Abstract[English]
Aspects of the invention relate to a method of controlling a wind turbine comprising a rotor and a plurality of rotor blades. The method comprises: receiving a plurality of blade flap load signals indicative of measured flap loading on respective rotor blades, each blade flap load signal being received from a blade flap load sensor of a respective rotor blade; determining an average blade flap load signal based, at least in part, on the plurality of blade flap load signals; and determining a maximum thrust level for a thrust limit controller based on the average blade flap load signal and a reference load value that is indicative of a maximum allowable variation of the average blade flap load signal from a normal value.[French]
Des aspects de l'invention concernent un procédé de commande d'une éolienne comprenant un rotor et une pluralité de pales de rotor. Le procédé consiste à : recevoir une pluralité de signaux de charge de volet de pale indiquant une charge de volet mesurée sur des pales de rotor respectives, chaque signal de charge de volet de pale étant reçu en provenance d'un capteur de charge de volet de pale d'une pale de rotor respective ; déterminer un signal de charge de volet de pale moyen sur la base, au moins en partie, de la pluralité de signaux de charge de volet de pale ; et déterminer un niveau de poussée maximal pour un dispositif de commande de limite de poussée sur la base du signal de charge de volet de pale moyen et d'une valeur de charge de référence qui indique une variation admissible maximale du signal de charge de volet de pale moyen à partir d'une valeur normale.
