| Abstract |
The authors make use of a field-oriented control for high-power induction motor drives with KALMAN filter flux observation [1]. Such a control-structure, associated with a two-level GTO inverter, allows to supply asynchronous drives up to 900 kVA. In order to extend the power-range for the use of this control, the authors have utilized a three-level GTO inverter. The Space-Vector Modulation is chosen to obtain a better quality of the electromagnetic torque and the stator current of the induction motor. Precise simulations show the improvement obtained in comparison to a three-level GTO inverter with sinusoïdal Pulse-Width Modulation. The performances of the speed-drive have been tested at transient as well as steady-state operating. The behaviour of the complete speed-drive system has been studied carefully in all fourth quadrants of the torque-speed plan. |
