Abstract

This paper presents a new FAULT LOCATION method based on synchronized phasor measurement for two–terminal transmission lines. Due to some common problems of current transformers (CT) in power system protection such as low accuracy, this method wipes off the CT requirement. In other word, the method is only based on voltage measurement. Samples of voltage at both ends of line are taken synchronously and used to calculate the location of fault. The algorithm uses thevenin equivalent model of faulted system and SYMMETRICAL COMPONENTS theory for estimation of fault distance with reasonable error (0.7%). The proposed method is also independent of fault type, fault resistance, fault inception angle and line angle. In addition to these advantages, the proposed technique is improved by using MODIFIED algorithm in order to reduce the estimation error to less than one meter. Simulations with EMTP/ATP were performed to verify the accuracy of the proposed method.
