The objective of this article is the study of the Doubly Fed Induction Generator (DFIG) used in the production of wind energy as well as the optimization of the quality of the energy produced by wind turbine by manipulating the heights of the active and reactive power as needed. We use the approach of the control of the converters AC-DC-AC. The optimization of the energy produced by a machine with double feeding will be performed by a group of regulators PI and mathematical equations according to Park’s transformation. The control used will be the vectorial control in power of the (DFIG). In our study, the frequency is constant and the vectorial control in power consists in making DFIG undergo a power instruction with the best electric dynamics and taking into consideration the limit of the frequency conversion of switches of power converters. The converter of the machine must ensure the regulation of the exit tension of the rectifier. However, the converter on the side of the electric grid makes it possible to ensure the regulation of tension of continuous bus while absorbing the current which must be as sinusoidal as possible, with the possibility of setting the power factor. The results are made in Matlab-Simulink.
