一起110kV末端线路单相接地故障分析

摘要

With the development of science and technology, the requirements for reliability on various kinds of manufacturing equipments and living electric apparatus grows higher and higher, the operation mode and protection coordination of power grid has been paid more and more attention. Combining with an actual case, the article analyzed of a single phase grounding fault for 110kV terminal transmission line with the Matlab, and put forward some suggestions on protection coordination of terminal transformer substation.%随着科技的发展，各种生产设备和生活电器对供电电源的可靠性要求越来越高，电网运行方式和保护配合问题得到重视。本文结合一起110kV末端线路单相接地故障案例，运用Matlab仿真工具，深入分析了110kV电网末端线路单相接地故障现象，对末端站的保护配合提出建议。
