Economical Computer Controls for Low Head Hydro
Small power systems based on renewable energy sources such as low head water falls, wind, solar and ocean tides all suffer from stochastic changes in input power. Economically viable,...
Small Scale and Low Head Hydro Development in Canada: An Overview of Federal Activities and Policy
Through research and development, new small turbines have been tested and a Darrieus type vertical axis hydraulic turbine (VAHT) has been developed and field tested. Manuals for hydrologic...
Small Hydropower Potential in Missouri
The hydropower potential of small head plants on the Gasconade River was investigated. Since, it is felt that small head plants will have less environmental impact, thus it will be more...
Selection of Small Hydro Project Sites
In the course of studying nearly forty areas in Peru to identify possible sites for small hydro development and in order to select the best in each area for detailed design, the Authors...
Criteria for Selecting Turbine-Pumps Used in Mini-Hydro Power Units
The present paper is aimed at studying turbine-pump units operating at low heads. The proposed methodology is based on the global matching of the turbine and the pump so that both will...
A Marine Thruster in Small Scale Hydropower
A 70 kW hydroelectric plant utilizing a marine thruster as a turbine was commissioned in May, 1985. The thruster, the construction management, the site conditions and the testing program...
Development of Two Plants on California Canals
The projects utilize the head drop between canals on the system of the Central California Irrigation District (CCID. ) The projects utilize the elevation difference between the District's...
Low Head Hydroelectric Development on Madera Canal
The Madera-Chowchilla Power Authority with cooperation from the U. S. Bureau of Reclamation has been successful in the development of four hydroelectric plants at five head drops on the...
Two New Machines for Ultra Low-Head Hydropower
