摘要

兴仁换流站563交流滤波器2011年2月发生了一起不平衡保护跳闸事故

此次跳闸事故在以往的直流工程中较为罕见。文章就此次事故介绍了电容器的接线方式、不平衡保护的基本原理

深入分析了此次故障的根本原因

提出了相应的解决办法和运行维护建议。对交流滤波器的设计和运行维护具有一定的参考价值。

Abstract

The trip of 563 AC filter at Xingren converter station is happened due to unbalance current protection in February 2011

which is uncommon in DC projects in the past.In this paper

wiring mode of the capacitors and basic principle on the unbalance current protection are introduced in the combination with the fault

the root causes of the accident is analyzed deeply and the corresponding solutions as well as operation & maintenance suggestions are proposed

which have a significant reference to the design

operation & maintenance of AC Filter.
