摘要： The present invention relates to an air turbine capable of without change in its rotational velocity direction, efficiently absorbing the energy associated with a pressure difference between two spaces (A) and (B) of successively changing sign, as in the case of sea wave energy systems. The turbine comprises two sets of blades (I) and (II), each of which is similar to the blade system of a conventional turbine of radial-, mixed- or axial-flow type. The turbine also comprises a system of ducts that connect spaces (A) and (B) through any of the two blade sets (I) and (II). The turbine may be equipped with a fast-acting valve that stops the flow through one or both blade sets (I) and (II).

摘要： An oscillating water column (OWC) turbine and method of extracting energy therefrom is provided. The OWC turbine includes a shaft (101) rotatable about a central axis (103), and first and second ports (112, 114) disposed around the central axis. A flow passage (104) extends radially-inward from the ports and extends axially therebetween. Rotor blades (120) are coupled to the shaft, intersect the flow passage, and are offset from the central axis by a first distance. First guide vanes (116) intersect the flow passage and are disposed proximal the first port. The first guide vanes (116) include first and second stators (116a, b), the first stators (116a) being positioned between the first port (112) and the second stators (116b). Second guide vanes (118) intersect the flow passage and are disposed proximal the second port. The first and second guide vanes are offset from the central axis by a second distance that is greater than the first distance.

摘要： An energy storage and regeneration system that converts irregular, non-constant, and variable input power to regular, constant, and controlled output power using hydraulics whereby the irregular input power is used to pump hydraulic fluid into an accumulator array where it is stored pressurized. Energy is released in a controlled fashion using a hydraulic motor operated by the pressurized hydraulic fluid from the accumulator array, in accordance with the specified power demand. One or more power units may be deployed depending on the amount of energy required at the output. Each power unit includes a hydraulic motor and associated floating accumulator whose internal pressure is controlled to maintain a substantially constant pressure differential across its associated motor. The system can be integrated into various energy system sources including renewable energy such as wind, PV or thermal solar, wave, tidal, etc.

摘要： An axial-flow turbine assembly that includes one or more features for enhancing the efficiency of the turbine's operation. In one embodiment, the turbine assembly includes a turbine rotor having blades that adjust their pitch angle in direct response to working fluid pressure on the blades themselves or other part(s) of the rotor. In other embodiments, the turbine assembly is deployable in an application, such as an oscillating water column system, in which the flow of working fluid varies over time, for example, as pressure driving the flow changes. In a first of these embodiments, the turbine assembly includes a valve that allows the pressure to build so that the flow is optimized for the turbine's operating parameters. In a second of these embodiments, one or more variable-admission nozzle and shutter assemblies are provided to control the flow through the turbine to optimize the flow relative to the turbine's operating parameters.

The set of electro-hydro-dynamic actuators are disposed proximate to the power modules to, responsive to control of the digital programmable governor and in association with a thermal cycle of adding heat to and removing heat from the working fluid, provide influence to drive reciprocal flows of the working fluid through the power modules. The bi-directional turbines are disposed to receive the reciprocal flows and perform a kinematically independent conversion of the operating medium reciprocal flows to rotary motion power output.

摘要： To increase in particular the level of efficiency in the conversion of sea wave energy into electrical energy there is proposed a wave power generating installation having a chamber for the positive guidance of an oscillating water column, wherein the chamber which is closed in itself below the surface of the water has an opening through which water flows into the chamber and then out again, and a means for taking mechanical energy from the oscillating water column and for converting the mechanical energy into electrical energy. The generating installation according to the invention is distinguished in that the means includes a float body device carried by the water column and a linear generator having a stator and an actuator, wherein the float body device is mechanically operatively connected to the actuator of the linear generator and the actuator for generating electrical energy is reciprocatingly movable by the movement of the float body device relative to the stator of the linear generator.
