摘　　要：本文首先对输电线路距离保护原理进行了重新分类,接着给出了相量比较式距离继电器的核心思想,在补偿度为40%的输电线路上,以方向阻抗距离继电器和零序电抗型距离继电器为例,从理论上详细分析了串补电容安装在输电线路上不同位置,对相量比较式距离继电器造成的稳态影响,得出了串补电容安装在线路首端时对这两种相量比较式距离继电器无稳态影响、串补电容安装在线路中间时两种相量比较式距离继电器失效的结论。Firstly,this paper tells readers the core idea of Phasor-comparison distance relay,such as the compensation degree of 40% of the transmission line,this paper thoroughly analyses the steady effect of series compensation capacitor on Phasor-comparison distance relay when Series Capacitor is in different places of transmission line.This paper draws the conclusion that there is no effect on Phasor-comparison distance relay when Series Capacitor is at the front of the line,otherwise,phasor-comparison distance re...
