Valuation of System Hydro Additions
The purpose of this paper is to examine the major factors and steps which affect the valuation process of adding hydro power plants to an integrated hydro-thermal generation system. Results...

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...

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...

Dam Safety Relating to Merwin and Yale Hydroelectric Projects
This paper describes the safety investigations performed to evaluate the dams, associated with the Merwin and Yale Hydroelectric Projects, for the effects of severe floods and earthquakes....

Application of Computer Aided Design and Analysis Tools for Upgrading Existing Power Plant Equipment
This paper presents examples where state-of-the-art computer aided design and analysis techniques have been applied to upgrade hydraulic performance and structural reliability of existing...

Synopsis: Ozark-Webbers Falls Turbine Repairs
The Ozark and Webbers Falls powerhouses were designed and constructed under the supervision of the U. S. Army Corps of Engineers and are located on the McClellan-Kerr Arkansas River Navigation...

Application of an Integrated Numerical System for the Modernization of Hydro Turbines
The modules of an integrated numerical system for the new design and replacement of hydro power plant components are described and some examples of application are shown. The main modules...

Real Time Information Systems for Improved Port Operations
The technology to make appropriate measurements and to forecast conditions for short intervals is available today. Simple collection, analysis and dissemination systems are within the...

Interactive Simulation of Hydropower Systems
This paper describes a new educational technology that has proven extremely effective in introducing both technical and lay persons to the operational principles, management alternatives,...

Hydroelectric Project Design Using Microcomputers
The main issue in the first stage of a hydroelectric project is to assess the influence of hydrologic parameters on design and optimum sizing of the installation and on future energy production....

Hydro Systems Evaluation on Personal Computers
The programs for selecting the equipment and determining the average annual energy have been separated from the detailed financial analysis. The BASIC language was selected for the first...

Microcomputers as Productivity Aids for Small-Scale Hydroelectric Projects
Off-the-shelf software that has been used to improve productivity includes Computer-Aided-Design-and-Drafting (CADD) systems, spreadsheets, project managers, word processors, and communications...

Computer Modeling and Applications
A series of programs is available to evaluate the hydrology, compute the capacity to generate energy, establish unit costs, analyze penstock surge pressures, and simulate ramping rates....

Three-Dimensional Plotting in Dam Potentials
Hydroelectric development is important to many basins in the western United States. Topographical studies are normally used to arrive at sites to be chosen for further investigation of...
