Abstract

La présente invention concerne des dispositifs, des systèmes et un procédé de commande d'une éolienne. En particulier, la présente invention concerne un dispositif d'interférence de signal pour interférer avec un signal de vitesse fourni par un capteur de vitesse disposé pour détecter la vitesse d'une chaîne cinématique d'une éolienne. Ledit dispositif d'interférence de signal comprend un dispositif de commande d'éolienne commandant le mode de fonctionnement de l'éolienne sur la base, entre autres, d'un signal de vitesse reçu, et est configuré pour : identifier, à partir d'un signal de vent d'un capteur de vent, une variation de vent rapide s'approchant qui conduirait à une réponse de charge critique de l'éolienne, puis interférer avec le signal de vitesse par augmentation progressive du signal de vitesse à une seconde vitesse et fournir ce signal de vitesse progressivement croissant au dispositif de commande d'éolienne, ou fournir à l'unité de commande de l'éolienne le signal de vitesse non perturbé, si le signal de vent n'est pas indicateur ou ne comprend pas de manière inhérente des informations sur un changement de vent rapide.
