Faulted Phase Selection Based on Wavelet Analysis of Traveling Waves

V. S. Kale, S. R. Bhide, and P. P. Bedekar

Abstract—Accurate faulted phase selection is critical to avoid tripping of the incorrect phase or unnecessary three phase tripping. Moreover, an associated requirement of faulted phase selectors is high-speed operation, since the selection process must be completed in the immediate post-fault period before breaker opening. This paper presents a novel scheme for selecting a faulted phase on transmission line based on the traveling wave theory, meeting both the requirements of accuracy and speed. The proposed approach uses the mathematical tool of wavelet modulus maxima to solve the problem. MATLAB/ Simulink software was used to test the proposed faulted phase selection approach. Various fault conditions were simulated by varying fault type, fault resistance, fault location and fault inception angle, on a given power system model. The simulation results demonstrate the validity of the proposed approach of faulted phase selection.

Index Terms—Faulted phase selection, traveling wave,wavelet modulus maxima, transmission line.
