摘　　要：广东粤电云河发电有限公司#1发电机无功功率多次出现异常摆动,指出了引起发电机无功功率摆动的因素,通过分析,最终确定#1发电机无功功率摆动的主要原因是发电机励磁系统的励磁电压互感器存在暂态性故障,更换#1发电机的励磁电压互感器后,无功功率摆动现象消失。The reactive power of generator No.1 of Guangdong Yudean Yunhe Power Generation Company Limited fluctuated abnormally multiple times.The factors leading the reactive power of the generator to fluctuate were pointed out.According to analysis,it was decided finally that the main reason of the reactive power fluctuation of the generator No.1 is transient fault of the excitation voltage transformer of the generator excitation system.The excitation voltage transformer of the generator No.1 had been replaced,and the fault of reactive power fluctuation was eliminated.
