Fault location algorithms for high-voltage transmission lines

Abstract

This paper studied method of localization based on traveling wave fault location is established by using D-type doubleterminal traveling wave fault location algorithm. Traveling wave generated due to different defects in the high voltage networks with series-compensation are modeled a transmission line 735KV, 300km, 50Hz is simulated using SIM POWER SYSTEMS /MATLAB, we used The transient current and voltage signals are obtained from the model in algorithm who based on tow-end data The algorithm is implemented in MATLAB theses algorithms can locate the fault with high accuracy.
