Control Method for a wind turbine

摘要

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.

1. Control method for a wind turbine of the type comprising at least:
a tower, a rotor with a plurality of blades, each comprising respective actuators, configured to modify the blade pitch angle of each blade, and a control unit,
wherein the method comprises the following steps: obtaining a first signal regarding the azimuthal position for each blade, obtaining at least one signal indicative of wind speed, calculating a blade pitch angle control term for each blade in accordance with the azimuthal position of each blade and of at least one signal indicative of wind speed, for the purpose of increasing the blade pitch angle, wherein the step of calculating the blade pitch angle control term comprises the use of the at least one function dependent on the at least one signal indicative of wind speed, and in that 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.
