Abstract

A new technique of phase to phase fault detection and faulty phase(s) identification of the series capacitor compensated six phase transmission line is proposed by the use of Wavelet Transform (WT) scheme. Furthermore, the wavelet norm based on the wavelet detail coefficients information on all the phases is used to detect the phase to phase faults. Six phase current signals are processed using wavelet transform, so that the produced norm by the high frequency detail coefficients of wavelet transform at level-1 is analyzed and a wavelet norm threshold is also proposed. Simulation studies are carried out in MATLAB, for various phases to phase faults, for numerous cases of fault parameters variation situations. The simulation results signify the appropriateness of the proposed technique and the flexibility of varying scheme circumstances.
