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

摘要

The invention relates to a method for operating a wind turbine having a rotor and a generator driven by the rotor for generating electrical power, wherein, according to the invention, an adapted rotational speed of the rotor of the wind turbine is predefined using the adapted operating management and also using the air density relevant for the wind turbine in order to generate an electrical power to be output, wherein, in order to generate an optimised electrical power to be output, the adapted rotational speed is an increased rotational speed in the event of a lowered air density or same is a lowered rotational speed in the event of an increased air density, wherein, additionally or alternatively, a sound emission of the wind turbine is determined for the predefined adapted rotational speed of the rotor using the air density relevant for the wind turbine, and the adapted rotational speed is corrected, in particular based on the determined sound emission using the air density relevant for the wind turbine.
