Abstract
This paper investigates the problem of fault location based on transient signals obtained at single-end of the transmission line. Current travelling waves are utilized to locate faults on transmission system. In this paper a review of different travelling wave methods in fault location is presented. The wavelet transforms is used for analyzing power system fault transients to determine the fault location and to provide time resolution for the high frequency components of the fault transients. These signals are decomposed into their modal components. The aerial and the ground mode. Wavelet transform is found to be an excellent tool for identifying the travelling wave reflections from the fault. Validation of fault location is carried out by ATP/EMTP simulations for typical 400 kV power system faults.
