Simplified Model for Micro-Hydro Feasibility
A computer model was developed for evaluating the preliminary hydraulic and economic feasibility of potential micro-hydro development sites. Among the main objectives of the model are...
Computer Modeling for a Power Intake
This paper describes the application of an existing computer model to respond to environmental requirements for a small scale hydroelectric power plant being developed by Allegheny Electric...
Simulation of River Ice Processes on Alaska's Susitna River
A numerical river ice model is applied to an 85-mile reach of Alaska's Susitna River immediately downstream of the proposed Susitna Hydroelectric Project. The model is designed...
Riverbank Stability and Monitoring at Grand Coulee Dam
The capability for hydroelectric power generation at Grand Coulee Dam was substantially increased following construction of the third powerplant in the mid 1970s. Increased river fluctuations...
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...
U.S./PRC Cooperation on the Three Gorge Project
The Three Gorge Project is the keystone project in developing and using the Yangtze River. It is located on the main stem of the Yangtze River, about 40 km upstream from the Gezhouba Project...
New Runners for Aswan High Dam Power Station
Replacing turbine runners at Egypt's Aswan High Dam Power Station is a major project because of the size, quantity and importance of these turbines to the Egyptian economy....
The Impact of Proposed Federal Income Tax Changes on the Financing of Hydroelectric Projects
The paper presents an overview of the specific proposed changes that would have the greatest direct impact on the hydroelectric power industry. Next, it presents the major conclusions...
LRFD Format for Transmission Structures
The structural design of high voltage electric transmission lines in the US is usually governed by the National Electrical Safety Code (NESC). A simple reliability-based Load and Resistance...
Wind Loads on Electrical Transmission Structures
Guidelines for structural loads on electrical transmission structures were prepared by the American Society of Civil Engineers' Committee on Electrical Transmission Structures....
A Field Study of Wind-Induced Conductor Loads
A 161 kV steel pole line in Omaha, Nebraska, is instrumented to provide conductor load field data due to climatic events. Various transducers and monitoring equipment used for data acquisition...
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....
Lattice Tower Design Using Cold-Formed Shapes
The use of cold-formed shapes in lieu of hot-rolled angles may lead to major changes in the design of lattice transmission towers. The design procedure of the new shapes is more creative,...
Innovations in Prestressed Concrete Structures
Prestressed concrete poles are probably the best choice for most transmission line structures. They have many advantages over structures made from other materials for both engineering...
Cold-Formed Angles for Transmission Towers
Cold-formed members enable the engineer to design transmission towers that may be more cost-effective than those built with hot-rolled angles. Members can be designed to closely fit the...
Design and Test of Cold Formed Steel Members
Latticed systems represent the most spread and low-cost solution for electrical trasmission towers, when ground conditions do not affect the design choice. Steel angles have been used...
Bolted Connections for Steel Towers
Laced electrical transmission towers require on-site assembly. Consequently, the number of bolts and pieces are important considerations in the total cost of the structures. ASTM A394(1)...
IEEE/ASCE TransmissionStructure Foundation Design Guide
The American Society of Civil Engineers' (ASCE) Subcommittee on Foundation Design for High-Voltage Transmission Structures was formed in October 1976. The purpose of the Subcommittee...
