Energy conservation study on induction motors using MATLAB/Simulink for enhancing electric machinery courses

This paper describes MATLAB/Simulink implementation of optimal excitation control on a three-phase induction motor (IM) for energy conservation at light loads. This simulation model is developed to support and enhance Loss Minimization Control (LMC) on electric machinery education at the undergraduate and postgraduate level in electrical engineering. This study provides the saving of real, reactive and total power of the motor (1 hp) operating with mine-hoist load diagram.
