Modelling of induction machine time and space harmonic effects in the SIMULINK environment

High fidelity ac machinery models including harmonic effects are becoming increasingly desirable for use in improved fidelity machine and drive behavior analysis. This paper describes a method enabling the development of a dynamic induction machine model in SIMULINK which has a capability of representing time and space harmonic effects. The manuscript first presents the details of the model development and implementation. The proposed model performance is then validated through comparison with experimental current and torque signals data obtained from two separate induction machine laboratory test rigs. The results show a good agreement between measured and predicted data in the frequency domain and validate the competency of the presented model in representing harmonic effects.
