Abstract

Three phase induction motors are widely used in Industrial drives because of their ruggedness, reliability and simplicity in construction. Accurate control of Induction Machine was always a matter of concern starting from the modulation technique used, to the closed loop control strategy. In this work a complete Induction Motor drive is designed for pumping application with modulation strategy as Sinusoidal pulse width modulation (SPWM) and control scheme as IFOC. The Induction Motor is fed by a cascaded H-Bridge 5 Level MLI and is controlled by Indirect Field Oriented Control (IFOC) technique. In this paper, Multi Carrier PWM technique Alternate Phase Opposition Disposition (APOD) is used to control switching of multilevel inverters. Mathematical model of Pump Load is designed and the performance of the Induction Motor Drive with Pump Load is analyzed using simulation. The affinity law of centrifugal pump is validated using the simulation results obtained.
