A direct power control of the doubly-fed induction generator based on the SVM Strategy
Résumé
This paper proposes a direct power control scheme for the doubly-fed induction generator (DFIG) for variable speed wind-power generation. The machine is connected as a generator. Its rotor is fed by a two-level inverter. We propose to control the DFIG with a technique based on the direct power control (DPC) performances. A combination of a space-vector modulation (SVM) technique and active and reactive power controllers is made to replace hysteresis controllers used in the classic DPC drive resulting in a fixed switching frequency of the power converter. The performances obtained by using this control strategy are shown under MATLAB Simulink.
