Abstract[English]
The invention provides a controller for a wind turbine having three rotor blades, the controller being for controlling activation of individual pitch control of the rotor blades. The controller is configured to receive a flap load signal, from a flap loading sensor of each of the three 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 statistical dispersion parameter of flap loading for each of the rotor blades, the statistical dispersion parameters being indicative of a wind event in a wind field in which the wind turbine operates. The controller is configured to control activation of individual pitch control based on the respective statistical dispersion parameters.[French]
L'invention concerne un dispositif de contrôle destiné à une éolienne ayant trois pales de rotor, ledit dispositif de contrôle étant destiné à commander l'activation d'un contrôle à calage variable de pale individuel des pales de rotor. Le dispositif de contrôle est conçu pour recevoir un signal de charge de volet, à partir d'un capteur de chargement de volet de chacune des trois pales de rotor, indicatif d'un chargement de volet sur chacune des pales de rotor respectives. Le dispositif de contrôle est conçu pour déterminer, sur la base des signaux de charge de volet reçus, un paramètre de dispersion statistique de chargement de volet pour chacune des pales de rotor, les paramètres de dispersion statistique indiquant un événement de vent dans un champ de vent dans lequel fonctionne l'éolienne. Le dispositif de contrôle est conçu pour commander l'activation d'un contrôle à calage variable de pale individuel sur la base des paramètres de dispersion statistique respectifs.
