Title
(EN) METHOD AND SYSTEM FOR DETECTING A WIND GUST THAT AFFECTS A WIND TURBINE
(FR) PROCÉDÉ ET SYSTÈME DE DÉTECTION D'UNE RAFALE DE VENT AFFECTANT UNE ÉOLIENNE
Abstract
(EN)
It is described a method for detecting a wind gust that affects a wind turbine (100) comprises two or more blades (114) which are coupled to a connection means (112) so that the blades (114) are essentially arranged in a common plane (P). The method comprising: i) measuring (110) an event that at least one blade (114) is at least partially out of the plane (P) to obtain a measurement signal (M-A), ii) providing (120) the measurement signal (M-A) as a measurement input signal (MI) to an evaluation algorithm (131), iii) elaborating (130) a detection result (150) from the measurement input signal (MI) using the evaluation algorithm (131), and iv) comparing the detection result (150) with a predefined wind gust threshold value (h) to determine (140), if a wind gust is detected. Furthermore, a wind gust detection system, a wind turbine that comprises said system, and a wind turbine operating method are described.

L'invention concerne un procédé de détection d'une rafale de vent qui affecte une éolienne (100) comprenant au moins deux pales (114) qui sont couplées à un moyen de liaison (112) de sorte que les pales (114) soient essentiellement agencées dans un plan commun (P). Le procédé comprend les étapes consistant à : i) mesurer (110) un événement où au moins une pale (114) est au moins partiellement hors du plan (P) pour obtenir un signal de mesure (M-A), ii) fournir (120) le signal de mesure (M-A) en tant que signal d'entrée de mesure (MI) à un algorithme d'évaluation (131), iii) élaborer (130) un résultat de détection (150) à partir du signal d'entrée de mesure (MI) à l'aide de l'algorithme d'évaluation (131), et iv) comparer le résultat de détection (150) avec une valeur seuil de vent (h) prédéfinie pour déterminer (140), si une rafale de vent est détectée. En outre, l'invention concerne un système de détection de rafale de vent, une éolienne qui comprend ledit système, et un procédé de fonctionnement d'éolienne.
