Effect of variation in rotor resistance on the dynamic performance of induction motor

The paper presents a dynamic d-q model of the three-phase induction motor in the stationary reference frame using MATLAB Simulink environment. An intuitive and easy to use model is presented that clearly elaborates the steps regarding revolving reference frames. It gives a complete access to the monitoring of parameters of induction motor for verification and control purposes. The second part of the paper comprises of the effect of variation in rotor resistance on the dynamic performance of induction motor using the same model. Extensive nonlinear simulation results are incorporated that clearly elaborates the change in the dynamic performance of induction motor by changing the rotor resistance which becomes dominant due to temperature rise in motor.
