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 (α), 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 (α) 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.

Control method for a wind turbine which comprises the steps of obtaining a first signal regarding the azimuthal position for each blade, obtaining at least one signal indicative of wind speed, and calculating a blade pitch angle control term. The step of calculating the blade pitch angle control term comprises the use of at least one function dependent on the at least one signal indicative of wind speed and the at least one function dependent on the at least one signal indicative of wind speed includes an increasing piece within a range of wind speed values below a nominal wind speed.
摘要:
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.
