Abstract

This paper presents a novel fault location algorithm for series compensated transmission lines, which utilizes samples taken in just one terminal from voltage transients generated by fault clearing action of circuit breaker. In this algorithm, using wavelet transform, first and second inceptions of voltage traveling wave to the fault locator are detected and then actual wave speed is determined without any need to the line parameters and precise fault location is calculated. Because of using only one terminal data, algorithm does not need to communication equipments and data synchronization. Due to calculating of wave speed independent of line parameters, accuracy of algorithm is not affected by aging, change of climate and temperature, which modify wave speed. Fault resistance, fault inception angle and fault distance does not affect accuracy of the method. Extent simulations carried out with SimPowerSystem toolbox of MATLAB; confirm capability and high accuracy of the proposed algorithm.
