Wind turbine rotor blade, wind turbine and method of detecting ice on the wind turbine rotor blade

摘要

A wind turbine rotor blade, a wind turbine and a method of detecting ice on the wind turbine rotor blade are provided. The wind turbine rotor blade includes an ice detection system which detects ice on a surface of the wind turbine rotor blade, wherein the ice detection system includes an arrangement of at least one ice detection sensor provided on or at least partly within the wind turbine rotor blade, and wherein each ice detection sensor is configured to measure at least one parameter characterizing ice formation on the wind turbine rotor blade and to output a corresponding measurement signal reflecting the at least one parameter. lee formed on the surface of the wind turbine rotor blade can be detected in a more reliable manner and can be measured in terms of ice growth rate by measuring the change in the ice thickness over time.
