Abstract

Phasor Measurement Units (PMUs) have gained a great popularity in the field of control and wide area protection during the last decade. One of the major protection applications based on PMUs technology is to determine the fault location in a transmission line. Therefore, several researches have been developed in the field of fault location. Some of the researches are based on one-end measurements. But, a greater accuracy has been achieved on the basis of two-end measurements. Many researchers suggested only voltage measurements to avoid the current transformers (CT) errors. While, others suggested methods depend on both voltages and current measurements with a higher accuracy CTs. A few researches have been developed in fault location of series compensated line. This paper introduces a generalized model of fault location algorithm for both uncompensated and series compensated transmission line. The proposed algorithm is based on the distributed parameters of the transmission line in the determination of fault location. Moreover, the proposed algorithm utilizes the synchronized measurements of voltages and currents at both ends of the line. The proposed algorithm is general for any allocation of series compensation elements. The proposed algorithm is tested through the PSCAD offline simulation program and the mathematical analysis with the aid MATLAB.
