Control of wind park noise emission

Abstract

According to the present invention is provided a method of control of noise emission from a wind park in operation, the wind park comprising a plurality of wind turbines. The method comprises the steps of • providing measurements of at least one wind speed and of at least one wind direction to a park noise emission emulation module including for each of two or more of the plurality of wind turbines a wind turbine noise emission model being suitable for producing a prediction of noise emission from the wind turbine as a function of at least one operational characteristic, the geographical position of each of the plurality of wind turbines, and the geographical position of at least one noise immission point, • emulating the noise level at the at least one noise immission point as a result of noise emitted by the plurality of wind turbines, and • controlling the operation of the wind park from the result of the emulation so as to prevent the noise level at the at least one noise immission point from exceeding a predetermined threshold level. Furthermore, the invention relates to a wind park.
