Definitions

  • the present invention relates to a method for making a wind turbine at a site of construction and to a nacelle facilitating the method. More specifically, the invention relates to a method where parts of the wind turbine including the nacelle are transported to a construction site where the wind turbine is to be erected. At this site, the nacelle is lifted and placed on top of a wind turbine tower by use of a crane.
  • Modern wind turbines comprise a tower construction which is traditionally formed by tapered round tower sections mounted on top of each other. The sections are mounted on each other in situ by use of a crane.
  • the nacelle which houses the drive train, generator, and other components, is lifted and attached to the top of the tower.
  • the nacelle is made in a factory and transported to the construction site where it is lifted in one piece to the position on top of the tower. During this operation, the wind may cause movement of the nacelle while it is suspended from a crane. The movement makes precise positioning and assembly difficult.
  • the invention in a first aspect, provides a method for making a wind turbine, the method comprising the steps of:
  • the invention provides a nacelle assembly for a wind turbine, the nacelle assembly comprising a nacelle which houses different parts of the wind turbine and which is attachable to a wind turbine tower, the assembly further comprising at least one add-on profile configured to provide a temporary change in shape of the nacelle.
  • the invention provides a lifting gear for lifting a nacelle, the lifting gear being configured to shield the nacelle and thereby reduce the drag coefficient.
  • the invention provides a wind turbine nacelle add-on configured for temporary use for amending the shape of the nacelle during lifting when the wind turbine is erected.
  • an initial aerodynamic property may be an initial drag coefficient
  • a change of the aerodynamic property may be a change of the drag coefficient
  • the wind turbine may particularly be a horizontal axis wind turbine, comprising a tower and at least one nacelle on top of the tower.
  • the tower may e.g. be a regular steel tower made from steel plates, or it could be a concrete tower or any other kind of tower construction.
  • the nacelle houses main technical parts of the wind turbine such as a gearbox, a generator, the drive train connecting the rotor to the generator via the gearbox, the low- and high-speed shafts, and a brake, etc.
  • the rotor is connected to a number of accompanying blades. Through the blades-rotor system the electrical energy is generated and further transferred to at least one power grid or the like.
  • a nacelle is typically manufactured in a factory with an initial shape, usually a rectangular box shape.
  • the nacelle is made in accordance with predefined standards in factory facilities which are often far away from the site of construction.
  • the nacelle is normally transported by truck, railway, boat, or the like, and due to transport complications, it may be an advantage to transport the nacelle in its initial shape.
  • the initial shape is typically as small as possible considering the content and functions of the nacelle and considering the need for transportation.
  • a parameter which describes the influence of the wind on the nacelle is a drag coefficient.
  • the drag coefficient is a function of parameters including the shape and size of the nacelle.
  • the lifting procedure and the transport procedure are both facilitated by a nacelle which is made with an initial aerodynamic property in which it can be transported efficiently and subsequently hoisted with a changed aerodynamic property such that the drag profile and/or back pressure is/are reduced at least during hoisting.
  • the change of the aerodynamic property may be introduced by changing the shape of the nacelle or by covering or shielding the nacelle by aerodynamic profiles forming part of the crane or other lifting equipment thereby reducing the influence of wind during lifting.
  • the method may include the step of reversing the temporary change of the aerodynamic property once the nacelle is attached to the tower.
  • reversing is herein meant that the initial shape is re-established, or that another shape is established.
  • the initial shape could be partly or fully re-established.
  • the nacelle may be transported with its initial aerodynamic property.
  • the initial aerodynamic property could particularly be obtained with a smaller volume of the nacelle, which thereby makes transport more efficient.
  • the change in aerodynamic property e.g. by changing the shape of the nacelle or by shielding the nacelle, is introduced to reduce the drag coefficient or the back-pressure. This may increase the volume of the nacelle, but it may also create a steadier lifting, and it may allow lifting at higher wind speed.
  • the method may include the step of transporting the nacelle in a state where it has an initial volume, and increasing the volume at the site of construction before lifting it by crane.
  • the change of the aerodynamic property may be introduced by changing the shape of the nacelle or by covering or shielding the nacelle by aerodynamic profiles, herein referred to as add-on profiles attached directly to an outer surface of the nacelle or attached to the crane, or forming part of the crane or other lifting equipment thereby reducing the influence of wind during lifting.
  • the aerodynamic add-on profiles could e.g. be attached to an outer surface of the nacelle and/or to a lifting yoke of the nacelle, and/or to lifting gear of the crane etc.
  • the add-on profile may e.g. be used as an interface between the crane and the nacelle for attaching the nacelle to the crane which is used for lifting the nacelle.
  • the add-on profiles may e.g. be connected to a lifting cable or a lifting hook or spreader of the crane.
  • the add-on profiles are attached both to an outer surface of the nacelle and to the lifting yokes or other lifting structures of the nacelle or of the crane used for lifting the nacelle.
  • the add-on profiles could be fixed ot the nacelle, and the nacelle and the add-on profiles could be indifidually attaced to a crane which is used for lifting the nacelle.
  • the add-on profiles and the crane could be detached from the nacelle and the add-on profiles may thereafter be lowered to the ground and used for lifting another nacelle.
  • the nacelle may e.g. be transported with an outer shieling layer, e.g. a housing of the kind generally known as the outer shell of a nacelle, and that outer shielding layer could be covered at least partly with the add-on profiles which are attached directly to the nacelle.
  • an outer shieling layer e.g. a housing of the kind generally known as the outer shell of a nacelle, and that outer shielding layer could be covered at least partly with the add-on profiles which are attached directly to the nacelle.
  • the aerodynamic add-on profiles can be rigid, dimensionally stable, elements made of aluminum, steel, composite of fibers and polyester etc., or, as an alternative to dimensionally stable elements, they may be made of flexible materials such as rubber etc. Preferably, such a flexible add-on profile may be inflatable.
  • the profiles can be triangular, semi-elliptical, or any other aerodynamic shape that can reduce the drag coefficient or back pressure of the nacelle.
  • the profiles can be attached to the nacelle by different fastening means such as screws, flexible straps, hooks, magnets, or adhesives etc. Particularly, the profiles may be attached by fastening means which can be released from inside the nacelle to thereby avoid work on the outside of the nacelle in high altitude.
  • the profiles can be in several separate pieces which can be mounted temporarily to the nacelle cover during lifting. Since the profiles are in separate pieces, it may be easier to transport them e.g. in a standard container, and it may be easier to handle them during use, e.g. easier to detach them from a nacelle and lower them to the ground, and it may be easier to ship them to another location for use in connection with erection of another wind turbine.
  • the step of introducing a temporary change to the shape of the nacelle may comprise the step of attaching the flexible material to an outer surface of the nacelle and inflating it e.g. before the lifting of the nacelle or once drag or back pressure becomes a problem.
  • the inflation is controlled by a level of back pressure or drag.
  • the method for making a wind turbine further comprises a step of lifting the nacelle assembly for attachment to a tower.
  • This step is typically performed by use of a crane, typically a mobile crane, or similar lifting equipment.
  • this step is performed at a wind speed lower than 15 meters per second and it should comply with the essential safety requirements.
  • Having a profile of a nacelle with reduced drag coefficient the maximum permissible wind speed during lifting by crane may be significantly increased.
  • the add-on profile(s) form lifting lugs for lifting the nacelle and thereby constitute not only a drag reducing structure but also a lifting aid for the crane operation.
  • the add-on profiles may thus form part of the nacelle and/or it may form part of the lifting lug or other lifting structure of the crane.
  • the method for making a wind turbine further comprises a step of re-establishing the initial shape of the nacelle.
  • the shape of the nacelle is thereby changed from an aerodynamic shape back to the initial shape. This step may be performed by removing add-on profiles which provide only a temporary change in the shape of the nacelle.
  • the step of re-establishing the initial shape of the nacelle may comprise a step of deflating the inflated profiles and optionally detaching the profiles from the nacelle. If the deflated profiles are not detached from the nacelle, the initial shape is only partly re-established.
  • the add-on profiles are arranged to shield side-surfaces of the nacelle, the side-surface being surfaces arranged on opposite sides of a drive train in the nacelle. In that way, the add on profiles may e.g. attached symmetrically, e.g. with respect to the centre of gravity of the nacelle, with respect to the location of the drive train e.g. symmetrically relative to a plane through the centre of the rotor shaft of the wind turbine, or symmetrically relative to the centre of gravity of the complete nacelle or relative to the centre of gravity of the drive train or just the drive shaft.
