摘要

为限制短路电流

在220 k V线路上加装串联电抗器。本文以新疆220 k V宜化电厂出线侧加装限流电抗器工程为背景

利用电磁仿真软件EMTPE

通过对加装串抗前后本线路以及下一级线路的过电压情况对比分析

发现220 k V线路串联电抗器对线路工频过电压、潜供电流和恢复电压、合闸操作过电压以及对线路断路器瞬态恢复电压有一定的影响。

Abstract

Series reactor is installed in the 220 k V transmission line so to limit short circuit current.In this paper

the addition of current limiting reactor at the outgoing side of Yihua 220 k V power plant in Xinjiang is taken as the background.It is found by the use of electromagnetic simulation software EMTPE and through voltage analysis of the transmission line and next level line before and after the installation of the reactor that the series reactor of 220 k V transmission line has a definite influence on the power frequency voltage of the line

secondary-arc currents and recovery voltages

reclosing overvoltage in the closing operation as well as transient recovery voltage of circuit breaker of the line.
