Abstract[English]
The invention pertains to wake steering. A second wind turbine is positioned downstream of the first wind turbine so that it can be affected by a wake of the first wind turbine. In a method of the invention, a yaw offset signal is applied to create a yaw offset between a rotor of the first wind turbine and the wind direction, and the yaw offset signal is varied based on a transfer function in response to changes in the wind direction. The transfer function comprises: a negative offset band, a negative transition, a positive offset band, a positive transition, and a dead band between the positive and negative transitions.[French]
L'invention concerne le guidage du sillage. Une seconde éolienne est positionnée en aval de la première éolienne de telle sorte qu'elle peut être affectée par le sillage de la première éolienne. Dans un procédé de l'invention, un signal de décalage de lacet est appliqué pour créer un décalage de lacet entre un rotor de la première éolienne et la direction du vent, et le signal de décalage de lacet est modifié sur la base d'une fonction de transfert en réponse à des changements dans la direction du vent. La fonction de transfert comprend : une bande de décalage négative, une transition négative, une bande de décalage positive, une transition positive et une bande morte entre les transitions positive et négative.
