Abstract

Système à éolienne tournant à vitesse variable et permettant d'éviter les inconvénients et les lacunes des éoliennes classiques à vitesse variable et à vitesse fixe. Il s'agit d'un système à engrenages planétaires de transformation à vitesse variable, destiné à être utilisé en association avec les éoliennes à vitesse variable dans les systèmes de transformation de l'énergie éolienne dotés de trois configurations mécaniques: une mécatronique de commande d'actionnement commandée par un microprocesseur (300), un actionneur (200) comprenant trois engrenages de transfert à inversion (600), et une unité de transformation à vitesse variable (400) dudit système à engrenages planétaires. La force de rotation d'entrée à vitesse variable engendrée par la vitesse du rotor variant en fonction de la vitesse du vent est transformée en force de sortie déterminée à vitesse constante, par réglage de la vitesse de rotation et du sens de rotation de la couronne (440) du système de transformation. La commande du fonctionnement est obtenue à partir du système à microprocesseur et d'un capteur de contrôle de la vitesse de rotation de l'arbre d'entrée ou de sortie afin de pré-régler la force de sortie à vitesse constante. Par conséquent, ce système permet de produire un courant de secteur de grande qualité à l'aide d'une éolienne à vitesse variable et sans utiliser de système onduleur à électronique de puissance.
