摘　　要：发电机励磁系统作为水电站的重要组成部分,主要用于对同步发电机的励磁绕组提供可调直流电压以及电流,其对于整个水电站的正常运行有着十分重要的影响。一旦发电机励磁系统发生故障,继电保护装置无法及时动作,将会对功率柜、励磁主回路以及转子绕组等设备造成严重的破坏,威胁水电站以及电力系统的安全运行,因此对水电站大电机励磁系统常见故障进行分析具有十分重要的意义。The generator excitation system,as an important component of hydropower stations,is mainly used to provide adjustable DC voltage and current to the excitation winding of synchronous generators,which has a significant impact on the normal operation of the entire hydropower station.Once the excitation system of the generator malfunctions,the relay protection device cannot act in a timely manner,which will cause serious damage to equipment such as the power cabinet,excitation main circuit,and rotor winding,threatening the safe operation of hydropower stations and power systems.Therefore,it is very important to analyze common faults in the large generator excitation system of hydropower stations.
