Abstract
Provided is a system for determining a soiling state of a wind turbine rotor blade. The system includes a pressure sensor adapted to measure a plurality of pressure values corresponding to a plurality of different heights above a trailing edge region of the wind turbine rotor blade, and a processing unit in communication with the pressure sensor and adapted to determine the soiling state of the wind turbine rotor blade by estimating an air flow velocity distribution above the trailing edge region of the wind turbine rotor blade based on the plurality of pressure values. Furthermore, a corresponding method of determining a soiling state of a wind turbine rotor blade is described.
