Abstract

This paper presents two methods for on-line computation of dynamic fault location in HV transmission lines using three means; resistance, reactance and impedance. These methods can be used for dynamic distance protection of the transmission line. The Gilchrist method and McInnes method are presented. The proposed methods use digital set of short circuit current and voltage measurements for estimating fault location. A practical case study is presented in this work to evaluate the proposed methods. A study is done to evaluate the best mean to locate the fault. A comparison of these two methods is presented. MATLAB-Simulink software was used to do all the tests. Results are reported and conclusions are drawn.

Highlights

  • The problem of fault location on transmission lines has been the focus of interest of many researchers in power systems for years

  • The earlier developed one is one-terminal data method, and the other is the currently more prevalent one so-called two-terminal method. These methods use voltage and current phasors to determine the impedance to the fault location, and both suers from errors mentioned in many papers [3]-[6]

Summary

Introduction

The problem of fault location on transmission lines has been the focus of interest of many researchers in power systems for years. The purpose of a protective relays is to clear the fault as quickly as possible, minimize the damage caused due to fault and restore the line quickly. Another important job is to locate this fault point accurately. The earlier developed one is one-terminal data method, and the other is the currently more prevalent one so-called two-terminal method. These methods use voltage and current phasors to determine the impedance to the fault location, and both suers from errors mentioned in many papers [3]-[6]. We present two methods for dynamic locating fault in the transmission line using sampling data of current and voltage sigc 2017 Journal of Advanced Engineering and Computation (JAEC)
