220kV变电站防误系统改造设计

Design of the reformation of 220kV substation's anti-mistake defense system

220kV变电站无人值班改造对防误系统提出了新的要求,在分析目前变电站防误系统常用模式的基础上,以实际改造变电站为例,提出了适应原有运行习惯的变电站防误模式,并对防误系统通信功能改造、信息采集及操作闭锁功能的实现方法等做了详细的探讨,最后对电动隔离开关、断路器电气操作回路的联锁设计进行了讨论。

After 220kV substation supervision control to be reformed into integrated automation system, the new anti-mistake defense system is very important to meet operation requirement. Based on the analysis of the main kinds of anti-mistake defense systems which run in most substations now, an anti-mistake defense mode is brought forward. Then reformation of the anti-mistake defense system communication function with other intelligence device, information acquisition and new realization method of the anti-mistake defense system function are analyzed in detail. The design of electrical circuit defense system is discussed at last.
