Abstract

It is described a method for calibrating a wind direction measurement for a wind turbine (1), the method comprising: measuring plural samples of a relative wind direction (±) representing a difference angle between a real wind direction (19) and an orientation of a measurement equipment (14), in particular a direction orthogonal to a rotor blade plane (13), to obtain plural measured relative wind directions (±'); deriving a measured relative wind direction change (53, 39) based on the measured relative wind directions (±'); measuring plural samples of a performance parameter (43) indicating a performance of the wind turbine; deriving a performance change (61, 39) based on the plural samples of the performance parameter; determining a correlation value (65) between the measured relative wind direction change and the performance change; measuring further plural samples of the relative wind direction; and correcting the further measured relative wind directions based on the correlation value, to obtain corrected further measured relative wind directions (±").
