Discrete Wavelet Transform Based Technique to Locate Faults in Three Terminal Transmission Lines
This paper proposes a discrete wavelet transform based technique to locate faults in three terminal transmission lines. The proposed technique establishes the location of faults by utilizing current signals of both end of transmission line. The current signals are processed using discrete wavelet transform toolbox of MATLAB. The proposed transmission line fault location technique is not affected by varying location of faults and type of fault. Extensive simulation studies carried out using MATLAB/Simulink exemplifies the effectiveness of the proposed discrete wavelet transform based fault location technique.
