110kV变电站防误设计探讨

Discussion on the Design of Anti-mistake Defense System of 110 kV Substation

防误闭锁装置是变电站重要的组成部分之一。文中介绍了机械程序锁、电气闭锁、微机五防系统和"逻辑闭锁+电气闭锁"防误闭锁方式,分析了各自的特点及实现方法,指出应该根据变电站具体情况、管理方式等多方面的因素来选用不同的防误闭锁方式。最后给出了各类变电站的五防设计方案。

Anti-mistake defense device is one of the most important parts of substation.In the paper,the mechanical procedure lock,electrical atresia,the microcomputer-based program anti-mistake defense system and the logic atresia and electrical atresia were introduced.And their characteristics and realization methods were analyzed respectively.It is pointed out that the factors such as substation situations and management mode should be taken into consideration for the anti-mistake defense system selection.At last,the microcomputer-based program anti-mistake defense systems for substations were presented.
