Abstract

This paper proposes a fault location algorithm for two-parallel transmission line in the case of single line-to-ground fault Proposed algorithm is using voltage and current measured in the sending-end. The fault distance is simply determined by solving a second order polynomial equation due to the direct circuit analysis. The simulations by PSCAD/EMTDC have demonstrated the accuracy and effectiveness of the proposed algorithm.
