摘要： The invention describes a method for more efficient way of obtaining mechanical work and/or power generation from fluid flows with the oscillating motion of the blade and the counterweight in a direction that is perpendicular to the flow of fluid in conjunction with a smooth and periodic change of the angle of the blade to the flow of fluid over the sine wave which is characterized by being carried out by: rotating the surface of the blade to the direction of the fluid's flow and/or; changing the amplitude of the oscillation of the blade with respect to the fluid's flow rate and/or; changing the amplitude of the angle of the blade with respect to the fluid's flow rate; capturing mechanical work in the form of torque or tensile/compressive force to propel attached machinery or generate power from the arm of the counterweight. The invention further describes the apparatus to carry out this method.

摘要： System and method for controlling operation of a hydroelectric production system comprising electrical actuators operably connected at opposite positions of a gate operating ring for rotating the wicket gates to a desired position. The system receives a single control signal designed for a hydraulic system comprising hydraulic actuators operably connected to a single fluid reservoir and configured to work in tandem to produce simultaneous and opposite axial movements. The system comprises a control interface adapted to produce new control signals, each new signal being intended to a different electrical actuator to cause the electrical actuators to have axial movements which are identical in speed and in opposite directions to substantially imitate the exact movement of the hydraulic actuators onto the gate operating ring. The system is configured to introduce a dampening effect to reduce sudden acceleration and deceleration which is purposely used in hydraulic systems to overcome friction and static effects.
