Optimizing solution of fault location

Abstract

This paper describes an assembled transmission line fault location algorithm based on one-terminal electrical quantities. It uses a fault location algorithm based on measurement impedance to calculate a fault section of a transmission line, then it uses a wavelet transform fault location algorithm based on current traveling wave to pinpoint the fault position. This algorithm deals with the conflict between accuracy and robustness of fault location algorithm successfully. The computer simulation demonstrates that the assembled fault location algorithm holds high robustness and high accuracy.
