[0003] This undesired vibration can create a load on the wind turbine tower and other components of the wind turbine, which can lead to fatigue damage and reduced service life, the slow increase in damage in the wind turbine tower will eventually lead to the shutdown of the wind turbine
This undesired vibration also adds uncertainty to the prediction of wind turbine load outcomes

Embodiment Construction

[0020] FIG. 1 is a schematic diagram of an embodiment of a wind turbine 100 . Wind turbine 100 includes a nacelle 102 , a tower 104 , a rotor 106 having at least one rotor blade 108 and a hub 110 . Exemplary towers 104 include lattice towers and tubular towers. The nacelle 102 is mounted atop a tower 104, a portion of which is shown in FIG. 1 . The rotor blades 108 are connected to a hub 110 .

[0021] FIG. 2 is a schematic diagram of an embodiment of a system 111 including a nacelle 102 , a tower 104 and a hub 110 . Housed within the nacelle 102 is a control panel 112 including a processor 113 . The term processor used here is not limited to those integrated circuits as processors in the prior art, but should be broadly understood as controllers, microcontrollers, microcomputers, programmable logic controllers, application-specific integrated circuits and any other programmable circuit.

[0022] Hub 110 includes a variable blade pitch drive 114 . Nacelle 102 also houses...

Abstract

A method for damping a displacement of a wind turbine tower includes controlling a frequency of oscillation of the wind turbine tower by coupling one of a first beam and a water tank to a plurality of surfaces inside the wind turbine tower.

Description

Background technique [0001] The present invention relates generally to wind turbines and, more particularly, to systems and methods for inhibiting wind turbine tower displacement. [0002] Undesirable vibrations may occur in the wind turbine tower of a wind turbine used to generate electricity. Whether such undesired vibrations occur depends on the design of the wind turbine tower and various weather conditions. [0003] This undesired vibration can create a load on the wind turbine tower and other components of the wind turbine, which can lead to fatigue damage and reduced service life, the slow increase in damage in the wind turbine tower will eventually lead to the shutdown of the wind turbine . This undesired vibration also adds an element of uncertainty to the prediction of wind turbine load outcomes. Contents of the invention [0004] In one aspect, a method of dampening wind turbine tower displacement is provided. The method includes controlling a vibration freque...
