Abstract
There is presented a method () for controlling a wind turbine (), wherein said wind turbine comprises a wind turbine rotor () with one or more blades (), wherein the wind turbine has a rated angular rotation speed () of the wind turbine rotor, said method comprising providing () an estimated drop size () of rain drops impinging on the one or more blades, determining () whether an entry criterion for operation according to a reduced mode is fulfilled, wherein said determining is based at least partially on the estimated drop size (), controlling () the wind turbine according to the reduced mode if the entry criterion is fulfilled, wherein in the reduced mode an angular rotation speed of the wind turbine rotor is limited below an angular rotation speed threshold (), wherein the angular rotation speed threshold is smaller than the rated angular rotation speed of the wind turbine.
