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.
Claims12
A method of controlling a wind turbine having a rotor, the method comprising:
- determining a rotor noise contribution based on an actual rotor operational state;
- determining auxiliary noise contributions from a plurality of 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;
- and
- adapting a limit value of at least one operational parameter and/or a respective operational state of at least one of the plurality of auxiliary components depending on the comparing, wherein,
- when less performance of a first auxiliary component is sufficient and/or demanded, the method comprises:
- decreasing energy supply to the first auxiliary component, thereby decreasing capacity and/or performance and/or efficiency and/or noise of the first auxiliary component;
- and
- increasing energy supply to a second auxiliary component, thereby increasing capacity and/or performance and/or efficiency and/or noise of the second auxiliary component.
