Research on Online Monitoring of Gear Fault of Wind Power Gearbox Based on Undecimated Wavelet Transformation
According to fault characteristics of wind turbine gearbox, an On-line Monitoring System of wind turbine gearbox based on the undecimated discrete wavelet transformation was developed. Measured the vibration signal of gear fault in the laboratory, The signal after undecimated wavelet transformation can be more accurate and clear display characteristics, which was conducive to diagnose gear failure quickly and effectively.
