摘要：
In this paper, according to the bearing current signal is nonstationary and nonlinear characteristics, establish of doubly fed wind turbine simulation model and test bench, respectively under the normal and fault condition of bearing of motor current signal by EMD processing and analysis. Through the simulation analysis and experimental verification, it shows that after the EMD decomposition of the IMF component can effectively isolate the fault information in the current signal. EMD is an effective method of current signal processing.
