摘　　要：对鱼米滩水电站 1号发电机组空载启动时出现的定子绕组过电压故障进行了分析 ,指出高次谐波谐振是导致过电压的主要原因 。The stator winding over voltage fault of generator #1 in Yumitan hydroelectric power station under no load starting is analysed in the paper. It is pointed out that the over voltage fault is the result of high order harmonic resonance. The methods and measures should be taken are presented.
