This paper presents a discussion of the relative merits of each alternative, with emphasis placed on experience gained from projects recently completed. The discussion considers such factors...
Hydraulic Transients?Helms Pumped Storage Project
Pacific Gas and Electric Company's Helms Pumped Storage project is a large underground hydroelectric development which went into commercial operation in June 1984. Because...
The Pacific Northwest Hydropower Data Base Study
The Hydropower Data Base is presently a functional tool for evaluating hydropower in the Northwest. It is a complete system which has been implemented using a variety of crosschecks and...
The Corps of Engineers' New Hydropower Manual
The Corps of Engineers has recently completed a new Engineering Manual (EM), which outlines procedures used for the evaluation of hydropower projects. It will serve as the basic Corps...
Friant Power Project: Design and Construction?Non-Federal Power at a Reclamation Facility
Friant Dam, Millerton Reservoir, provides the principal water supply for the Friant Division Central Valley Project of the U. S. Bureau of Reclamation (Bureau). The dam is a 319-foot high...
Economic Analysis of Hydroelectric Projects
This paper deals with specifics and refinements that develop 'rules of thumb' for analysis of hydro projects. The authors' experience is on sites...
Economic Evaluation of Alternative Electric Power Developments
A hydroelectric-dominated power system and a thermal-dominated system represent different ways of meeting total electric demand, but with materially different cash flow patterns. This...
Laser-2-Focus Flow Measurements in the Runner of a Bulb Turbine and Comparison with Calculation
Flow measurements are presented, which were carried out near and inside the 4-blade runner of an axial model bulb turbine of double adjustable type. These measurements were performed by...
The Design, Analysis and Manufacturing of Pickwick Landing Replacement Runners
This paper presents new computer automated techniques for the design, analysis and manufacture of Kaplan turbine blades. The inlet flow field was determined using the finite element program...
Design and Manufacture of Turbine Runner Blades Using CAD/CAM-Technology
Interactive blade design, fluid flow analysis, stress analysis and NC-matching of both model and prototype blades are working from a common data base and are demonstrated in this paper....
Advance Prediction of Flow-Induced Variations
Frequency analysis of hydraulic vibrations has been applied using a transfer matrix and impedance method. The computer program is given for the self-excited and forced vibrations, together...
Hoover Dam Plus Fifty Years Equals El Cajon Dam
The completion of El Cajon arch dam on the fiftieth anniversary of the completion of Hoover Dam has given the opportunity to compare design and construction of two concrete arch dams constructed...
Evaluation of Liquefaction Potential of Anderson Ranch Dam
This paper contains a description of a liquefaction evaluation of the alluvial foundation soils at Anderson Ranch Dam, which was performed as part of the USBR's program of...
Control System Design Considerations for Small Hydro Projects
This paper deals with the philosophy that must be embraced when specifying a fast track small hydro project. The major areas discussed are: the role of control systems in the context of...
Electrical Design of Small Hydro Plants
Major aspects of electrical design criteria for small hydro power plants used in co-generation schemes are: turbine control, generator and excitation equipment selection, protection relaying,...
Dynamic Analysis of Existing Tarbela Intake Towers
According to general practice at the time of the design, the pseudostatic method of applying earthquake loading was used. The basic acceleration was 0. 1g. A post-construction seismological...
