Abstract:
The present invention is a device for controlling torque output of wind turbine blades, which can effectively keep the torque output of the blades of a wind turbine in constant and maintain the output stability of the wind turbine further. The present invention does not need any external power input and measurement signal generated from other devices and is a fully passive device which keeps the output of a wind turbine in constant. When the wind speed varies in the rated range, the present invention would adjust the pitch angle of the blades correspondingly and keep the output of a wind turbine in constant. When the wind speed is not in the rated range, the present invention would stop the rotation of the blades, so the output stability of the wind turbine can be kept, and the durability of the wind turbine can also be maintained.
