Wind turbine nacelle with suspended power conversion assembly
A recently granted patent (Publication Number: US11971016B2) discloses a wind turbine nacelle design that aims to improve efficiency and ease of maintenance. The nacelle is configured to be mounted on a wind turbine tower and houses a rotor-supporting assembly along with a power conversion assembly. The innovation lies in the separation of the main unit, housing the rotor-supporting assembly, and at least one auxiliary unit housing an operative component of the power conversion assembly. These units are connected by a unit fixation structure at an interface, with the operative component suspended directly on the main unit. This arrangement allows for a more streamlined and efficient design, with the main unit and auxiliary unit positioned side by side in a direction transverse to the rotor's rotational axis.
Furthermore, the patent details a method of assembling and servicing the wind turbine with this nacelle design. The assembly process involves attaching the auxiliary unit to the main unit and directly attaching the operative component to the main frame. During servicing, the operative unit can be detached from the main unit while contained in the auxiliary unit, simplifying maintenance procedures. The design also includes features such as suspension structures and wall openings to facilitate the movement and connection of components. Overall, this patented nacelle design offers a novel approach to wind turbine construction, focusing on efficiency, ease of assembly, and maintenance, which are crucial factors in the renewable energy industry's drive for sustainable solutions.
