To aim at the distributionparameter characteristics of UHV transmission line, this paper presents a fastextraction method FE to extract the accurate fundamentals of current andvoltage from the UHV transmission line transient process, and locates the faultby utilizing two-end unsynchronized algorithm. The simulation result shows thatthis method has good performance of accuracy and stability, and has betterlocation precision by comparing with results of one cycle Fourier algorithm. Thereforethe method can efficiently improve the precision of fault location during thetransient process, and makes the error of location results less than 0.5%.
