Title (EN) VARIABLE SPEED CONTROL OF WIND TURBINE GENERATOR BASED ON ESTIMATED TORQUE
(FR) COMMANDE DE VITESSE VARIABLE D'UN GÉNÉRATEUR ÉOLIEN SUR LA BASE D'UN COUPLE ESTIMÉ
Abstract:
(EN) A system for controlling a wind turbine generator includes a rotor blade assembly having rotor blades and a pitch actuator to control a pitch of the rotor blades, a power generator coupled to the rotor blade assembly, and a main controller. The main controller is configured to control the aerodynamic torque applied on the rotor blades based on pitch control commands, and separately configured to control a generator speed of the power generator based on torque control commands. The system further includes a pitch controller configured to receive pitch calculation information from the main controller, calculate the pitch control commands, and return the pitch control commands to the main controller. The system further includes a torque controller configured to receive torque calculation information from the main controller, calculate the torque control commands, and return torque control commands to the main controller.
(FR) L'invention concerne un système de commande d'un générateur éolien, comprenant un ensemble rotor avec pales ayant des pales de rotor et un actionneur de pas pour commander un pas des pales de rotor, un générateur d'électricité couplé à l'ensemble rotor avec pales, et un dispositif de commande principal. Le dispositif de commande principal est conçu pour commander le couple aérodynamique appliqué aux pales de rotor sur la base d'instructions de commande de pas, et conçu de manière distincte pour commander une vitesse du générateur d'électricité sur la base d'instructions de commande de couple. Le système comprend en outre un dispositif de commande de pas conçu pour recevoir des informations de calcul de pas en provenance du dispositif de commande principal, calculer les instructions de commande de pas, et renvoyer les instructions de commande de pas au dispositif de commande principal. Le système comprend en outre un dispositif de commande de couple conçu pour recevoir des informations de calcul de couple provenant du dispositif de commande principal, calculer les instructions de commande de couple, et renvoyer des instructions de commande de couple au dispositif de commande principal.
