Application of DWt for identifying type of fault occurred in wind turbine system

This paper proposes a technique to identify the fault type in the wind turbine system using Discrete Wavelet Transforms (DWT). The fault signals are simulated using PSCAD/EMTDC. The comparisons of the coefficients DWT have been performed in order to classify fault types. The results are shown that the algorithm is capable of performing the fault location as well as the fault types with satisfactory accuracy.
