Transmission line Three-Phase Fault Analysis Using Matlab Simulink

Abstract

Abstract: The Electric Power System has many different sections, transmission system is one of. Where power is transmitted from generating stations and substations via transmission lines into consumers. In the Power System causes of faults are many, they include lighting, wind damage, trees falling across transmission lines, vehicles or aircraft colliding with the transmission towers or poles, birds shorting lines. The fault occurring in power system can be broadly classified into symmetrical and unsymmetrical fault. Generally these faults are occurred in the long transmission line system such as single line - ground fault (L-G), double line - ground (2L-G), triple line - ground fault (3LG) and Line - line fault (L-L). The transmission line fault analysis helps to select and develop a better for protection purpose. This paper ways to deal with the MATLAB programming in which transmission line model is composed and different issues has been reenacted utilizing tool compartment. Fault Analysis for different sorts of faults has been done and it impacts are appeared in simulation output, for example, voltage, current, control alongside the positive, negative and zero grouping segments of voltage and current output as far as waveforms.
