摘要

兴安直流投运以来

直流滤波器发生多次电容器C1不平衡保护动作隔离直流滤波器事件。笔者总结近3年直流滤波器电容器C1不平衡保护动作情况

并对典型事件进行分析阐述

结合设备运行实际

提出相应的整改措施及建议

提高兴安直流工程直流滤波器安全稳定运行水平

并对未来的高压直流输电工程提供参考与借鉴。

Abstract

Since the operation of Xingan HVDC project

the DC filter isolation due to imbalance action of capacitor C1 occurred several times. In this paper

the imbalance protection action of DC filter capacitor C1 in recent three years are summarized

the typical event is analyzed

the corresponding correction measures and suggestions are proposed based on actual operation condition of the equipment so to improve the safe and stable operation level of DC filter capacitor for Xingan HVDC project and to provide reference for the HVDC transmission projects in the future.
