METHOD FOR OPERATING A WIND TURBINE AND DEVICE FOR THE OPEN-LOOP AND/OR CLOSED-LOOP CONTROL OF A WIND TURBINE AND CORRESPONDING WIND TURBINE HAVING A ROTOR AND A GENERATOR DRIVEN BY THE ROTOR FOR GENERATING ELECTRICAL POWER
METHOD FOR OPERATING A WIND TURBINE AND DEVICE FOR THE OPEN-LOOP AND/OR CLOSED-LOOP CONTROL OF A WIND TURBINE AND CORRESPONDING WIND TURBINE HAVING A ROTOR AND A GENERATOR DRIVEN BY THE ROTOR FOR GENERATING ELECTRICAL POWER
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.
