RÉSUMÉ. Le système de conversion de l’énergie mécanique en énergie électrique comprend un moteur, une génératrice et une charge. Une interface mécanique placée entre le moteur et la génératrice adapte la vitesse de rotation des deux maillons, tandis qu’une interface électrique reliant la génératrice et la charge assure la stabilité de la fréquence et des niveaux des signaux électriques de la charge. Les contraintes électriques de la génératrice synchrone à rotor bobiné de la chaine et la vitesse du vent ABSTRACT. System of mechanical energy conversion into electric energy includes a motor, a generator and a load. A mechanical interface placed between the motor and the generator adapt the two links rotation speed, while an electric interface connecting generator and load ensures the frequency and the load electric signals levels stability.
