An apparatus and a method used to determine the speed and direction of the wind experienced by a wind turbine are provided. Said apparatus comprises at least one sensor fixed to the rotor of said wind turbine, an angular sensor to measure the angular position of the rotor of said wind turbine, and a circuit which converts the relationship between the output of said at least one sensor and the output of the angular sensor into the speed and direction of the wind experienced by the wind turbine. According to the invention, the sensing apparatus can measure the wind speed and direction in three dimensions. In addition, mounting the sensors directly to the rotor of the wind turbine results in a very simple and robust installation. Mounting the sensors directly to the rotor also eliminates the turbulence from the rotor and the nacelle of the wind turbine from affecting the sensors.
L'invention concerne un procédé et un appareil servant à déterminer la vitesse et la direction du vent dans une éolienne. L'appareil comprend au moins: un capteur fixé au rotor de l'éolienne; un capteur angulaire servant à mesurer la position angulaire du rotor de l'éolienne; et un circuit qui convertit la relation entre la sortie du (des) capteur(s) et la sortie du capteur angulaire pour déterminer la vitesse et la direction du vent dans l'éolienne. Selon l'invention, le détecteur peut mesurer la vitesse et la direction du vent en trois dimensions. De plus, en montant les capteurs directement sur le rotor de l'éolienne, on réalise une installation très simple et robuste qui préserve en outre les capteurs de la turbulence générée par le rotor et la nacelle de l'éolienne.
