摘要

电容器由于结构、接线方式的不同

其内部故障保护的配置和整定存在较大的差别。文章从某变电站35 kV电容器群爆入手

根据发生后的现场记录、故障后的电气试验结果、电容器现场安装情况

并利用PSCAD对故障过程进行了仿真分析和故障重现

通过对事故原因的分析和讨论

吸取了此次事故的教训

提出了一些改进建议

希望能够为今后运行提供参考。

Abstract

The capacitor

due to different structure and wiring mode

has big difference in its disposition and setting of the internal protection.Starting with external fuse group explosion of 35 kV capacitor at certain substation;based on PSCAD

the fault process is simulated and analyzed and fault reproduction is made according to site record

electrical test result and installation of capacitor after the fault.The lesson on the fault is summarized through analysis and discussion of the fault

and some improvement suggestions are proposed so to provide reference for the future operation.
