摘要/Abstract

摘要： 当输电线路发生故障时,要快速、准确、可靠地对故障进行定位,从而提出了一种基于强跟踪滤波器理论的故障测距方法.在搭建的模型中,基于强跟踪滤波器算法原理,不同的采样频率下,故障测距的误差是不同的,结果与解微分方程法测得结果接近,说明建立的测距模型是准确的.在PSCAD/EMTDC软件下,对强跟踪滤波算法进行仿真分析,仿真结果表明,该算法是一种简单的递推算法,原理简单,不需要求解复杂的数学方程,能更好、更快的消除噪声,使信号收敛快,实施性好,鲁棒性好.本文主要研究不同采样频率仿真下误差的不同,为基于强跟踪滤波器算法的电力系统故障测距装置提供了理论依据.

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.
