摘要
变电站直流系统是保障电网安全稳定运行的重要组成部分,其绝缘性对电力系统的可靠性具有重要作用.但是,在实际运行过程中,变电站直流系统绝缘接地故障时有发生,严重威胁着电力系统的安全.文章简要阐述变电站直流系统的构成,分析绝缘接地故障的类型与危害,探讨常见的几种检测方法的应用,并结合实际案例分析绝缘接地故障的处理.
Abstract
The substation direct current system is an important part to ensure the safe and stable operation of the power grid,and its insulation plays a crucial role in maintaining the reliability of the power system.But in the actual operation process,the substation direct current system insulation grounding fault often occurs,which brings serious threat to the safe operation of the power system.The article briefly describes the composition of the substation DC system,analyzes the types and hazards of insulation grounding faults,discusses the application of several common detection methods,and analyzes the treatment of insulation grounding faults combined with actual cases.
