  • Patent number: 10794360
    Abstract: Method of reducing loads acting on a wind turbine yaw system in a wind turbine comprising a nacelle (2), a rotor which comprises at least one rotor blade (3) with a pitch control system and further comprising a yaw system that comprises the steps of detecting a yaw misalignment (?), enabling a yaw maneuver and performing a pitch control in order to reduce a yaw moment (Mz) acting on the wind turbine once the yaw misalignment (?) is detected and prior to enabling the yaw maneuver. Thus, when a yaw movement to reduce the yaw misalignment is commanded, the yaw moment (Mz) due to aerodynamic forces has been reduced by means of the pitch control and undesired yaw movements are prevented.

  • Patent number: 10330080
    Abstract: The present invention relates to a wind turbine control method that makes it possible to detect misalignments in said wind turbine with respect to the wind direction, wherein once these situations are detected, the control method of the present invention makes it possible to perform an automatic correction of the control parameters and to return the wind turbine to its optimal operating point, together with the associated wind turbine.

  • Patent number: 9903340
    Abstract: It describes a control system and method of a wind turbine to operate it in optimum output operation in situations wherein incidents occur. To do this a series of measurements are taken of elements in the surrounding area of the wind turbine which incide it to be able to calculate blade pitch angle set-points to reorientate or move the same until positions designated in accordance with said pitch angle set-point. The method described here is based, among other parameters, on the wind speed; so that it provides for at least two possible control situations in accordance with said speed: one when the speed is less than a rated value and another when said speed is greater than a rated value.

  • Publication number: 20120139240
    Abstract: Loads reduction method in a wind turbine for power-grid disconnection during a wind gust, which uses a control system made up of three loops used to correct the speed at which the wind turbine blades are moved to the feathered position throughout a controlled emergency stop, with a non-linear law that takes into account blade position, tower vibrations and generator rotation speed limits.
