    • PROBLEM TO BE SOLVED: To provide an operation device for a windmill and its operation method for preventing the breakage of a blade by avoiding an excessive and irregular load such as a load in the oblique direction to work on a blade even if a power failure occurs when a strong wind acts on it. SOLUTION: This operation device for the windmill is provided with a supporting column 106 erected on an installation face on the ground or on a ship, a windmill body 100A provided with a nacelle 102 supported so as to turn freely in the horizontal direction of turn, a rotor 105 provided with a plurality of blades and rotated by wind power, and a power generator stored in the nacelle 102 and connected with the rotor 105, a turn driving mechanism 4 for turning the windmill body 100A, and a brake device for suppressing the turn of the windmill body. In this operation method for the windmill for rotating the rotor connected with the power generator by wind power received by the blade 101, the windmill body is turned at least until the rotor comes on a down wind (leeward) side, and then the turn of the windmill body follows the direction of wind naturally.

    • PROBLEM TO BE SOLVED: To provide a lightning protection device for a wind turbine blade and an assembly method for the lightning protection device, in which a receptor installed to a blade tip part, where its blade profile is small, can be easily assembled with simple structure, and which can effectively respond to pressure increase generated inside the blade in lightning strike on the blade. SOLUTION: In the lightning protection device for a wind turbine blade, a receptor for lightning strike is installed on a surface of the blade, a lightning current from the receptor is grounded through connected equipment such as a conductor or a bypass blush passing through the inside of the blade and a wind turbine main body part. The lightning protection device has a receptor assembly constituted in such a way that a base plate made of electric conductor and connected with the conductor is laid in the blade and the receptor is fixed to and supported by the base plate so that the receptor faces the surface of the blade.
