Embodiment Construction

[0083] figure 1 is a schematic diagram of an exemplary wind turbine 100 . In the exemplary embodiment, wind turbine 100 is a horizontal axis wind turbine. Alternatively, wind turbine 100 may be a vertical axis wind turbine. In the exemplary embodiment, wind turbine 100 includes a tower 102 extending from and coupled to a support surface 104 . Tower 102 may be coupled to surface 104 , for example, with anchor bolts or via foundation mounts (neither shown). Nacelle 106 is coupled to tower 102 and rotor 108 is coupled to nacelle 106 . Rotor 108 includes a rotatable hub 110 and a plurality of rotor blades 112 coupled to hub 110 . In the exemplary embodiment, rotor 108 includes three rotor blades 112 . Alternatively, rotor 108 may have any suitable number of rotor blades 112 that enables wind turbine 100 to function as described herein. Tower 102 may have any suitable height and / or configuration that enables wind turbine 100 to function as described herein.

Abstract

The present invention provides a structural section for a tower mast and a method for manufacturing the section. The section comprises a sheet comprising a first end, a second end and a body disposed between the first end and the second end. A plurality of profiles are formed within the body, each profile comprising a deformation offset from the body. A fastener is configured to contact the first end to the second end to facilitate forming the body about a longitudinal axis and facilitate radially positioning the plurality of profiles around the longitudinal axis.

Description

technical field [0001] The subject matter described herein relates to wind turbines, and more particularly, to structural sections for wind turbine towers. Background technique [0002] Generally, a wind turbine includes a rotor including a rotatable hub assembly having a plurality of blades. The blades convert wind energy into a mechanical rotational torque that drives one or more generators via the rotor. The generator is sometimes, but not always, rotationally coupled to the rotor through a gearbox. The gearbox boosts the inherently low rotational speed of the rotor for the generator to efficiently convert the rotating mechanical energy into electrical energy, which is fed into the utility grid via at least one electrical connection. The rotor, generator, gearbox and other components are typically mounted within a housing or nacelle positioned on a foundation comprising a truss or tubular tower. [0003] Wind turbine towers typically include a plurality of circular seg...
