Abstract

Abstract: When the high-voltage transmission lines break down,a new fault location method based on strong tracking filter theory is presented in order to locate the fault point quickly and accurately.In this method,the effect of the sampling frequency to the fault location error is studied with the strong tracking filter algorithm.The state equation is simple and accurate.The strong tracking filter algorithm is applied in the PSCAD/EMTDC software,and the results show that the calculation is simple and accuracy,and it does not need to solve complex mathematical equations,and the noise can be eliminated better and faster using strong tracking filter algorithm.This paper focuses on the research that the sampling frequency affects the fault location error,providing the device of electric power system with the strong tracking filter algorithm.

Key words: transmission line, sampling frequency, fault location, strong tracking filter
