| description | Ice detection method and system in a wind turbine with a plurality of blades (10) and a generator (11). The method measures the temperature, humidity and angular velocity (VG) of the generator (11). The method includes processing said speed (VG) to obtain the frequency spectrum; identifying a frequency band associated with the characteristic frequency of the blade (10) in said spectrum; applying a Kalman filter on said band to identify the instantaneous vibration frequency; comparing said instantaneous frequency with a reference frequency corresponding to the natural frequency without ice; determine the power produced by the wind turbine (1), estimate the producible power, compare both powers, and determine the presence of ice if the instantaneous and reference frequency are different, if the measured power is less than the estimated power and if the temperature and humidity are conducive to icing.

Método y sistema de detección de hielo en un aerogenerador con una pluralidad de palas (10) y un generador (11). En el método se miden la temperatura, la humedad y la velocidad (VG) angular del generador (11). El método incluye procesar dicha velocidad (VG) para obtener el espectro frecuencial; identificar una banda de frecuencias asociada a la frecuencia característica de la pala (10) en dicho espectro; aplicar un filtro de Kalman sobre dicha banda para identificar la frecuencia de vibración instantánea; comparar dicha frecuencia instantánea con una frecuencia de referencia correspondiente a la frecuencia natural sin hielo; determinar la potencia producida por el aerogenerador (1), estimar la potencia producible, comparar ambas potencias, y determinar la presencia de hielo si la frecuencia instantánea y de referencia son diferentes, si la potencia medida es menor que la estimada y si la temperatura y la humedad son propicias para la formación de hielo. |
