摘要
The invention relates to the field of wind turbines, in particular to a measuring system (200) and to a measuring method for detecting the accumulation of ice on a rotor blade (108) of a wind turbine, and to a wind turbine (100) with this measuring system (200). The measuring system (200) comprises a transmitter unit (210) for emitting waves in the direction of the rotor blade (108) of the wind turbine, a receiving unit (220) for receiving waves reflected at the rotor blade (108) of the wind turbine, and an evaluation unit (230) for evaluating the reflected waves in order to detect the accumulation of ice. The transmitter unit (210) is configured to emit waves with a wavelength which corresponds to a lattice vibration of ice crystals. The invention makes available an improved measuring system (200) and a measuring method for detecting the accumulation of ice on a rotor blade (108) of a wind turbine.
