500kV综合自动化变电站的防误闭锁应用

防误闭锁装置是变电站重要的组成部分之一。阐述了变电站对防误闭锁装置的基本要求,分析了传统防误闭锁装置的特点,并针对其不足之处,重点介绍了利用综合自动化装置实现变电站防误闭锁系统的实施方案。通过以运行中的500 kV张家港变电站为例,证明综合自动化防误闭锁系统在各种可能操作方式下都能实现可靠的防误闭锁功能,同时也提出了其不足之处和需要改进的地方。

Application of mistake proof and lock installation in 500 kV comprehensive automatic substation

Mistake proof and lock installation is one of the most important parts of substations.This paper describes the essential request on mistake proof and lock installations.Through analyzing the traits of the traditional installations,it proposes the ways of using comprehensive automatic installation to implement mistake proof and lock.And the successful using in 500kV Zhangjiagang substation proves that the system can work well in different conditions.At last,it gives some improvement measures.
