摘　　要：励磁系统误强励对发电机本体、励磁系统及电网安全稳定运行都具有极大的危害,本文对自并励励磁系统空载及负载情况下误强励的影响进行介绍,对高温气冷堆核电站示范工程在最严重的空载误强励情况下的灭磁能力及发电机过电压保护进行了分析,建议修改发电机过电压保护出口方式及增设发电机空载过电压保护,可有效防止励磁系统误强励而造成的设备损坏。Excitation system abnormal forcing will bring great harm to the safe and stable operation of the generator body,excitation system and power grid.This paper introduces the influence of excitation system abnormal forcing under no-load and load conditions of potential source static excitation system,and analyzes the de-excitation capability and generator overvoltage protection of high temperature gascooled reactor nuclear power plant demonstration project under the most serious no-load excitation system abnormal forcing.It is suggested to modify the outlet method of generator overvoltage protection and add generator no-load overvoltage protection,which can effectively prevent equipment damage caused by excitation system abnormal forcing in the process of starting and stopping.
