EFFICIENCY IMPROVEMENT OF THREE PHASE SQUIRREL CAGE INDUCTION MOTOR BY CONTROLLING THE APPLIED VOLTAGE TO THE STATOR


Abstract: Optimizing the efficiency of three phase squirrel cage induction motors (SCIMs) plays a big role in saving electric energy consumption. The aim of this thesis project is to operate a three phase SCIM with maximum allowable efficiency at light loads by controlling the applied voltage to the motor using MATLAB/SIMULINK. Mathematical analysis and parameter identification of three phase SCIM are explained. Because of its simplicity of use, MATLAB/SIMULINK is employed to determine motor parameters and to simulate a three phase SCIM under different loads. The effect of voltage variation on motor characteristics such as motor current, torque, speed, power factor, and efficiency in stable and unstable regions of operation is explained. A comparison between conventional operation and maximum efficiency operation is performed.
