Fault Detection and Classification in Transmission Lines based on Wavelet Transform

Abhjit Jadhav, Kawita Thakur

Abstract: In the paper, a novel wavelet transform based fault detection and classification technique is studied. The technique involves analysis of fault induced transient that can provide extensive information about the fault detection, classification, fault type, location and fault duration. These fault transients with system voltage and current can be effectively analyzed with the wavelet transform technique. In MATLAB simulink, two bus systems with various fault condition and their combination are simulated. The two bus system is also tested for various fault location. The simulation results indicate that the wavelet transform is an effective technique in the field of fault detection and classification of various fault categories.
