   A VECTOR ORIENTED CONTROL STRATEGY FOR A 4-QUADRANT LINE SIDE CONVERTER
By W. A. .G de Jager; G. H. Tubbing [View]
[Download]

Abstract: This paper gives a description of the modelling and control of a 4 quadrant lineside converter. The converter is part of a traction drive supplied by the 25 kV, 50 Hz overhead line. A model of the bridge in a moving reference frame of coordinates is used to develop a new type of control. The control system has separate controllers for the active and reactive current, permitting the free choice of the power factor. As the control system has no instantaneous current control, no extra fast hardware is required. A comparison is made between simulation results and measurements on a full scale test bench.

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.
