Abstract: Based on SCADA online monitoring system, the real-time vibration data of the main bearing were obtained. The fault characteristics were extracted by wavelet packet and the collection of empirical modal decomposition model. The impact signal of the time domain diagram, the spectrogram of the fault characteristics of the frequency spectrum, the envelope spectrum of the fault frequency amplitude and the harmonic signal multiples were analyzed. The fault location and the severity of the fault were determined. The severity of the fault, to realize the main bearing fault early warning, The method was provided assistance for efficient maintenance for the wind farm operation and maintenance personnel, and was
reduced operation and maintenance costs.
