Abstract:

Induction motors are the most widely used electrical motors due to their reliability, low cost and robustness. However, induction motors do not inherently have the capability of variable speed operation. Due to this reason, earlier dc motors were applied in most of the electrical drives. But the recent developments in speed control methods of the induction motor have led to their large scale use in almost all electrical drives. Out of the several methods of speed control of an induction such as pole changing, frequency variation, variable rotor resistance, variable stator voltage, constant V/f control, slip recovery method etc are conventional control methods. With advances in solid-state power electronic devices and microprocessors, various pulse-width-modulation (PWM) techniques have been developed for industrial applications to control the speed of the induction motor. This thesis discuss about the speed control of induction motor by using Space Vector Pulse Width Modulation (SVPWM) technique. In this thesis we vary the speed of the induction motor in two cases one is accelerating mode and another is decelerating mode. The simulation results show that the SVPWM technique has lower total harmonic distortion than the SPWM technique. The SVPWM technique in the under-modulation region can increase the fundamental output voltage by 15.5% over the SPWM technique.
