Title
(EN) ACTIVE YAW MITIGATION OF WIND INDUCED VIBRATIONS
(FR) ATTÉNUATION À MÉCANISME D'ORIENTATION ACTIF DES VIBRATIONS INDUITES PAR LE VENT
Abstract
(EN)
The invention relates to a method and a wind turbine system reducing, preventing or mitigating vibrations due to wind induced vibrations. The wind turbine system includes a wind turbine tower 102, a sensor arrangement 304 for sensing vibrations of the wind turbine tower, a nacelle 104 mounted to the wind turbine tower via a yaw bearing 310 and a control system 306 for controlling yawing of the nacelle relative to the wind turbine tower. The system is adapted for sensing 402 a vibration of the wind turbine tower using the sensor arrangement, providing 404 an input for the control system in response to the vibration of the wind turbine tower as sensed by the sensor arrangement, and providing 406 an output by the control system based on the input, and yawing 408 the wind turbine nacelle based on the output from the control system, and hereby reducing wind induced vibrations of the tower and nacelle, particularly vortex induced vibrations and/or vibrations due to galloping.

L'invention concerne un procédé et un système d'éolienne de réduction, de prévention ou d’atténuation des vibrations induites par le vent. Le système d'éolienne comprend une tour d'éolienne (102), un agencement de capteur (304) pour détecter des vibrations de la tour d'éolienne, une nacelle (104) montée sur la tour d'éolienne par l'intermédiaire d'une couronne d'orientation (310) et un système de contrôle (306) pour contrôler le lacet de la nacelle par rapport à la tour d'éolienne. Le système est conçu pour : (402) détecter une vibration de la tour d'éolienne à l'aide de l'agencement de capteur, (404) fournir une entrée pour le système de contrôle en réponse à la vibration de la tour d'éolienne telle que détectée par l'agencement de capteur, et (406) fournir une sortie au moyen du système de contrôle sur la base de l'entrée, et (408) faire tourner la nacelle d'éolienne sur la base de la sortie provenant du système de contrôle, ce qui permet de réduire les vibrations induites par le vent de la tour et de la nacelle, en particulier des vibrations induites par vortex et/ou des vibrations dues au galop.
