  • Patent number: 11168664
    Abstract: Controlling a wind turbine comprising a wind sensor, a number of pitch-adjustable rotor blades, a yawing system, and a control system for yawing the wind turbine rotor relative to the wind and for changing the pitch of the rotor blades. A wind parameter is measured by the wind sensor, and is indicative of the wind speed and/or the wind direction relative to the wind turbine. At least a first and a second set of wind correction parameters for different production modes of the wind turbine are obtained. The production mode of the wind turbine is then determined, which may be one of at least normal operation or non-production, and the measured wind parameter is then adjusted as a function of the set of wind correction parameters corresponding to the production mode at the time of adjusting. Hereby a more precise wind parameter is obtained which can be used in the controlling of the turbine.

  • Patent number: 11136110
    Abstract: A pitch control system characterized by a hub with at least two blade housings on the hub that are disposed around the hub axis. The blade housings have corresponding blades that engage with them. The blades spiral along housing longitudinal axes toward and away from the hub axis about a segment of helical path to effect a change in the pitch of each blade. One or more elastic members draw the blades toward the hub axis, either directly or indirectly. There are pitch mechanisms effective to facilitate blades to spiral around housing-longitudinal axes. A blade will spiral away from the hub axis when the centrifugal force exerted on the blade exceeds the opposing elastic force in the housing-longitudinal direction (neglecting other forces). Conversely, blades spiral toward the hub axis when said centrifugal force is less than said elastic force. There is an imaginary plane orthogonal to the hub axis. Housing-longitudinal axes have angles with respect to the imaginary plane of not more than 30 degrees.
