【摘要】 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。更多还原

【Abstract】 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.更多还原
