摘　　要：根据高坝洲电厂励磁系统的主要组成部分及其工作原理,统计、分析了发电IAEC-2000型自并励励磁系统历年总故障现象,电厂励磁装置出现"励磁系统总故障"、"励磁调节器双机切换"告警的原因系脉冲检测电路出现系统电压异常,屏蔽自身"本机正常"造成通道切换。励磁总故障原因的确认为运维人员进行励磁事故处理提供了依据。According to the main components and working principles of the excitation system in Gaobazhou Hydropower Station, statistics and analysis of the excitation system faults encountered over the years are carried out. The results show that the general fault warning or the double switch warning of excitation regulator are caused by the abnormal system volt- age in the pulse detection circuit which blocks the system normal signal and leads to the channel switching. It could be useful reference to the treatment of excitation system fault for the maintenance personnel.
