Indirect Vector Control of a DFIG Supplied by a Two-level FSVM Inverter for Wind Turbine System

Doubly fed induction generator (DFIG) is one of the most popular generators used nowadays in wind turbine systems (WTSs). This machine has some interesting advantages especially in variables speed applications. In the DFIG-based WTS, the rotor side of the machine is normally fed by a two-level power inverter controlled by the usual pulse width modulation (PWM) technique. This last has a principal disadvantages which is the high level of harmonic distortion. In this paper, we propose a novel technique based on space vector modulation (SVM) and fuzzy logic in order to performs the power provided by the DFIG to the grid. Simulation results show the efficiency of the proposed technique especially on the quality of the provided power comparatively to the usual PWM
