Estimating the term…
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.
Control method of a wind turbine which comprises a series of blades, and a blade pitch angle control system, the method comprising the following steps:
Method according to claim 17, wherein the calculation of the blade pitch angle lower limit value βMIN comprises carrying out a comparison of the signal indicative of wind speed with a curve or table comprising a correlation between the blade pitch angle lower limit value βMIN which defines a stalling threshold and each value of the signal indicative of wind speed.
