Dynamic Performance Analysis of Three Phase Induction Motor Using Matlab/Simulink Technique
Abstract
In this paper a good mathematical model for three phase induction motor using their electrical and mechanical equations which describe its operation and performance. The modern computational technique (Matlab/Simulink) has been used to study transient conditions of the motor. The behavior of the motor observed according to their speed, torque, stator current and rotor current by subjecting the motor to different conditions like, starting, sudden load, one phase disconnected, sudden increasing or decreasing the motor voltage and lightning effect. The model is used to investigate the effects of variation in the machine size on the dynamic performance, to select the appropriate motor for specific application. The simulation results show the activity of the modern technique in predicting the behavior of an induction motor under different operating conditions.
