Abstract[English]
The invention relates to determining wind speed at a wind turbine comprising a tower and a rotor. The invention involves estimating a wind speed signal based on an estimated rotor power of the wind turbine, and obtaining a tower velocity signal indicative of a velocity of the tower in a fore-aft direction of the wind turbine. The invention involves combining the estimated wind speed signal and the tower velocity signal to determine wind speed at the wind turbine. The determined wind speed captures relatively fast changes in wind conditions, e.g. wind gusts, with minimal delay.[French]
L'invention concerne la détermination de la vitesse du vent au niveau d'une éolienne comprenant une tour et un rotor. L'invention consiste à estimer un signal de vitesse du vent sur la base d'une puissance de rotor estimée de l'éolienne, et à obtenir un signal de vitesse de tour indicatif d'une vitesse de la tour dans une direction avant-arrière de l'éolienne. L'invention consiste à combiner le signal de vitesse de vent estimé et le signal de vitesse de tour pour déterminer la vitesse du vent au niveau de l'éolienne. La vitesse de vent déterminée capture des changements relativement rapides dans des conditions de vent, par exemple des rafales de vent, avec un retard minimal.
