SIMULATION MODEL FOR INDUCTION MOTOR DRIVE

Abstract-Induction Motor Drives (IMD) have been widely used from last many years in various industrial as well as transportation systems i.e. hybrid /electric vehicles, and electric propulsion ships, where variable speed and constant torque with high performance requirements are demanding increasingly. This paper presents an introduction of indirect and direct ac/ac power conversion schemes, various topologies. It presents Comprehensive description of the model of induction motor drive in abc reference frame and then the motor model is derived in arbitrary reference frame using Park’s transformation. The d-q model equations are presented and developed the model in MATLAB/ Simulink. Simulation results of induction motor drive is obtained when three phase balanced supply is applied to three phase induction motor and motor drive is simulated at no load as well as full load conditions. The steady state characteristics of drive under rated voltage and frequency are presented in terms of torque, stator current, input power, developed power and efficiency with respect to speed of the drive. The results demonstrate the versatility of the presented induction motor model.
