A wind turbine power generating apparatus includes: a nacelle supported on a tower; a rotor including a blade for receiving wind power, the rotor being configured to rotate upon receiving wind at the blade; a rotor shaft coupled to the rotor and supported rotatably on the nacelle; a generator which generates electric power from rotational force of the rotor shaft; and at least two rigidity-enhancing parts disposed on an inner circumferential surface or an outer circumferential surface of at least one of the rotor shaft or the tower, at an interval which is set so as to correspond to a frequency of oscillation caused during operation of the generator, or oscillation caused during operation of a drivetrain for transmitting the rotational force of the rotor shaft to the generator in a case where the drivetrain is provided, arranged in a propagating direction of the oscillation. |
