A method of controlling a wind turbine includes obtaining weather data indicative of one or more weather conditions at the wind turbine, estimating wake profiles based on the obtained weather data, estimating far-field sound propagation in a direction of a noise sensitive site based on the estimated wake profiles, generating a yaw signal, wherein the yaw signal controls the yaw of a nacelle relative to a tower of the wind turbine, estimating a noise level at the noise sensitive site, and adjusting the yaw signal if the estimated noise level at the noise sensitive site exceeds a threshold noise level.

System and methods for controlling noise propagation of wind turbines

A method for controlling a wind farm includes: receiving temperature data associated with a plurality of locations along a sound path between the wind farm and a sound immission point from one or more sensors; estimating a propagation characteristic of the sound path based at least in part on the temperature data; predicting a noise level at the sound immission point based at least in part on the propagation characteristic; determining a control signal for one or more wind turbines in the wind farm based at least in part on the noise level; and using the control signal to control the one or more wind turbines.
