摘　　要：针对某电厂一次机组掉闸故障中事故总信号和开关变位信号的事件顺序记录遥信异常情况,经检查NCS系统,认为时钟系统在设计和设置方面的问题是信号异常的主要原因,提出关闭RCS-9698G下发时间功能,并增加IRIG-B码对时方式、关闭无用的对时源等措施及建议。Aimed at these abnormal Remote Signals of Sequence Of Event(SOE)of general fault signal and switch signal in a generator malfunction of power plant,the erroneous designing and setting of timing system are main reasons after thorough inspection and analyzing.The settlements including shutting up timing function of RCS-9698 G,adding IRIG-B timing and blanking out ex-service timing source are proposed.
