    摘要: In one aspect, a method for controlling the amplitude modulation of the noise generated by wind turbines is disclosed. The method may include determining a rotor position of a first wind turbine, determining a rotor position of a second wind turbine, determining if the first and second wind turbines are operating in-phase and, in the event that the first and second wind turbines are operating in-phase, adjusting an operating condition of at least one of the first wind turbine and the second wind turbine so that the first and second wind turbines operate out-of-phase.

    摘要: A shroud for a wind turbine and a method for modifying performance of a wind turbine are disclosed. The wind turbine includes a rotor mounted to a nacelle, the rotor including a plurality of rotor blades and defining an outer diameter. The shroud is positioned downstream of the rotor in an air flow direction, and has an inner diameter of less than the outer diameter of the rotor.

    摘要: A rotor blade for a wind turbine is disclosed. The rotor blade may generally include a body extending between a blade root and a blade tip. The body may include a pressure side and a suction side extending between a leading edge and a trailing edge. In addition, the rotor blade may include a nozzle mounted on or within the body. The nozzle may include an inlet, an outlet and a converging section between the inlet and the outlet. The converging section may be configured to accelerate a flow of air through the nozzle such that an ultrasonic sound emission is produced.

The method may include determining a sound characteristic of a turbine sound wave generated by a wind turbine and generating an additive sound wave based on the sound characteristic such that a resultant sound wave is produced having a peak-to-peak amplitude that is smaller than a peak-to-peak amplitude of the turbine sound wave.
