兴仁换流站交流滤波器开关POW装置运行情况分析

Operation Analysis for POW Device of AC Filter Switch at Xingren Converter Station

由于换流器在换流的时候需要消耗大量的无功,兴仁换流站配置了10组滤波器,用于承担无功补偿与滤除谐波。为减少涌流和暂态过程,在控制断路器的时候,还专门为滤波器小组断路器安装了特别的合闸角检测装置POW。文章介绍了POW装置的合闸工作原理、控制策略,结合兴仁换流站至2007年投运以来POW装置出现的多种故障,分析了POW装置出现故障的原因,并对POW装置的运行维护提出了建议。

Since a large amount 10 panel filters are installed in of reactive power consumption by the converter at the time of convertion, Xingren converter station for the purpose of reactive power compensation and harmonic filtering. In order to reduce the inrush current and transients, the special closing angle detection device POW is installed at the circuit breaker of panel filter during the control period of circuit breaker.In this paper, the closing operation principle and the control strategy of the POW are introduced, the fault causes of the POW are analyzed since operation from 2007 at Xingren converter station and the suggestions on operation and maintenance of the POW device are proposed.
