Abstract
A nacelle for a wind turbine is provided, whereby the nacelle includes a nacelle support structure inside of the nacelle, to which at least one tuned mass damper is attached, whereby the at least one tuned mass damper is tuned to target at least one mode of motion of the nacelle in a frequency range below 50 Hz.
Claims14
A nacelle for a wind turbine, comprising:
- a housing surrounding an interior space of the nacelle;
- a nacelle support structure disposed within the interior space of the nacelle, wherein the nacelle support structure has a top side and a bottom side, and supports a drive unit of the wind turbine on the top side;
- at least one tuned mass damper disposed within the interior space of the nacelle, attached to the bottom side of the nacelle support structure, wherein the at least one tuned mass damper is tuned to target at least one mode of motion of the nacelle in a frequency range below 50 Hz, wherein the at least one tuned mass damper is attached to a rear-end portion of the nacelle support structure, the rear-end portion of the nacelle support structure being disposed behind an attachment point to a tower of the wind turbine in a direction along the nacelle from a rotor of the wind turbine to a rear-end of the nacelle, and wherein the rear-end portion hangs freely above the ground and is not directly supported by the tower.
A method comprising:
- utilizing at least one tuned mass damper located within a housing of a nacelle for a wind turbine, wherein a nacelle support structure having a top side and a bottom side is located within the housing of the nacelle and supports a drive unit of the wind turbine on the top side, the at least one tuned mass damper being attached to the bottom side of the nacelle support structure also located within the housing of the nacelle and tuned to target at least one motion of the nacelle in a frequency range below 50 Hz;
- wherein the at least one tuned mass damper is attached to a rear-end portion of the nacelle support structure, the rear-end portion of the nacelle support structure being disposed behind an attachment point to a tower of the wind turbine in a direction along the nacelle from a rotor of the wind turbine to a rear-end of the nacelle, and wherein the rear-end portion hangs freely above the ground and is not directly supported by the tower.
