闭锁逻辑。该方法生成的五防逻辑具有较高的准确性,五防系统的修改和维护工作量也因此而大大减少。

Based on the careful analysis of the five prevention logic,this paper extracts and analyzes the data of the five prevention logic library,extracts the lock number generation interval,proposes an automatic generation method of the five prevention logic in the substation,and compares the original five prevention logic database with the five prevention logic database generated to obtain a verification report and a correct five prevention logic table.This method can analyze the primary wiring mode of the substation through the given logic database,judge the equipment type through software,and judge the five prevention locking logic of switches,knife switch,grounding knife and other equipment.The five prevention logic generated by this method has high accuracy,and the workload of modification and maintenance of the five prevention system is greatly reduced.
