Design of the Tunnel System for the Terror Lake Hydroelectric Project
The Terror Lake Hydroelectric Project, Kodiak, Alaska, contains a 5-mile-long (8. 1 Km) power tunnel with supplementary stream diversions entering it by two shafts along its alignment....
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...
Sherman Island Hydro Cofferdam
The design and construction of an eight hundred foot long by sixty-five foot high cofferdam is discussed. The cofferdam was located to permit major renovation of the existing downstream...
Arch Dams for Small Hydroelectric Sites
Approximate formulas are developed for the design of small arch dams. These designs, although conservative, frequently allow for economies over other dam types. Considered are: an approximate...
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...
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...
Nanpil River Hydropower Project Pohnpei, Federated States of Micronesia
The Nanpil River Hydropower Project is a 1600 KW run-of-the-river hydropower project located on the tropical island of Pohnpei, Federated States of Micronesia. The hydropower project will...
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...
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 Rehabilitation at Selected TVA Hydroelectric Projects
In response to President Carter's 1976 memorandum to all Federal agencies with responsibility for dams to develop and implement formal guidelines for dam safety, TVA restructured...
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....
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...
Carmen-Smith Uprate & Modernization
The Carmen-Smith Powerhouse is located on the upper McKenzie River, 75 miles northeast of Eugene, Oregon. Carmen's two nearly identical 42. 1 MVA vertical hydroelectric turbine...
Modernization of Existing Hydroelectric Power Stations in Conjunction with Conversion to Automatic Operation
The easiest and, in the long run, the least expensive method in most cases is the installation of an electronic turbine governor that is not only easy to incorporate in the power station...
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...
Analysis of Expanding the Wolf Creek Powerplant
The Nashville District, Corps of Engineers, is examining the feasibility of expanding the Wolf Creek powerplant to increase its peaking capability. The economic analysis of peaking expansions...
Application of Computer Aided Design and Analysis Tools for Upgrading Existing Power Plant Equipment
