A structure for a nacelle cover connection portion of a wind turbine generator includes a lengthy first angled member fixed to an inside surface of a nacelle cover and forming an upper end portion of a side wall panel; and a lengthy second angled member fixed to the inside surface and forming a lower end portion of a roof panel. An upper surface of the first angled member and a lower surface of the second angled member are aligned with and fixed to each other. A covering portion covering the upper end portion from the outside of a nacelle is provided at a predetermined interval from the same and integral with the lower end portion so as to protrude to the outside of the nacelle cover farther than the lower end portion. A packing is interposed between the upper and lower surfaces.

The present invention provides a composite material panel structure and a manufacturing method thereof with which an anti-lightning function can be realized without adding a separate anti-lightning structure to the composite material panel structure. In a composite material panel structure formed from a composite material panel containing reinforcing fibers, the composite material panel includes: a fiber-reinforced base material impregnated with a matrix resin; a conductive mesh sheet disposed on one surface side of the fiber-reinforced base material; and a bag film disposed on the one surface side of the fiber-reinforced base material so as to sandwich the conductive mesh sheet. The conductive mesh sheets of a plurality of the composite material panels are electrically connected to each other.

Composite material panel structure and manufacturing method

To provide a nacelle roof structure of a wind turbine generator, where the nacelle roof structure is capable of reducing stress concentration on joints of a roofing member divided into multiple parts to accommodate growing size of a nacelle as well as improving transport efficiency of the roofing member. A nacelle roof structure of a wind turbine generator, with a top face of a nacelle being covered with a plate-type roofing member (), in which the roofing member () has a joining structural portion () in which roof shingles () that divide the roofing member into a plurality of parts in a main-shaft direction are combined and plate couplings provided at opposite ends in the main-shaft direction are fastened together by being laid one on top of another; and two or more of the roof shingles () are equal in cut length in the main-shaft direction.
