Abstract

In one aspect, a method for controlling a wind turbine based on an identified surface condition of a rotor blade may include monitoring an operating parameter of the wind turbine to obtain parameter data related to the operating parameter as an operating input of the wind turbine changes, analyzing the parameter data to identify a roughness state of the rotor blade and performing a corrective action in response to the identified roughness state.
