Abstract

Abstract: This paper proposes a new algorithm to detect and classify faults in the electric power transmission line. Transmission line protection is an important issue in power system engineering because 85-87% of power system faults are occurring in transmission lines. This paper presents a technique to detect and classify the different shunt faults on transmission lines for quick and reliable operation of protection schemes. Discrimination among different types of faults on the transmission lines is achieved by the application of evolutionary programming tools. Further, fault signal data are imported into MATLAB for postprocessing, and time-frequency analysis using Signal Processing Toolbox in MATLAB.
