Abstract :
According to fault characteristics of wind turbine gearbox, a wind turbine gearbox fault diagnosis method based on the undecimated discrete wavelet transformation of lifting scheme was proposed. With the test of the vibration signal of gear fault in the laboratory, the results showed that this (proposed) method can diagnose wind turbine gearbox faults more effectively than the traditional wavelet transformation.
