Abstract
(DE)
Nach einer Ausführung eines Verfahrens zum Betreiben einer Windenergieanlage, die einen um eine Rotorachse drehbaren Rotor mit wenigstens zwei individuell um ihre Blattachse verstellbaren Rotorblättern und einen Nachführantrieb zum Windnachführen des Rotors um eine Gierachse (G) aufweist, werden in einem Nachführbetriebsmodus Blattwinkel der Rotorblätter um ihre Blattachse zur Unterstützung einer Windnachführbewegung durch den Nachführantrieb verstellt.
(EN)
Disclosed is a method for operating a wind turbine comprising a rotor that is rotatable about a rotor axis and includes at least two rotor blades which can be individually moved about the blade axis thereof, and comprising a tracking drive for moving the rotor about a yaw axis (G) in order for the rotor to track the wind. According to one embodiment of said method, in a tracking operating mode, blade angles of the rotor blades are adjusted about the blade axis by the tracking drive in order to assist a wind tracking movement.
(FR)
L'invention concerne un procédé permettant de faire fonctionner une éolienne qui comporte un rotor, pouvant tourner autour d'un axe de rotor, pourvu d'au moins deux pales de rotor pouvant être ajustées individuellement autour de leur axe de pale et un entraînement de poursuite servant à la poursuite de vent du rotor autour d'un axe de lacet (G). Après l'exécution du procédé, des angles de pale des pales de rotor sont ajustés dans un mode de fonctionnement de suivi autour de leur axe pour soutenir un mouvement de poursuite de vent par l'entraînement de poursuite.
