Protection Scheme For Double Circuit Transmission Lines Based On Wavelet Transform

In this paper, a wavelet transform based technique is introduced to detect and classify shunt faults in a double circuit transmission line which uses single end fault current data only. Simulation studies have been carried out on a double circuit transmission line test system using MATLAB for justification of the proposed technique. The simulation results of the proposed technique show that wavelet transform based proposed scheme correctly detects and classifies the shunt faults.
