Design of Direct Current Power Supply Operation Status Monitoring System for Substation Based on PLC Technology
To enhance the reliability of the direct current power supply system in substations,this paper proposes a design scheme for an operation status monitoring system based on Programmable Logic Controller(PLC)technology.The system employs high-precision sensors and high-performance PLC for data acquisition and processing,and realizes fault diagnosis and remote control through a human-machine interface and communication modules.Experimental results show that the system can quickly detect and accurately locate fault sources under various fault conditions,with an average fault detection time of less than 20 ms and a positioning accuracy exceeding 95%.This indicates that the designed system can effectively ensure the stable operation of substations.
