Özet

Accurate estimation of fault location is essential for reliability of power system. For this purpose, fault location algorithms are studied and compared in this paper. These algorithms are based on the measurements taken from either sending end of a transmission line or both sending and receiving ends of the line. The types of fault location algorithms are discussed first. The effectiveness of the algorithms are tested on a faulty transmission line simulated in DigSILENT. Algorithms developed in MATLAB use the voltage and current values obtained from the simulated system. The impact of the fault distance, fault types and the fault resistance are examined in detecting the fault location. The study results reveal that the symmetrical fault location algorithm accurately estimates the fault location in all cases.
