Abstract:
1. A method for calibrating a wind turbine sensor placed on a component of a wind turbine, the wind turbine having a rotor with at least one wind turbine blade, the method comprising: pitching, at time intervals, the at least one wind turbine blade according to a predetermined pitch movement which induces a vibratory motion of the at least one wind turbine blade; detecting at least one vibratory response signal from the wind turbine sensor at least partly caused by the vibratory motion; determining a characteristic sensor response value as a function of the at least one vibratory response signal; determining a difference between the characteristic sensor response value and a predetermined sensor calibration parameter; and calibrating the wind turbine sensor according to the determined characteristic sensor response value in case the difference is greater than a predefined tolerance parameter.
