摘要： The present invention describes a wind turbine comprising a hub, at least one blade and at least one pitch bearing to connect the at least one blade to the hub, the at least one pitch bearing comprising at least an inner ring and an outer ring, and at least a rolling race, wherein the wind turbine further comprises at least a tensioning system configured to exert a radial compression force to at least a part of the outer ring of the at least one pitch bearing, thus increasing the resultant stiffness of the at least one pitch bearing.

摘要： A wind turbine control method involves calculating a value indicative of a misalignment φ of the wind turbine on a basis of at least one signal indicative of wind direction. A determination is made as to whether the value indicative of the misalignment φ of the wind turbine is above a first predefined misalignment threshold value. A value of a blade pitch angle β is adapted. At least one of the blades of the wind turbine is rotated about its longitudinal axis on the basis of the adapted value of the blade pitch angle β.

摘要： A wind turbine includes a hub, at least one blade and at least one pitch bearing to connect the at least one blade to the hub. The at least one pitch bearing has at least an inner ring and an outer ring, and at least a rolling race. The wind turbine further includes at least a tensioning system configured to exert a radial compression force to at least a part of the outer ring of the at least one pitch bearing, thus increasing the resultant stiffness of the at least one pitch bearing.
