This paper presents a novel accurate fault location algorithm for UHV transmission line.Based on phase-modal transformation technique and distributed parameter transmission line model,the algorithm utilizes quasi-Newton method to resolve non-linear equation sets allowing for data sampling asynchronization at both terminal.The simulation results of EMTP show that it has high accuracy.
