摘要：

This paper presents a new scheme of fault location on power system comparing actual measurements of voltage sag to fault current calculation results. Using a two-circuit transmission line fault analysis tool developed by CRIEPI*(1) for calculating voltage sag value, this scheme can locate a faulted point not depending on causes of the faults. By estimating fault point impedance, highly accurate fault location is expected. From a viewpoint of practical use, the presented scheme is applied to a real power system model of a Japanese electric power company using practical voltage sag measurement values at substations on subtransmission system. Results of this evaluation show that this scheme has a possibility of having practical accuracy of the fault location.
