Abstract
A method for noise-reduced operation a wind is provided. The method includes determining a wind speed during normal operation of the wind turbine and determining a weighted rotor speed setpoint for a rotor of the wind turbine so that a noise emission of the wind turbine for the wind speed is reduced compared to nominal noise emission of the wind turbine at the wind speed. Using the weighted rotor speed setpoint, a torque setpoint for a power conversion assembly connected to the rotor is determined. The torque setpoint is applied to the power conversion assembly to control the wind turbine.

The method of claim 8, wherein calculating the first rotor setpoint results in a value that is lower than a rotor speed corresponding to maximum power uptake of the rotor at the wind speed.
A method for noise-reduced operation of a wind turbine, comprising:
- determining an expected wind speed;
- determining, using the expected wind speed, a weighted rotor speed setpoint for a rotor of the wind turbine that is lower than a rated rotor speed of the rotor;
- and,
- using the weighted rotor speed setpoint as a command variable for a rotor speed of the rotor used as a controlled variable for controlling the wind turbine during partial-load operation of the wind turbine.
A control system for controlling a wind turbine, comprising:
