摘要： In an oscillating water column (OWC) assembly power may be generated based on a power reference that is derived from an estimate of the available mechanical power in the air turbine 2 or a measured pressure drop across the turbine. The power reference is used to derive a power control torque reference within a power controller 14. A speed controller 16 uses a comparison of a measured speed of the generator 8 and a maximum speed limit to derive a speed control torque reference. A selector function 22 selects whichever of the power control and speed control torque references is the maximum at any time instant. The selected torque reference is input to an anti stall torque function 24 where it is selectively modified by applying a speed dependent gain that decreases with decreasing turbine speed, preferably so that the main torque reference is zero for a minimum speed limit.

摘要： A system for harvesting, storing, and generating energy, that includes floating structure supporting machinery to extract energy from wind, waves, surface generators, or currents. At least one energy storage and power generating unit is anchored to the seafloor and adapted to tether the floating structure to the unit. The unit includes an internal chamber into which water flows through a hydroelectric turbine to generate electrical energy. A pump is provided, powered by energy from the floating structure machinery, to evacuate water from the unit and a control system directs power from the machinery to pump water out of the unit during periods of excess energy extraction by the machinery and to allow water to flow into the chamber through the hydroelectric turbine to generate electrical energy during periods of lower energy extraction by the machinery. The same internal chamber design can be utilized to store hydrocarbons in the vicinity of undersea wellheads during “shut-in” procedures when the wellhead would otherwise be secured.

摘要： An energy generating device may include a first body portion with at least one first force input structure coupled to the first body portion and configured to receive an external force. The energy generating device also may include a second body portion, the second body portion rotatable relative to the first body portion. Further, the energy generating device may include an electrical generator configured to use the relative motion between the first body portion and the second body portion to generate electricity. The first body portion and the second body portion are configured to descend through a medium at least partially under the force of gravity or ascend through the medium at least partially by buoyant forces in such a way that the medium causes a force on the at least one first force input structure by impinging on the at least one force input structure causing relative rotation between the first body portion and the second body portion. An energy generating device may include at least one first body portion, at least one second body portion, at least one torque generator configured to cause relative rotation between the first body portion and the second body portion, and at least one electrical generator configured to use the relative motion between the first body portion and the second body portion to generate electricity, wherein the first body portion and the second body portion are configured to descend through a medium at least partially under the force of gravity or ascend through the medium at least partially by buoyant forces in such a way that the torque generator causes relative rotation between the first body portion and the second body portion.

摘要： A power generating device utilizing oscillating water for converting into wave power (1) includes: a power generating tank (10) formed with a first chamber (11), a second chamber (12) and a communicating hole (13); a quantitative liquid (20) filled in the first chamber (11) and the second chamber (12); a resonating member (30), having one end communicated with the first chamber (11) and the other end disposed in a wave (2); a quantitative gas (40) filled between the first chamber (11) and the resonating member (30); and a driving member (50, 50′, 50″) pushed by the quantitative liquid (20). Accordingly, during the reciprocal movement of the wave (2), the quantitative gas (40) is pushed and squeezed thereby enabling the quantitative liquid (20) to push the driving member (50, 50′, 50″) so as to generate power.

摘要： Several embodiments of a device for economically harvesting wave energy are disclosed. A sealed vessel for air storage, the spar buoy, is mostly submerged under water is also used as an inertial body that surface floats move relative to. The spar buoy may take many geometrical forms, but all have a stem that is above the water surface. Piston pumps are placed at the top of the stem. The pump has a gearing reduction to optimize the rotational motion of the pump drive shaft. Small angular motion at the drive shaft results in multiple cycles of linear reciprocal motion of the piston. Various mechanisms could convert the relative motion between the floats and the spar buoy to a rotational motion of the shaft. The compressed air generated by the pump is stored in the spar buoy and regenerated as electrical energy by expanding the compressed air in a turbine.
