The present invention concerns a wind power installation comprising a pylon and a rotor arranged on the pylon and having at least one individually adjustable rotor blade, comprising a device for detecting the wind direction and a device for detecting the azimuthal position. The object of the present invention is to develop a wind power installation of the kind set forth in the opening part of this specification in such a way that the service life of the azimuthal drives is prolonged and/or it is possible to use smaller azimuthal drives which can thus be better handled. A wind power installation comprising a pylon and a rotor arranged on the pylon and having at least one individually adjustable rotor blade, comprising a device for detecting the wind direction and a device for detecting the azimuthal position, characterised by a control of rotor blade adjustment in dependence on a deviation between the ascertained wind direction and the detected azimuthal position.

L'invention concerne une installation d'énergie éolienne comportant une tour et un rotor monté sur la tour avec au moins une pale de rotor à ajustement individuel, comprenant un dispositif pour détecter la direction du vent et un dispositif pour détecter une position azimutale. L'invention vise à perfectionner une installation d'énergie éolienne du type décrit, de sorte à prolonger la durée de vie des commandes azimut et/ou à permettre l'utilisation de commandes azimut plus petites et plus aisées à manipuler avec. L'invention concerne une installation à énergie éolienne comportant une tour et un rotor monté sur la tour, qui présente au moins une pale de rotor à ajustement individuel, un dispositif pour détecter la direction du vent et un dispositif pour détecter la position azimutale, qui se caractérise par une commande du déplacement de la pale de rotor en fonction d'un écart entre la direction du vent déterminée et la position azimutale détectée.
