摘要
Abstract
This paper introduces a new fault location algorithm for Transmission Lines, which derives the fault location equation from the relationship between the voltages and currents of positive sequence and negative sequence networks when fault happened. This method not requires line parameters, only by means of the GPS synchronization to acquire the voltages and currents data at both ends of the transmission line, and does some related processing about these data.Then,with the help of the location equation, we can get the accurate fault distance very easily. Compared with traditional methods, this algorithm not only uninfluenced by the disturbances of the changes of transition lines, the fault location and its environment and the fault resistances, but also simple, flexible and more useful. A lot of simulations by the Matlab software have been done, and the results proved the correctness of the algorithm.关键词
