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.
Claims24
Wind turbine control method, wherein the wind turbine comprises:
- a nacelle that comprises a longitudinal direction, and
- an orientation system,
- wherein the method comprises the following steps:
- a step of gathering:
- values indicative of wind direction with respect to the longitudinal direction of the nacelle, and
- values indicative of efficiency of the wind turbine corresponding to each value indicative of wind direction,
- a step of calculation of a correction value of the orientation system according to the values indicative of wind direction and the values indicative of efficiency of the wind turbine, and
- a step of correction of the orientation of the nacelle according to the correction value of the orientation system, and
- wherein the step of calculation of the correction value of the orientation system comprises in turn the following sub-steps:
- a sub-step of calculation of fitting parameters to a predetermined function, for the adjustment of the values indicative of wind direction and of the values indicative of efficiency of the wind turbine to the predetermined function, and
- a sub-step of calculation of the correction value of the orientation system according to at least one of the fitting parameters calculated in the preceding sub-step.
Wind turbine which comprises:
