Abstract

Fault diagnosis of DFIG is a prominent challenge in wind turbine condition monitoring. Many machine
learning algorithms have been applied to DFIG fault diagnosis. However, these current machine learning algorithms
failed to give satisfactory fault diagnosis results due to some of their drawbacks. This paper presents a wavelet
transform and support vector machine (SVM) technique based algorithm for fault diagnosis of DFIG. The SVM is
used to extract the information from a signal over a wide range of frequencies. This analysis is performed in both time
and frequency domains. Experimental results are validated by using MATLAB.
