摘要

滤波器组作为换流站的无功补偿设备和滤波装置

在电网的安全运行中起着非常重要的作用。目前滤波器组用断路器在实际运行过程中因重燃等原因导致的故障时有发生

本文针对一起特高压换流站滤波器组用断路器反复重燃导致电容器组放电的故障进行分析

通过故障录波、仿真等手段

分析冲击电流对电容器组不平衡电流的影响

并提出了预防电容器组放电的相关建议。

Abstract

The filter bank

as the reactive compensation device and filter device of converter station

playsa very important role in safe operation of power grid. At present

the fault of circuit breaker for the filterbank in the actual operation due to such reasons as reignition etc is occasionally happened. In this paper

the fault of capacitor bank discharge due to repeated reignition of circuit breaker for the filter bank at oneUHV converter station is analyzed to analyze the influence of impulse current on the unbalance current ofcapacitor bank through such means as fault recording and simulation

and related suggestion on preventingcapacitor bank from discharging is proposed.
