Title
(EN) FLOATING WIND TURBINE PLATFORM CONTROLLED TO OPTIMIZE POWER PRODUCTION AND REDUCE LOADING
(FR) PLATEFORME DE TURBINE ÉOLIENNE FLOTTANTE COMMANDÉE POUR OPTIMISER LA PRODUCTION D'ÉNERGIE ET RÉDUIRE LE CHARGEMENT
Abstract
(EN)
A method for controlling an inclination of a floating wind turbine platform to optimize power production, or to reduce loads on the turbine, tower, and platform, or both, includes receiving data associated with the inclination of the floating wind turbine platform and wind speed and direction data. An angle of difference between the turbine blade plane and the wind direction is determined, where the angle of difference has a vertical component. A platform ballast system is then caused to distribute ballast to reduce the vertical component to a target angle chosen to optimize power production, or reduce turbine, tower, and platform loads, or both.
(FR)
L'invention concerne un procédé de commande d'une inclinaison d'une plateforme de turbine éolienne flottante pour optimiser la production d'énergie ou pour réduire les charges sur la turbine, la tour et la plateforme ou les deux, consistant à recevoir des données associées à l'inclinaison de la plateforme de turbine éolienne flottante et des données de vitesse et de direction du vent. Un angle de différence entre le plan de pale de turbine et la direction du vent est déterminé, l'angle de différence ayant un composant vertical. Un système de ballast de plateforme est ensuite amené à distribuer un ballast pour réduire le composant vertical jusqu'à un angle cible choisi pour optimiser la production d'énergie ou réduire les charges de turbine, de tour et de plateforme ou les deux.
