    摘要: Disclosed is an energy converting apparatus for converting mechanical energy obtained by a fluid flow into electric energy. The energy converting apparatus comprises: a blade; a measuring device for measuring reaction of the blade when the fluid flow exerts an external force on the blade, and generating a measurement value corresponding to a measurement result; a memory for storing control values; a controller for reading a first control value among the control values from the memory in response to the measurement value output from the measuring device, and generating a control signal by using the first control value; and an actuator for changing a three-dimensional shape of the blade in response to the control signal output from the controller.

    摘要: A mud by-pass regulator apparatus for regulating the flow of drilling fluid through the turbine of a downhole power generator supply in a measurement while drilling system includes a valve (94), valve actuator (50), and a valve actuator control (60, 64, 72). Pressure differential across the turbine is sensed by a piston (60) located between high pressure (72) and low pressure (64) chambers increase in pressure differential moves valve actuator (50) against the bias of a spring (58) to move valve (94) away from turbine (88) and allow more fluid to by-pass the turbine. This ensures regulation of the drilling fluid flowing through the power supply so that its operation is maintained within required limits of the downhole portion of the measurement while drilling apparatus.

    摘要: A method and apparatus for controlling a variable-speed hydraulic power generation system using an induction generator (1) of wound-rotor type is disclosed, in which variation in frequency of the power system connected to the power generation system or power demand from the power system is detected and the detected value is applied to a control unit for controlling the guide vane (11) of a hydraulic machine (2) driving the generator, thereby dampening variation in frequency or power balance of the power system.

    摘要: The present invention relates to a movable and semi-submerged power generator using a waterwheel turbine, which can easily be moved to a location where a flow of a fluid occurs, prevents movement by current of water due to being a semi-submerged type, and efficiently produces energy by means of a flow rate control and cutoff of the fluid and expansibility of the turbine. The power generator comprises: an upper structure having first and second structures including first and second balancing tanks and first and second machine rooms; a lower structure disposed on the lower portion of the upper structure and including a fluid flowing hole, a first round, and a fluid guide hole through which the fluid can flow; a turbine rotated by the movement of the fluid; an energy generation means for producing electricity by the turbine; and a fixing means. Thus, the power generator is floatable and movable on water so as to be moved to and installed in various locations. The first and second balancing tanks are filled with the fluid such that the power generator can be semi-submerged, and the height of the turbine is disposed at a position so that a shaft can be placed above the water surface such that the turbine is smoothly rotated, while preventing shaking by waving of the fluid and turning of the power generator, thereby improving energy production efficiency. Also, the fluid under the water surface is guided in a direction capable of operating the turbine while maximally preventing disruption to the flow of the fluid moving to the turbine through the first round of the lower structure, thereby improving energy production efficiency.

    摘要: There is provided a submersible turbine assembly comprising: a frame sized and configured for supporting one or more flowing water driven turbines at a predetermined depth range below the surface of a water body having a bed, the frame including at least one fixed buoyancy component and at least one variable buoyancy component and optionally one or more hydrodynamic lift-generating surfaces, the one or more flowing water driven turbines being expected to produce a drag force which varies with water velocity, the assembly being arranged to be maintained in a predetermined position above the water body bed and submerged below the expected water body surface by at least two upstream taut mooring line runs and at least one downstream taut mooring line run, wherein the mooring line runs are arranged to be anchored to the water body bed at respective anchor points spaced apart from a point below the expected position of the assembly by at least the height of the assembly above the water bed, the frame having attachment points for said taut mooring line runs comprising upper and lower attachment points for spaced apart attachment of upper and lower or primary and secondary mooring lines or cables forming each mooring line run, the attachment points arranged to permit movement of at least some of the mooring lines relative to the frame during installation and having an arrangement for locking the mooring lines relative to the frame during use, the assembly being arranged so that in use in a water current having a nominal flow velocity of 3 metres per second both the upstream and downstream mooring line runs remain taut and wherein the net upward force resulting from the fixed and variable buoyancy and any hydrodynamic lift minus the weight of the assembly is at least 25% of the drag on the structure and thrust produced by the at least one turbine.

    摘要: A wind powered turbine has a conduit. A middle conduit portion is located between inlet and outlet conduit portions, having a main inlet and outlet of the conduit, respectively. A rotor having a shaft with blades extending therefrom is located in the middle conduit portion. The blades are located completely within the middle conduit portion. Preferably, a splitter is located in the inlet conduit portion to provide upper and lower sub-tunnels that both feed into the middle conduit portion. Upper and lower interior walls of the middle conduit portion have substantially circular plane shapes that are substantially centered at the rotational axis of the shaft. Upper and lower clearance gaps are located between the blades and the upper and lower interior walls, respectively. The main outlet is preferably higher than the main inlet. Preferably, a generator is located on each side of the conduit and rotatably coupled to the shaft.
