Abstract[English]
The invention provides a method of identifying recurrent free-flow wind disturbances associated with a wind turbine. The method comprises monitoring a signal indicative of a parameter associated with operation of the wind turbine, determining an expected signal of the parameter based on the monitored signal, determining a difference between values of the monitored signal and the determined expected signal, and correlating the determined differences with yaw position of a nacelle of the wind turbine. The method includes determining, based on the correlated differences, unexpected values of the parameter for different yaw positions, and identifying, based on a frequency of occurrence of the determined unexpected values, a recurrent free-flow wind disturbance associated with a yaw position of the nacelle.[French]
L'invention concerne un procédé d'identification de perturbations de vent à écoulement libre récurrentes associées à une éolienne. Le procédé comprend la surveillance d'un signal indicatif d'un paramètre associé au fonctionnement de l'éolienne, la détermination d'un signal attendu du paramètre sur la base du signal surveillé, la détermination d'une différence entre des valeurs du signal surveillé et du signal attendu déterminé, et la corrélation des différences déterminées avec la position de lacet d'une nacelle de l'éolienne. Le procédé comprend la détermination, sur la base des différences corrélées, des valeurs inattendues du paramètre pour différentes positions de lacet, et l'identification, sur la base d'une fréquence d'occurrence des valeurs inattendues déterminées, d'une perturbation de vent à écoulement libre récurrente associée à une position de lacet de la nacelle.
