In this paper, a power production system containing a variable speed wind turbine equipped with a Doubly Fed InductionGenerator (DFIG) is presented, the DFIG stator is connected directly to the grid, and the rotor is connected by a three levelthree phase inverter with a Neutral Point Clamping structure (NPC). This last must be then dimensioned to forward only theavailable power of the rotor. In this work, a comparative study of two command strategies of the inverter is detailed, byseparate order control: Firstly Sinus Pulse Width Modulation (SPWM) and secondly Sinus Vectorial Pulse Width Modulation(SVPWM). All the simulation models are built in MA TLAB/Simulink software and the performance of the control system isevaluated through FFT analysis of results.
