Abstract[English]
The invention provides a method for a wind turbine, having rotor assembly including a rotor hub and rotor blades, to be performed when the rotor assembly is in a partially installed state in which one or more of the rotor blades is finally installed in the rotor hub and one or more of the rotor blades is in a pre-installed state relative to the rotor hub. The method includes receiving sensor data indicative of vibrations of the rotor blade(s) finally installed in the rotor hub, and determining, based on the received sensor data, whether an amplitude of the vibrations of the rotor blade(s) finally installed in the rotor hub exceeds a defined threshold amplitude. If the vibrations amplitude exceeds the threshold amplitude, then the method includes outputting a signal for adjusting pitch of at least one of the finally installed rotor blades to reduce the vibrations amplitude.[French]
L'invention concerne un procédé pour une éolienne, ayant un ensemble rotor comprenant un moyeu de rotor et des pales de rotor, à effectuer lorsque l'ensemble rotor est dans un état partiellement installé dans lequel une ou plusieurs des pales de rotor sont finalement installées dans le moyeu de rotor et une ou plusieurs des pales de rotor sont dans un état pré-installé par rapport au moyeu de rotor. Le procédé consiste à recevoir des données de capteur indiquant des vibrations de la ou des pales de rotor finalement installées dans le moyeu de rotor, et à déterminer, sur la base des données de capteur reçues, si une amplitude des vibrations de la ou des pales de rotor finalement installées dans le moyeu de rotor dépasse une amplitude de seuil définie. Si l'amplitude de vibrations dépasse l'amplitude seuil, alors le procédé comprend la sortie d'un signal afin d'ajuster le pas d'au moins l'une des pales de rotor finalement installées pour réduire l'amplitude de vibrations.
