Pit-Type Bulb Turbines?An Economic Solution for Low-Head Applications
For improving the profitability of extremely low head power plants the pit-type bulb turbine conception was developed, based on extensive model tests and on the operating experience with...
Pit Turbine Technology for Low Head Hydro Projects
Manufacturers of hydro generating equipment have developed designs that are adaptable to existing dams and suitable for upgrading and redevelopment of existing hydro plants. The pit turbine...
Optimisation of Bulb and Kaplan Turbine Runners
The paper presents a brief survey of the theoretical method used so far at Turboinstitut Ljubljana for axial runner design and analysis. Theoretically optimised runner is later experimentally...
Calculation of Blade Trunnion Reactions in Kaplan Turbines
A computer program is presented to calculate the blade trunnion reactions in Kaplan turbines. The program calculates the trunnion reactions for operation of the turbine at steady state...
Hydro Research and Plant Renewal
Obtaining extra energy or output from existing plants is the current topic when the question of refurbishing older turbine installation arises or when plant operating conditions can be...
Bureau of Reclamation Uprating Program
The Bureau of Reclamation is an agency of the Department of the Interior and was established in 1902 to oversee the development and conservation of the Nation's water resources...
Rehabilitation of a High Specific Speed Francis Turbine
An upgrade of two (2) 4. 06 meter diameter high specific speed Francis turbines is now in progress. These machines were originally installed by Allis-Chalmers in the 1920's...
Pontook Hydroelectric Project?A Turnkey Case Study
This paper is presented in two parts. The first, presented by B. H. Adams, gives a general overview of the Pontook Project including major physical features and the financed turnkey approach...
Potential for Upgrading the Robert Moses Niagara Power Plant
This paper summarizes the feasibility of increasing the generating capacity of the Robert Moses Niagara Power Plant by replacing the turbine runners, upgrading the generators, and replacing...
The Design of the Nanpil River Hydropower Project
In 1980, the State of Pohnpei (then spelled Ponape) asked the Pacific Ocean Division of the U. S. Army Corps of Engineers to investigate the feasibility of constructing a hydroelectric...
