变电站直流系统监控及故障诊断技术分析

Analysis of DC System Monitoring and Fault Diagnosis in Substation

直流系统是变电站的重要组成部分。变电站中的保护设备和通信设备均需直流供电。如果变电站的直流系统出现故障,则会引起变电站二次系统出现大范围故障,影响变电站的安全稳定运行。研究开发变电站直流系统的监控技术和故障诊断系统,有利于强化变电站直流系统的运维和安全管控。

In substation,direct current system is an important part,many protection equipment and communication equipment need to rely on direct current power supply.If the direct current system of the substation fails,it may cause a large range of problems in the secondary system of the substation,and bring great risks to the safe and stable operation of the substation.Therefore,this paper introduces the monitoring technology of substation direct current system in detail,and introduces the development of substation direct current fault diagnosis system,which has certain value and significance for strengthening the operation and maintenance safety management and control of substation direct current system.
