Abstract[English]
The invention provides a controller for a wind turbine having a plurality of rotor blades. The controller is for controlling activation of individual pitch control of the rotor blades. The controller is configured to receive a flap load signal, from a blade load sensor of each of the plurality of rotor blades, indicative of flap loading on each of the respective rotor blades. The controller is configured to determine, based on the received flap load signals, a standard deviation parameter indicative of volatility of loading on the rotor blades of the wind turbine. The controller is configured to control activation of individual pitch control based on the determined standard deviation parameter.[French]
L'invention concerne un dispositif de commande pour une éolienne dotée d'une pluralité de pales de rotor. Le dispositif de commande est destiné à commander l'activation d'une régulation par contrôle individuel du pas des pales de rotor. Le dispositif de commande est configuré pour recevoir un signal de charge de volet, à partir d'un capteur de charge de pale de chacune des trois pales de rotor, indicatif d'un chargement de volet sur chacune des pales de rotor respectives. Le dispositif de commande est configuré pour déterminer, sur la base des signaux de charge de volet reçus, un paramètre d'écart type indiquant la volatilité du chargement sur les pales de rotor de l'éolienne. Le dispositif de commande est configuré pour commander l'activation d'une régulation par contrôle individuel du pas sur la base du paramètre d'écart type déterminé.
