摘　　要：换流站交流滤波器一般配置选相分合闸装置,而选相分合闸装置出现故障,会造成滤波器投入失败或引起直流输电系统换相失败。提出一种交流滤波器选相分合闸状态监视的方法,对滤波器投入时刻的断路器合闸顺序和流过滤波器组的电流进行监视,提前预判选相分合闸装置的不正常运行状态。该监视方法基于故障录波文件,可靠性高,实现方便。The AC filters in converter station is generally equipped with phase-selection switching devices.The fault of phase-selection switching devices may causes the closing failure of AC filters or the commutation failure of DC transmission system.A method for monitoring the phase selection opening and closing status of AC filter is proposed,which monitors the closing sequence of circuit breaker and the current flowing through the filter bank at the time when the filter is put into operation.The device can pre judge the abnormal operation state of the phase selection opening and closing device in advance.The monitoring method is based on the fault recording file,with high reliability and ease of implementation.
