摘要
Abstract
For transmission lines, the paper analyzes the wave propagation process and the wave's refraction and reflection phenomena after the failure. On this basis, the paper proposes fault location method combining two traveling waves' theories. First, single-ended location principle is used to give preliminary fault location. And then the accurate results are given by single-ended principles combining with initial wave arrival time difference at both ends. The advantage of this method is that the results are obtained by single-ended location principle, eliminating the line length's error and the influence on location accuracy from circuit accurate time synchronization on both sides in double-ended principle location method so as to improve the accuracy and reliability of location. ATP simulations show that the combined traveling wave fault location scheme of transmission lines is feasible and fault location accuracy is improved obviously.关键词
