Abstract[English]
A method of operating a wind turbine at reduced power output, the wind turbine comprising a rotor coupled to a gearbox, the method comprising: receiving a de-rating request, the de-rating request indicating a reduced power output level of the wind turbine; in response to the de-rating request, reducing the power output level of the wind turbine; as the power output level reduces, monitoring an operating parameter of the wind turbine to detect a backlash risk condition of the gearbox; and in response to the detection of a backlash risk condition, modifying the reduction of the power output level to reduce the risk of backlash from occurring in the gearbox.[French]
L'invention concerne un procédé de fonctionnement d'une éolienne à puissance de sortie réduite, ladite éolienne comprenant un rotor couplé à une boîte de vitesses. Le procédé consiste à : recevoir une demande de déclassement indiquant un niveau de sortie de puissance réduite de l'éolienne; en réponse à la demande de déclassement, réduire le niveau de sortie de puissance de l'éolienne; lorsque le niveau de sortie de puissance diminue, surveiller un paramètre de fonctionnement de l'éolienne pour détecter un état de risque de jeu de la boîte de vitesses; et en réponse à la détection d'une condition de risque de jeu, modifier la réduction du niveau de sortie de puissance pour réduire le risque de jeu de se produire dans la boîte de vitesses.
