Performance of induction motor supplied with asymmetrical and nonsinusoidal supply voltages is studied in this thesis.
Theory of induction motor is first presented for sinusoidal symmetrical supply voltages. Equations for the torque, losses, currents and efficiency are derived. Appropriate changes are made to apply this theory to induction motors operating at nonsinusoidal and asymmetrical supply voltages. Single phase equivalent circuit of the induction motor is presented for both asymmetrical and nonsinusoidal supply voltages. The equations governing operating characteristics are presented. Machine torque, losses, current and efficiency for asymmetrical and nonsinusoidal supply voltages are compared with the same for sinusoidal symmetrical supply voltages. Computer simulation in MATLAB is used to study the impacts of asymmetrical and nonsinusoidal supply voltages on induction machines. Machine torque, losses, current and efficiency are calculated for various levels of voltage asymmetry and distortion. Results of computer simulation are presented.
