摘要：In this paper, a power production system containing a variable speed wind turbine equipped with a Doubly Fed Induction Generator (DFIG) is presented, the DFIG stator is connected directly to the grid, and the rotor is connected by a three level three phase inverter with a Neutral Point Clamping structure (NPC). This last must be then dimensioned to forward only the available power of the rotor. In this work, a comparative study of two command strategies of the inverter is detailed, by separate 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 is evaluated through FFT analysis of results.
