In a main bearing replacement method for a wind turbine power generation facility including a nacelle, a rotor head rotatably supported by the nacelle, a drive shaft to which rotation of the rotor head is transmitted, a main bearing disposed between the rotor head and the nacelle, and a coupling connecting the rotor head and the drive shaft on a radially inner side of the main bearing, the wind turbine power generation facility includes a main bearing sleeve fitted and fixed to an inner ring of the main bearing and mounted with the rotor head, and the main bearing is replaced at least while the main bearing sleeve is fitted and fixed to the inner ring of the main bearing.

Main bearing replacement method for wind turbine power generation facility

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.

Method of remodeling wind turbine power generation facility

In the aspect of the present invention, an installing a wind turbine is achieved by forming a blade assembly in which a plurality of blades are attached to a rotor head, by attaching a suspension structure to the rotor head, by lifting the blade assembly through the suspension structure by a first crane, and by installing the blade assembly to a nacelle of a wind turbine tower.
