Abstract
DISPOSITIF POUR LA COMMANDE DES PALES D'UN AÉROGÉNÉRATEUR Chaque pale (7) est reliée à des moyens de rotation autour de son axe longitudinal, servant à modifier l'angle d'attaque des pales (7) par rapport au vent et à sélectionner la puissance requise tout en maintenant une vitesse constante du rotor, ou à provoquer l'arrêt des pales (7) au moment où est dépassée une vitesse de rotation préalablement établie ; le dispositif est caractérisé en ce que les moyens de rotation se composent d'un moteur électrique (11) à vitesse variable et fonctionnant par commande électronique, d'une motopompe hydraulique (10) montée sur un circuit hydraulique (1) conventionnel et de moyens de commande (12) pour engager la rotation des pales (7) à l'aide du moteur électrique (11) et à travers la motopompe hydraulique (10) lorsqu'il y a du courant électrique, et pour engager la rotation des pales (7) uniquement à l'aide du module de la commande de sécurité et détresse (4) et de l'accumulateur hydraulique de sécurité et détresse (5) lorsque l'alimentation électrique fait défaut.
