And the resulted AC current on the DC side will have the similar frequency shift when transfers to the stator of the generator.
直流侧电流扰动反映到交流定子侧，也将发生频率偏移。
According to frequency characteristics of the stator current, which carries the fault information, there are two methods: Wavelet decomposition and spectral analysis.
针对定子电流特征频率所携带的故障信息，目前主要有两类处理方法：小波分解和频谱分析。
It is realized by adding a high frequency current to the original current of the stator and adding linear generator windings to magnetic pole.
