Abstract
A method of adapting noise emission configurations of plural wind turbines, the method including: determining total wind turbine related noise levels at plural locations; determining, among the plural locations, a critical location having a most critical, in particular highest, total wind turbine related noise level; if the most critical total wind turbine related noise level is above a noise threshold: reducing the noise emission configuration of a wind turbine having the highest noise to power impact ratio, is provided.
Claims16
A method of adapting noise emission configuration of a plurality wind turbines, the method comprising:
- determining total wind turbine related noise levels at a plurality of locations;
- selecting a critical location from the plurality of locations that has a highest difference between the total wind turbine related noise level of a considered location and a noise threshold for the considered location, among all of the plurality of locations;
- determining that the total wind turbine related noise exceeds the noise threshold;
- selecting a wind turbine from the plurality of wind turbines that is closest to the critical location and has a highest noise to power impact ratio for reducing a noise level at the critical location;
- reducing a rotational speed setpoint of the selected wind turbine;
- and
- diverting a main noise radiation of the selected wind turbine away from the critical location introducing a yaw offset which yaws the selected turbine.
