Abstract: The invention provides a method of identifying recurrent free-flow wind disturbances associated with a wind turbine. The method comprises monitoring a signal indicative of a parameter associated with operation of the wind turbine, determining an expected signal of the parameter based on the monitored signal, determining a difference between values of the monitored signal and the determined expected signal, and correlating the determined differences with yaw position of a nacelle of the wind turbine. The method includes determining, based on the correlated differences, unexpected values of the parameter for different yaw positions, and identifying, based on a frequency of occurrence of the determined unexpected values, a recurrent free-flow wind disturbance associated with a yaw position of the nacelle.

Abstract: A method of calibrating a reference of a wind turbine. The method comprises monitoring performance of the wind turbine over a calibration period to generate performance data, wherein the calibration period comprises a series of sub-periods. The reference is calibrated by: setting the reference on the basis of the performance data; and, for each sub-period: determining a sub-period value on the basis of the performance data generated during that sub-period, comparing the sub-period value with the reference, and updating the reference with the sub-period value if the comparison shows that a performance of the wind turbine indicated by the sub-period value is better than a performance of the wind turbine indicated by the reference. The comparison and updating steps enable the reference to more accurately reflect more recent performance of the wind turbine. The method can also be reliably used in freezing temperatures.

Abstract: The present invention relates to a method of operating a wind turbine with an operational parameter where values of the operational parameter are obtained by different sensors and compared to determine the validity of the value. A first value and a second value of the operational parameter are obtained different sensors and validated by comparing the two values. The wind turbine being operated using a validated value as the operational parameter. The two sensors are selected among a trained machine learning model, a reference sensor and a computerized physical model.
