Abstract

Centrale éolienne à pales oscillantes comportant un système de réglage de la vitesse de rotation et d'emmagasinage d'énergie. Cette centrale comporte une structure portant la roue de l'arbre vertical (1), et cette roue est constituée de matériaux de construction légers et dotée d'anneaux externes (7), de rayons (8) et de systèmes d'ancrage vertical et horizontal pourvus de barrettes minces ou de câbles souples (5) assurant une rotation silencieuse et une réduction des contraintes dynamiques. Le processus de réglage de la rotation s'effectue à l'aide de deux paires de dispositifs particuliers d'ouverture et de fermeture (15, 16) intervenant sur la course de chaque pale (3). Ces dispositifs (15, 16) règlent la vitesse de rotation et protègent la centrale contre les vents forts (arrêt) ou mettent les pales (3) hors service, en cas de défaillance. Par ailleurs, lesdits dispositifs (15, 16) amortissent les chocs en limitant la course de la pale au moyen d'un champ magnétique ou électromagnétique ou de matériaux élastiques, de sorte que les pales (3) produisent des forces utiles lors de leur demi-rotation de retour (contre le vent). L'emmagasinage du vent permet une exploitation optimisée de l'énergie éolienne, de 4 m/s à 50 m/s, par transformation de cette énergie en électricité, sans limitations de tension et de fréquence, cette électricité pouvant être transformée à son tour en énergie chimique, thermique et potentielle, et emmagasinée selon le dessin représenté par la Fig. 11.
