Abstract

Thevenin’s method of approach for analyzing electrical power circuit parameters is presented in this paper. Two different MATLAB programs were written to determine the performance of the Nigerian National Electric Power Authority (NEPA) 330kv transmission grid system. One of the MATLAB programs was for load flow study  know the pre-fault condition which is based on gauss-seidel method; while the other is for short circuit studies which indeed made use of thevenin’s method of approach to solve problems on a  closed circuit. Various kinds of line-line faults and line-ground faults were simulated and was found that the energy released from a 3-phase fault is most enormous.
