Abstract
A wind turbine nacelle configured for mounting on a wind turbine tower and for supporting a rotor-supporting assembly, the nacelle comprising a main unit, and at least two auxiliary units. To increase flexibility and improve assembly and maintenance procedures of the wind turbine, the auxiliary unit comprises at least two auxiliary units each accommodating at least one wind turbine component, e.g. a converter or a transformer. The auxiliary units are attached individually to the same wall of the main unit, e.g. to a side wall or a rear wall.
Claims22
A wind turbine nacelle configured for mounting on a wind turbine tower and housing a rotor-supporting assembly defining a rotational axis, the nacelle comprising:
- a main unit arranged to be connected to the wind turbine tower and housing the rotor-supporting assembly, the main unit comprising:
- a first side wall and a second side wall on opposite sides of the rotational axis, and
- a rear wall extending transverse to the rotational axis between the side walls, and
- a plurality of auxiliary units, at least some of the plurality of auxiliary units being arranged along the rear wall and at least one of the first side wall and the second side wall of the main unit,
- wherein:
- the main unit and a first of the plurality of auxiliary units are assembled at a first interface,
- the main unit and a second of the plurality of auxiliary units are assembled at a second interface, and
- both the first and the second interfaces are in a first wall being one of the first side wall, the second side wall, or the rear wall.
A method of making a nacelle for a wind turbine, the method comprising:
- receiving a plurality of wind turbine components being encapsulated in a plurality of auxiliary units, and
- attaching the plurality of auxiliary units with the encapsulated components to a main unit of the nacelle,
- wherein at least some of the plurality of auxiliary units are arranged along a rear wall and at least one of a first side wall and a second side wall of the main unit.
