Dynamic Simulation of a
Three-Phase Induction Motor Using Matlab Simulink
ABSTRACT:
The
theory of reference frames has been effectively used as an efficient approach
to analyze the performance of the induction electrical machines. This paper
presents a step by step Simulink implementation of an induction machine using
dq0 axis transformations of the stator and rotor variables in the arbitrary
reference frame. For this purpose, the relevant equations are stated at the
beginning, and then a generalized model of a three-phase induction motor is
developed and implemented in an easy to follow way. The obtained simulated
results provide clear evidence that the reference frame theory is indeed an
attractive algorithm to demonstrate the steady-state behavior of the induction
machines.

CONCLUSION:
In
this paper, an implementation and dynamic modeling of a three-phase induction
motor using Matlab/Simulink are presented in a step-by-step manner. The model
was tested by two different ratings of a small and large induction motors. The
two simulated machines have given a satisfactory response in terms of the
torque and speed characteristics. Also, the model was evaluated by Matlab
m-file coding program. Both methods have given the same results for the same
specifications of the three phase induction motors used in this simulation. This
concludes that the Matlab/Simulink is a reliable and sophisticated way to
analyze and predict the behavior of induction motors using the theory of
reference frames.
