Control mechanism for a windmill
Patent
·
OSTI ID:6357469
A method and apparatus are provided for controlling the maximum power of a hydraulic windmill which is achieved by utilizing the overpressure created in a closed loop hydraulic energy conversion system to rotate the tail of the windmill away from its operating plane to reduce the power transmitted from the wind to the blades of the windmill. A mechanical braking mechanism may be applied to the windmill blade driven rotatable shaft upon a sensed overpressure in the hydraulic fluid which acts through a differential between the hydraulic overpressure and a preset pressure to effect closure of the brake.
