Measuring system and method for detecting ice accumulation on wind turbine rotor blades

摘要

The invention relates to the field of wind turbines, in particular a measuring system (200) and a measuring method for detecting ice accumulation on a wind turbine blade (108), and a wind turbine (100) with this measuring system (200). The measuring system (200) comprises a transmitting unit (210) for emitting waves in the direction of the wind turbine rotor blade (108), a receiving unit (220) for receiving waves reflected at the wind turbine rotor blade (108), and an evaluation unit (230). to evaluate the reflected waves to detect ice accumulation. The transmitting unit (210) is arranged to emit waves having a wavelength corresponding to a lattice vibration of ice crystals. The invention provides an improved measurement system (200) and a measurement method for detecting ice accumulation on a wind turbine rotor blade (108).
