Abstract:
In the present work the performance of induction motor in traction system, which is fed by voltage source inverter, is investigated. The inverter is operated in space vector mode to make input and output current sinusoidal. The machine is modeled using d-q axis transformation. The transient and steady state performance of the induction motor is investigated for traction load. For obtaining speed control in whole speed range, a control scheme for Direct Torque Control and flux control (DTFC) of induction motor based on stator flux field-orientation method, is used.
