1. A method of detecting an adjustment fault related to a wind turbine rotor blade mounted at a wind turbine rotor and comprising an adaptable flow regulating device, the method comprising:
estimating a first quantity indicative of a change of a driving impact of wind on the wind turbine rotor based on at least two settings of the adaptable flow regulating device that is installed on a surface of the wind turbine rotor blade;
determining a second quantity indicative of a desired change of the driving impact on the wind turbine rotor to change a value of a rotor speed to a reference value of the rotor speed; and
indicating an adjustment fault based on a comparison of the first quantity with the second quantity.
