Abstract：It is difficult to extract the characteristics of fault signals of large-scale wind turbine main bearing because it is complex with strong non-linearity, strong coupling and time-varying.Multi-fractal theory is put for-ward to detect and recognize the different faults of the main bearing .And the method is intuitive and sensitive to diverse faults of large-scale wind turbine main bearing .The results of experiments on the main bearings of 1.5 MW wind turbines are reported to demonstrate the method is quick and effective .
