Simulation of Transmission Line using MATLAB

Abstract

The demand of electricity increases day by day these results to transmit more power by increasing the transmission line capacity from one place to the other place. The main goal is to develop a MATLAB based Simulation model for analyzing 3- phase symmetrical and unsymmetrical faults on power transmission lines. Generally, these faults occur in the long transmission line system such as single line to ground fault (L-G), double line to ground (2L-G), triple line to ground fault (3LG) and Line to line fault (L-L). Fault analysis for different kinds of faults has been done and it impacts are appeared in simulation results such as current and voltage. This results into the MATLAB software in which transmission line model is simulated. MATLAB can manipulate and invert large matrices and can be used in many several applications. MATLAB is more convenient with a recent addition called Simulink, a program which is normally used in the analysis of modern control systems. Simulink, now incorporated into MATLAB, can also be used to design distributed transmission lines. In addition to demonstrating its wider applicability, many examples are included that are normally described in books or papers directed to the study of faults along transmission lines. As the importance of energy efficiency grows for companies and government regulators, so does the need for theoretical analysis.
