Abstract: An improved symmetrical component-based method is proposed in the paper. The proposed method uses phasor estimates of voltage and current samples obtained from both ends of a transmission line. The mathematical basis of the new approach is described. It is shown that the new method completely obviates complex arithmetic operations and has considerable computational advantages over the previously proposed methods. Furthermore, performance assessment studies on this new method using the alternative transient program (ATP) are presented and discussed. It is illustrated that the proposed method can determine the fault location very accurately and is likely to be used for digital distance protection and fault location. © IEE, 1998.
