A Methodology to Develop A Simulink Model of Three Phase Induction Motor

Three phase induction motor is one of the most widely used motors as industrial, commercial and residential load. This motor has the simplest construction, reliable in operation, low initial cost, easy operation, simple maintenance, high efficiency and simple speed control. The popularity of this motor has resulted into lot of research including the transient behaviour of the motor. In this paper, transient performance of three phase squirrel cage induction motor is analyzed with dq0 axis based modeling in synchronously rotating reference frame. The parameters are being calculated by using the standard datasheet given by the manufacturer of the motors. The parameters of the motor are calculated first by using the MATLAB program then proposed system is developed and simulated by using MATLAB/SIMULINK. This paper gives the step by step procedure for developing the simulation model of induction motor in MATLAB Simulink using library Sim Power System.
