Modeling and analysis of multi machine power system

Abstract

Multi machine power system is consists of different types of generators, all sorts of power load, different voltage levels of power network consisting of very large complex dynamic system. The transient process includes not only electromagnetic transient process, and electromechanical transient process. Thus, the mathematical model of the power system is a strong nonlinear high dimensional state equations. Using simple power system model in dynamic stability simulation. Through simulation analysis shows that, this method can be a simple power system transient analysis, to improve the transient stability of power system has important significance.

Power system simulation has become one of the most commonly used methods in the design, operation and control of power system.This paper mainly through the MATLAB software for power system simulation environment, first of all to make the simulation of a single machine power system, and then make the simulation of multi machine power system. And the cause of the fault analysis, finally draws the conclusion.

Key words: multi machine power system MATLAB simulation modeling
