6 results about "Small hydro" patented technology

Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. The definition of a "small hydro" project varies based on different consideration of what should constitute bottom and top limits from country to country, but most common range, although not binding, in capacity of "small hydro" extend between 1 to 15 megawatts (MW), and can be further subdivide by scale into "mini" (<1MW), "micro" (<100kW), "pico" (<10kW). In contrast many hydroelectric projects are of enormous size, such as the generating plant at the Three Gorges Dam at 22,500 megawatts or the vast multiple projects of the Tennessee Valley Authority. In India, hydro projects up to 25 MW station capacities have been categorized as Small Hydro Power (SHP) projects.

Small hydroelectric power generation equipment

To provide a small hydroelectric power generating device capable of stably generating electricity by utilizing a small water flow. [Solution] The device comprises a first cylindrical portion 10 and a second cylindrical portion 20 arranged in parallel, a water branching portion 30 that alternately supplies water from a water source to the first cylindrical portion 10 and the second cylindrical portion 20, a moving member 40 that is within the first cylindrical portion 10 and the second cylindrical portion 20 and is positioned between the water supplied to the first cylindrical portion 10 and the second cylindrical portion 20 from the water branching portion 30 and the air present within the first cylindrical portion 10 and the second cylindrical portion, an air movement passage 50 that, when the moving member 40 within the first cylindrical portion 10 descends, causes the air below the moving member to move toward the second cylindrical portion 20, and when the moving member 40 within the second cylindrical portion 20 descends, causes the air below the moving member to move toward the first cylindrical portion 10, and a power generation mechanism that generates power using the movement of air moving through the air movement passage.

Micro-hydro power generation system using water flow

ActiveKR102992849B1Water turbineHigh energy
The present invention relates to a small hydroelectric power generation system utilizing water flow, wherein the system comprises: a pair of helical turbines (100) having a plurality of helical rotating blades that rotate in opposite directions to enable stable rotation even with resistance and lift caused by water currents and turbulent currents; a support frame (200) that stably supports the pair of helical turbines (100) underwater and can be fixedly mounted with one or more of them; a pair of guides (300) fixedly mounted on the support frame (200) that filter out the attachment of sludge flowing along currents or water flow, divide the fluid flow to allow it to flow into and out of the pair of helical turbines (100), and simultaneously increase rotational inertia to help the stable rotation of the turbines; and a gearbox (400) that matches the high torque of the pair of helical turbines (100) with the high rotational speed of the generator. By implementing a small hydroelectric power generation system using water flow characterized by including a power generation module (500) having a control means (510) that produces and controls alternating current (AC) electricity by the continuous and stable rotation of the above pair of helical turbines (100); and an air-floating body (600) that floats the power generation system to the upper part of the floating body when installing the power generation system underwater or during repair and maintenance, it has the effect of high energy conversion efficiency utilizing both drag force from the water current and lift force from the vortex, and stable power generation and repair and maintenance are possible even in turbulent and rapid currents.
