摘要：

This paper describes an accurate fault location algorithms based on two end measurements of voltage and current phasors for EHV transmission lines. The algorithm is implemented for plain, shunt and series compensated, transposed and untransposed transmission lines. The algorithm is free of source impedance variations and includes the effect of shunt capacitance. The effect on the accuracy of the algorithm due to point on wave of fault initiation, fault location on the line, fault type, variations of the fault resistance and errors due to signal processing, is investigated. The algorithm is found to be very accurate for plain and shunt compensated lines but needs further improvements to cater for series compensated lines. Copyright (C) 1998 IFAC.
