The Dynamic Modelling and Electrical Profiles of Three Phase Induction Motor Using MATLAB Program

Abstract

This paper addresses the dynamic behaviour of 3-? induction machines based on a quality mathematical model and computer program simulation in a stationary reference frame to avoid the complexity involved in the course of solving time-varying differential equations obtained from the dynamic model. Laplace transform of the dynamic equations was carried out to derive analytical solutions the current variables.  4^th 0rder Runge-Kutta method is adopted to give numerical solution of the dynamic model. The basic electrical characteristics of the 3-? induction machine are considered in the two-phase approximate equivalent model. The graphical curves were obtained from MATLAB program code developed.
