Location of Faults on Nigeria 330kv Power Transmission Lines Using Traveling Wave
Subject area: Science,Engineering and Technology · Area of research: Power System
Abstract
This paper studies the decrease in fault impedance of a transmission line when simulated for three-phase fault with an increase by 10Km in line distance from 10Km to 100Km using MATLAB/Simulink mathematical model of travelling wave. Fault location was performed on a 96Km330KV Onitsha ? Enugu Power system Transmission Line. The proposed method uses the measured fault voltage and current signals of the three phase lines as input to the fault detector and locator. The result show that, when the fault distance MATLAB/Simulink Travelling Wave fault location model is simulated for three-phase fault with geometrical increase in transmission line distance, the impedance and velocity of the travelling wave of the line decreases with sharp decrease and increase in voltage and current magnitudes respectively.
