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.
