Fault analysis of wind generator connected power system using wavelet technique

This paper presents an approach to analyze the faults that occur on transmission line and identify the instant of fault, by using Wavelet transform technique. The experiments performed for different kinds of faults on transmission line have proved to be accurate for analyzing the type of fault. Section 1 in this paper shows different ways to integrate wind generator to the feeder and observe the short circuit current wave form for different types of integration, which will be used in setting the fault current value in the relay for protecting the grid connected to the wind generator. In this paper Wavelet transform technique is used to identify and classify the faults quickly. The simulation was carried out in MATLAB/SIMULINK environment.
