Roller Compacted Concrete and Tunnel Boring Machines?Two Tools for Designers and Planners
Two tools that have come into use fairly recently are roller compacted concrete and tunnel boring machines. These new tools can significantly affect the ability to make new projects cost...
World's Largest SF6 Gas-Insulated Substation
The Itaipu hydroelectric powerplant is located on the Parana river which forms the border between Brazil and Paraguay. It will be the world's largest powerplant with an installed...
The Paerau Gorge Multipurpose Scheme
The Paerau Gorge Power Scheme is part of a multipurpose scheme supplying irrigation water and electricity to the Central Otago region of the South Island of New Zealand. This paper describes...
Risk Sharing in Project Development
This paper reviews some of the areas in which attention to detail can make the contractual relationship more positive and lead to a better project. Subjects covered include: selecting...
Checking Turbine Performance by Index Testing
This paper discusses an index testing procedure used by TVA for measuring performance levels of its hydroelectric units. It also describes a current program for retesting generating units...
Optimization of Low Head Hydro Equipment
In this paper, we will limit our purpose to the presentation of the different types of turbines that CE/Neyrpic proposes for low head power plants, for run of the river operations. We...
Conventional Machinery/Unconventional Applications
The U. S. Bureau of Reclamation has become increasingly involved in small-scale hydroelectric projects involving unconventional applications for conventional hydraulic machinery. One ongoing...
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,...
Specification Writing for Small Hydro-Generators
For small hydro projects, it is all too common for the spec writer to use a convenient off-shelf spec usually written for a much larger unit. Minor modifications (primarily ratings) are...
Conversion Experience at the Chief Joseph Dam Project
In August, 1983, Woodward Governor Company was awarded U. S. Army Corps of Engineers contract DACW67-83-C-0076 to convert ten existing Allis-Chalmers and six existing Woodward Governor...
Experiences During Overhaul of Hydroelectric Units
This paper describes some of the conditions found during major overhaul of main units at two hydroelectric power plants. Problems encountered and their solutions are described. The effects...
More Kilowatts with Less Investment
The paper discusses partial or complete modernization of hydraulic units and/or governing system as a means to increasing profitability. A combination of general and case history applications...
Practical Aspects of Repairing and Rewinding Hydro-Electric Generators
Often the general condition of the winding can be assessed and in some cases, corrective action can be taken to prolong the life of the winding. In other situations, the assessment may...
Performance Consideration for Selecting a Static Excitation System
Many hydropower plants today are being upgraded with new static exciter/regulator systems to replace the old existing rotary exciters. One type of system is the semi-inverting system where...
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...
Steel Poles?Past, Present and Future
When using steel pole structures, construction possibilities are limitless. Of all the options available, tubular steel structures provide the most versatility for transmission line construction....
Dynamics of Machine Foundation
The art of designing machine foundations, supporting vibratory load has changed from the approximate rule-of-thumb to the scientifically sound engineering procedure. However, the vast...
