Wind turbine system and method for controlling a wind power installation

Thus, a wind turbine (100) with a control unit (200) is provided for controlling the wind turbine in a first, second and third mode. The control unit (200) controls the wind energy system in the first mode with a first performance curve. The control unit (200) controls the wind turbine in a second mode with a second power curve, wherein the second mode is a noise-reduced operation of the wind turbine. The control unit (200) controls the wind power plant in a third mode from the second mode. The third mode is activated when a wind speed exceeds a first threshold value. The first threshold value represents that the wind speed at which the acoustic emissions generated by the wind turbine are reduced to a relevant immission than the ambient noise.
