Adopt one kind of design plan that PLC controls in the protection the main body of a book has been introduced succeeding an electricity in electric system, that capital is designed time is that the KV circuit imports 10 mainly , change into 380 V voltage grades, before the PLC front and back add front to passage and the queen to passage, change before to passage middle course electric current , voltage a train of, the wave filtering the general is exchanged changing waking up with a start for direct-current, the entering carrying out comparison and switch amounts again , controlling conducting entering PLC, by PLC, The malfunction signal is shown out by lamp light or the alarm signal.

本文介绍了在电力系统继电保护中采用PLC控制的一种设计方案，本次设计主要是将10KV线路输入，转化为380V电压等级，在PLC前后加入前向通道和后向通道，在前向通道中经过一系列的电流、电压转换，将交流转换为直流，进行滤波，再进行比较和开关量的输入，传入PLC，通过PLC的控制，将故障信号通过灯光或者报警信号表现出来。
