Estimating the term…
A method and a device for determining an iced condition of a blade of a wind turbine is provided. A target nacelle displacement along a rotational axis is acquired as a function of at least one predetermined parameter in an ice-free condition of the blade; an actual nacelle displacement along the rotational axis is measured by a displacement sensor; and the iced condition of the blade is determined if a difference between the target nacelle displacement and the actual nacelle displacement exceeds a predetermined threshold value.
A method of determining an iced condition of a blade of a wind turbine, the wind turbine comprising a nacelle and a hub, the hub having the blade and being mounted to the nacelle rotatably about a rotational axis, the method comprising:
