PLC在两路供电系统中的应用

Application of PLC in Two Way Power Supply System

介绍了可编程序控制器（以下简称ＰＬＣ）在两路供电系统中控制联络断路器自动投入的一种有别于传统继电器控制的新方法。通过ＰＬＣ实现对联络断路器在正常运行状态、事故欠压和事故短路状态下的监测与控制。

A new control method of PLC, which is different from conventional relay control, is introduced. The interconnection breaker monitoring is made by PLC to ensure safety and reliability in power supply.
