Abstract: The present disclosure relates to a method for operating a wind power installation, to an associated wind power installation and to a wind farm. The method comprises the following steps: determining at least two, preferably at least three and particularly preferably all the environmental parameters of the environment of the wind power installation selected from the list consisting of: turbulence intensity, air density, air temperature and shear; providing boundary conditions for operating the wind power installation, the boundary conditions containing at least one from a load boundary condition, a noise level boundary condition and a power boundary condition; adapting an operational control, in particular an operating point and/or an operating characteristic, of the wind power installation on the basis of a combination of the changes in the determined environmental parameters taking into consideration the boundary conditions.

Abstract: A method for operating a wind power installation having a rotor and a generator driven via the rotor for generating electrical power, in which provides for an adapted rotational speed of the rotor of the wind power installation for generating electrical power to be output to be specified using the adapted operational management and therefore using the air density relevant to the wind power installation, wherein, for generating optimized electrical power to be output, the adapted rotational speed is an increased rotational speed for a reduced air density or a reduced rotational speed for an increased air density, wherein additionally or alternatively a sound emission of the wind power installation is determined for the specified adapted rotational speed of the rotor using the air density relevant to the wind power installation, and the adapted rotational speed is corrected, in particular on the basis of the determined sound emission, using the air density relevant to the wind power installation.
