SYSTEMS AND METHODS FOR ATTENUATING NOISE IN A WIND TURBINE

摘要

A wind turbine having an attenuating unit is presented. One embodiment of the wind turbine includes a tower and a power unit disposed at a first end of the tower. The wind turbine further includes the attenuating unit that is operatively coupled to at least one of the tower and the power unit and configured to attenuate at least the portion of the vibrational bending waves having a frequency above a threshold frequency to reduce the tonal noise of the wind turbine.
