A Modelling of 440 KV EHV Transmission Line Faults identified and Analysis by Using MATLAB Simulation

Satish Karekar, Tripti Barik

As we know electricity or electrical power are increases day by day and transmits more electrical power by increasing the transmission line capacity from one sub-station to another sub-station. During some faults are occurred 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). These types faults are affecting the electrical power system equipment’s/component which are connect in EHV Transmission line. Mainly the major faults in long transmission lines is (L-G) single line to ground fault which are harmful to the electrical equipment. A proposed model in 300km/440kv EHV transmission line are simulated in MATLAB software to analysis and identified the faults.Fault block was taken from the sim-power system block library. The whole modelling and simulation of different operating and different conditions of fault on EHV transmission line, their faults are L-G fault, 2L-G fault, 3L-G fault and three line short circuit of the proposed work is presented in this paper.
