Abstract
A method of controlling a wind turbine having a rotor, in particular in all rotational speed regimes is provided, the method including: determining a rotor noise contribution, in particular based on an actual rotor operational state; determining auxiliary noise contributions from plural auxiliary components based on respective actual operational states; determining a total noise based on the auxiliary noise contributions and the rotor noise contribution; comparing the total noise with a noise threshold; adapting a limit value of at least one operational parameter and/or a respective operational state of at least one of the auxiliary components depending on the comparison result.
