同步发电机转子绕组匝间短路故障的谐波传递分析

Analysis of Harmonics Transmit by Rotor Winding Inter-turn Short Circuit Fault in the Synchronous Generator

同步发电机转子绕组匝间短路时,它产生的谐波可以传递到励磁机励磁绕组。通过仿真试验表明,该谐波传递到励磁机定子绕组时,其幅值的衰减程度与发电机转子绕组上感应电动势谐波频率有关,频率越高衰减程度越高。

Against the fault of rotor winding inter-turn short circuit on synchronous generator,analysis was done in harmonics transmit from rotor wingding to exciter excitation wingding.Based on the simulation test of harmonics transmit,came the conclusion that its degree of decay varied with the frequency of harmonics on rotor wingding,the higher the frequeney the greater the decay degree.
