A reinforcement object is reinforced without being carried out from a wind turbine power generation facility. A method of remodeling a wind turbine power generation facility includes: a carry-in step of carrying a reinforcement member into a hub through an opening portion which has a smaller dimension than a reinforcement object inside the wind turbine power generation facility and which brings into communication inside of the hub and outside of a front side of the wind turbine power generation facility, the reinforcement member having a smaller dimension than the opening portion; and a reinforcement step of processing the reinforcement object inside the hub, and reinforcing the reinforcement object by using the reinforcement member carried into the hub.

A rotor turning device for a wind turbine generator which can be used without having to modify the existing wind turbine generator. A rotor turning device includes, on the inner periphery, a first member acting as a fixing member for fixing to a coupling hub, and on the outer periphery, a second member acting as an operating member to which operational force for rotating a rotation axis of the wind turbine generator. A pair of the first members embracingly fixes to the coupling hub of a coupling, while the second member attaches to the pair of first members to form a handle-like shape.
