摘要

对于扰动清除以后

以往人们只是关心故障清除后系统的摆动过程和系统的稳定性

很少考虑摆动过程中线路以及线路上保护对于系统暂态影响的情况

所以分析电力系统保护脆弱性是非常重要的。文中在对电力系统保留结构模型的暂态能量研究的基础上

提出了一种基于支路势能分析电力系统线路脆弱性的新方法。

Abstract

After cleaning the disturbance

the process of the post-fault system swing and the stability was mainly concerned and the influence of swing lines and the line protection on system transient was ignored.Therefore

it is important to detect the weak line protection of power system.After studying on the potential energy based on the structure preserving model

the paper presented a new method to analyze the line protection weakness of power system based on branch transient potential energy method.
