Title
(EN) NACELLE YAW TOOL FOR ACTIVE YAW MITIGATION OF WIND INDUCED VIBRATIONS
(FR) OUTIL D'ORIENTATION DE NACELLE POUR ATTÉNUATION À MÉCANISME D'ORIENTATION ACTIF DES VIBRATIONS INDUITES PAR LE VENT
Abstract
(EN)
The invention relates to a wind turbine nacelle yaw tool, use thereof and a method of reducing wind induced vibrations of a wind turbine tower. The wind induced vibrations may be vortex induced vibrations and/or vibrations due to galloping. There is in one aspect of the invention disclosed a wind turbine nacelle yaw tool including; a controller for controlling yawing of the nacelle relative to a tower of the wind turbine, the controller being arranged with an output for a driving system including at least one yawing motor for yawing the nacelle relative to the tower, a power system for powering the nacelle yaw tool, and a vibration sensor connected to an input of the controller, and for sensing vibrations of the wind turbine tower. The controller is arranged to receive input from the vibration sensor, and based on said input to output a yaw command.

L'invention concerne un outil d'orientation de nacelle d'éolienne, son utilisation et un procédé de réduction des vibrations induites par le vent d'une tour d'éolienne. Les vibrations induites par le vent peuvent être des vibrations et/ou des vibrations induites par vortex dues au galop. Un aspect de l'invention concerne un outil d'orientation de nacelle d'éolienne comprenant : un dispositif de commande pour commander l'orientation de la nacelle par rapport à une tour de l'éolienne, le dispositif de commande étant agencé avec une sortie pour un système d'entraînement comprenant au moins un moteur d'orientation pour faire tourner la nacelle par rapport à la tour, un système d'alimentation pour alimenter l'outil d'orientation de nacelle, et un capteur de vibrations connecté à une entrée du dispositif de commande, et pour détecter des vibrations de la tour d'éolienne. Le dispositif de commande est conçu pour recevoir une entrée provenant du capteur de vibration, et sur la base de ladite entrée pour délivrer en sortie une commande d'orientation.
