    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 correcting a pitch angle deviation of a blade of a wind turbine is provided. First blade load measurements measured when the wind turbine was operating in a first operational mode are provided, and used to determine calibration parameters. Second blade load measurements measured when the wind turbine was operating in a second operational mode are provided, and the calibration parameters applied to determine calibrated blade load measurements. A pitch angle deviation of at least one blade of the turbine is estimated based on an identified difference between the calibrated blade load measurements, and a pitch angle is adjusted to correct for the pitch angle deviation.

    Abstract: A method for determining a relative position of wind sensors on a wind turbine comprising: obtaining wind data from each of at least two wind sensors installed on a wind turbine at a location where airflow is affected by a rotor of the wind turbine, the obtaining occurring while the rotor is rotating, identifying oscillations in the wind data from each of the wind sensors, determining a phase or amplitude difference between the oscillations, and determining a relative position of the wind sensors based on the phase or amplitude difference.
