摘要：
In this paper we studied the fault feature of the generator set and the characteristics of wavelet packet theory for signal de noising. The vibration signal of the generator set in different states is analyzed by using the signal re construction technique of the wavelet packet theory. The time domain method is given for the generator set fault diagnosis. The experiment results show that the wavelet packet theory can be used to directly identify the state of the generator set and provide a credible new idea for complex machinery fault diagnosis.
