基于PLC的电气配电柜自动控制系统研究

Research on Automatic Control System of Electric Power Distribution Cabinet Based on PLC

本文基于PLC实现了配电柜及其连接线路上短路故障的监测、定位和切除。通过监测配电柜的绝缘电阻实现了对配电柜的绝缘智能监控和异常报警,通过故障定位模块实现了对故障位置的快速定位,并通过PLC控制将故障线路及时切除,保证了配电系统的正常运行。

This paper realizes the monitoring,location and removal of short-circuit faults on the power distribution cabinet and its connecting lines based on PLC.Through monitoring the insulation resistance of the power distribution cabinet,the insulation intelligent monitoring and abnormal alarm of the power distribution cabinet are realized,and the fault location is quickly located through the fault location module,and the fault line is cut off in time through the PLC control to ensure the power distribution system Normal operation.
