Steady State And Transient Performance Analysis Of Three Phase Induction Machine Using Matlab Simulations

Full text: PDF


DC drives have hitherto been widely used in various Industrial applications but recent device technology and high speed microprocessors have tilted the balance and the induction machine is becoming the workhorse of the electrical power industry. Computer based modeling and simulation of induction machine has certainly opened new horizons for the performance analysis. A good mathematical model can help in predicting the behavior of an induction machine under different operating conditions and in selecting the appropriate machine for a specific application.

This paper presents a quality mathematical model of induction machine based on the steady state and dynamic equations and D-Q transformation technique. This model can be used for steady state as well as transient analysis of squirrel cage or wound rotor structure. The model is used to investigate the effects of variations in the machine size and parameter values on the dynamic performance of induction machine. Different operating conditions are simulated using MatLab code. Also, the behavior of the induction machine is observed with and without supply harmonics.
