摘要： The object of the invention is to provide a control apparatus (C) of a horizontal axis wind turbine apparatus (WTG) that calculates the value en of a pitch angle command for each blade based on the rate of change (ΨD) of the azimuth angle (Ψ) of a nacelle (N) and the rotor azimuth angle (φ) of the blades (B1, B2 and B3), causes the rotor (R) to generate torque around the yaw axis by periodically controlling the angle change of the pitch angle of the blades (B1, B2, B3), and using that torque, controls the rate of change of the azimuth angle of the nacelle (N). The value of that angle change is calculated as a value that increases as the input value of the rate of change (ΨD) increases.

摘要： To provide a horizontal axis wind turbine capable of reducing flutter, and by extension, reducing the load on the wind turbine, without controlling the yaw, regardless of the direction of the wind relative to the nacelle. When the wind speed is above a specific value, the yaw angle of the nacelle is held constant, the blade pitch angle is controlled according to the yaw angle Y of the wind direction relative to the nacelle, and the rotor is allowed to rotate freely. Even when the yaw angle of the nacelle is held constant, allowing the rotor to rotate freely makes it possible to reduce the load by avoiding flutter.

摘要： The purpose of the invention is to protect, in a horizontal axis wind turbine with an exhaust aperture (4a) for exhausting air from within the nacelle (1), the exhaust aperture (4a) and the internal structures from storm winds through facing the exhaust aperture (4a) away from the storm wind, even when storm winds are received from all directions relative to the nacelle. A rotary duct (4) is attached to the nacelle (1) so as to be able to rotate freely in the yaw direction, and is rotated in the yaw direction in accordance with changes in the wind direction. The exhaust aperture (4a) is provided at a position that changes direction depending on the rotation of the rotary duct (4) in the yaw direction. By rotating the rotary duct (4) in the yaw direction so that the exhaust aperture (4a) will face the downwind side in accordance with changes in the wind direction, the exhaust aperture (4a) can be faced away from storm winds, even when storm winds are received from all directions in relation to the nacelle (1).
