Fault Diagnosis Technology for Power Electronics Rectifier Based on Wavelet Packet

Abstract:

Article Preview

The paper presents on power electronics controlled rectifier faults diagnose technology based on the combination wavelet packet transformation and neural network mainly. By using the character of wavelet packet multiresolution, fault signal is decomposed at multi-scale, orthogonalation and normalization, extract feature vector, which as training input of neural network, and design classifier of fault pattern. The validity and feasibility of the fault diagnosis method is demonstrated by simulation. this method can quite accurately diagnosis fault and define fault element for power electronics controlled rectifier, and the diagnosis precision is high, the method has very good practical value and apply future on solving power electronics controlled rectifier fault diagnosis.
