Abstract


The paper proposes a direct power control (DPC) 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 three-level NPC inverter. We propose to control the DFIG with a technique based on the DPC control performances. A combination of a three-level neural space vector pulse width modulation (3L-NSVPWM) strategy and reactive and active power controllers is made to replace hysteresis comparators used in the traditional DPC drive resulting in a fixed switching frequency of the power converter. The performances obtained by using this control technique are shown under Matlab/Simulink software

Keywords
