Contrôle-commande d'un générateur asynchrone à double alimentation avec système de stockage pour la production éolienne

Abstract : This thesis deals with the design, analysis and simulation of a constant grid power wind energy conversion system based on electrical energy storage and indirectly controlled doubly fed induction generator (DFIG). This horizontal axis wind turbine system generates a constant active power through the grid under all wind conditions. The incorporation of a battery or other energy storage device in the DC link enables temporary electrical energy storage. The modelling of the mechanical part of the turbine is particularly detailed, a variable blade pitch wind turbine is used for maximal power extraction. Then, modelling, direct control and indirect control of the DFIG are presented. Independent control of active and reactive powers is achieved and the storage unit rating for this operation is particularly detailed. The Maximum Power Point Tracking (MPPT) control of this unit is also discussed. Simulation results validate the study for two experimental long duration wind speed profiles. This wind energy conversion system can offer some system service like power factor compensation or harmonic minimisation. So, the DFIG is used, with an additional control, to reduce harmonics currents present in the grid. This system facilitates the integration of the wind turbine in the distribution network because the manager of the grid can have a constant active power and some useful systems services.
