一种变电站高压断路器软件计数器

A Software Counter for High-voltage Circuit Breakers in Substations

针对运维人员统计变电站断路器跳闸次数繁琐的问题,设计了一种软件计数器。该计数器从后台监控机历史数据库中获取每台断路器跳闸记录,实时对每台断路器的所有跳闸进行记录、计算、累加,并将累加值映射到监控后台机实时库遥测表中,由实时库实时更新每个高压断路器跳闸总次数,然后通过画面编辑呈现到监控运行画面、调度端和SVG系统,从而可在后台监控机、调度端和办公电脑实时查看断路器跳闸次数。

A software counter is designed to address the cumbersome issue of counting the number of trips of substation circuit breakers by operation and maintenance personnel.This counter retrieves the tripping records of each circuit breaker from the background monitoring machine's historical database,calculates and accumulates all tripping record of each circuit breaker in real-time,and mapps the accumulated values the real-time database telemetry table of the monitoring backend machine.Real time library updates the total number of trips for each high-voltage circuit breaker in real-time,afterwards,it will be presented to the monitoring operation screen,scheduling end,and SVG system through screen editing.Therefore the number of circuit breaker trips can be viewed in real-time on backend monitoring machines,dispatch stations,and office computers.
