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 one auxiliary unit. To increase flexibility and improve assembly and maintenance procedures of the wind turbine, the auxiliary unit comprises at least two sub units each accommodating at least one wind turbine component, e.g. a converter or a transformer. The sub units are attached individually to the main unit or they are joined and attached as one component to the main unit.
Claims25
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 a wind turbine tower and housing the rotor-supporting assembly, and
- at least one auxiliary unit,
- wherein the main unit and the at least one auxiliary unit are separate units assembled at a first interface, and
- wherein the at least one auxiliary unit comprises at least two sub units individually attached to the main unit at the first interface.
A method of making a nacelle for a wind turbine, the nacelle comprising a main unit and at least one auxiliary unit, the at least one auxiliary unit including at least two sub units, the method comprising:
- receiving at least two wind turbine components each being encapsulated in a container forming a respective one of the at least two sub units, and
- attaching the at least two sub units with the encapsulated components therein to the main unit of the nacelle at a first interface,
- wherein attaching the at least two sub units includes individually attaching each of the at least two sub units to the main unit at the first interface.
