Embodiment Construction
[0018] The blade feathering method of the wind turbine of the present invention is to select at least two shutdown feathering modes according to the average wind speed during shutdown feathering, utilize the difference in pitch rate between at least two feathering modes, and the average wind speed during shutdown feathering When the wind speed is low, the corresponding feathering mode has a higher pitch rate, and when the average wind speed is higher, the corresponding feathering mode has a lower pitch rate. This feathering method can effectively reduce the load during shutdown and ensure wind power The purpose of a smooth shutdown of the unit.
[0019] The principle that the corresponding pitch rate when the average wind speed is low is higher than that when the average wind speed is high is: when the wind turbine is at different pitch angles, the aerodynamic torque and the wind wheel The thrust loss is different. When the fan unit is at a small pitch angle, the aerodynamic t...
