交流滤波器电容器运行情况分析及共性问题探讨

Operation Analysis and Discussion of General Common Problems of AC Filter Capacitor

对宝安换流站两起典型的交流滤波器电容器不平衡保护跳闸进行了深入的分析,通过对故障电容器的解剖,研究电容器内部故障的发展过程。并对宝安换流站自投运以来所有电容器跳闸进行统计分析,总结出交流滤波器电容器运行过程中遇到共性问题,从运行维护的实际出发,提出改进建议,对交流滤波器的设计和运行维护具有一定的参考价值。

In this paper, two typical imbalance protection trips of AC filter capacitor at Baoan con- verter station are analyzed in detail. The development process of internal fault is investigated through disassembly of the fault capacitor. And the tripping of all capacitor since putting into service at Baoan converter station is statically analyzed, the general problems of AC filter capacitor encountered dur- ing operation period are summarized. The improvement suggestions based on operation and mainte- nance are presented, which has a definite reference to the design and maintenance of AC filter.
