Abstract[English]
The invention relates to activation of a pitch controller for controlling pitch of rotor blades of a wind turbine. The invention includes receiving a sensor signal, from at least one sensor of the wind turbine, indicative of oscillatory motion of a component of the wind turbine. The invention includes determining, based on the received sensor signal, a magnitude of the oscillatory motion of the component, and determining, based on the determined magnitude, a rate of change of the magnitude of oscillatory motion. The invention includes controlling activation of the pitch controller based on the determined rate of change of the magnitude of oscillatory motion.[French]
L'invention concerne l'activation d'un dispositif de commande de pas pour commander le pas de pales de rotor d'une éolienne. L'invention consiste à recevoir un signal de capteur, en provenance d'au moins un capteur de l'éolienne, indicatif d'un mouvement oscillatoire d'un composant de l'éolienne. L'invention consiste en outre à déterminer, sur la base du signal de capteur reçu, une amplitude du mouvement oscillatoire du composant, et à déterminer, sur la base de l'amplitude déterminée, un taux de changement de l'amplitude du mouvement oscillatoire. L'invention consiste également à commander l'activation du dispositif de commande de pas sur la base du taux de changement déterminé de l'amplitude du mouvement oscillatoire.
