Abstract: A wind turbine is disclosed which comprises a control system configured to execute at least one ice removal routine which comprises a heating stage of at least one of the blades (3), and a mechanical removal ice stage. A wind turbine removing ice method is also disclosed which comprises a stage wherein the presence of ice is detected on at least one of the blades and, once said presence of ice is detected, comprises a stage wherein at least one ice removal routine is activated which comprises, in turn, a heating stage of at least one of the blades and a mechanical removing ice stage on at least said blade.

Abstract: A wind turbine control method involves calculating a value indicative of a misalignment ? 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 ? of the wind turbine is above a first predefined misalignment threshold value. A value of a blade pitch angle ? 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 ?.

Abstract: The present invention relates to a blade assembly method on a rotor hub of a wind turbine wherein the maximum torque supported by the gearbox is greater in one direction than in other (positive in the invention instead of negative) selecting an appropriate direction for rotating the hub and an appropriate side for connecting each blade.

Abstract: The invention relates to a control method for wind turbines provided with a blade pitch angle control system and which are determined to be positioned in a misaligned manner with respect to the direction of incident wind. The method described herein makes use of a series of data and measurements captured in the wind turbine itself or its surroundings to process said data and generate by means of a series of processes and calculations a series of values which are used in commands on the wind turbine blade pitch angle control system to prevent anomalies and/or increase the efficiency thereof in said situation.

Abstract: A wind turbine control method is described based on the performance of various measurements of the oscillations of the nacelle of the wind turbine for the purpose of carrying out a series of calculations, the results of which allow parameterization of certain actions on different wind turbine elements in order to dampen oscillations. In summary, it may be said that the object of the invention described herein is a wind turbine control method whereby the oscillations of the nacelle of the wind turbine are dampened in the presence of voltage dips in particular and, in general, in any event that is susceptible of reducing active current generation capacity.
