Intakes for Low Head Hydro Plants
The design of hydro intakes is usually based on a desire to achieve low intake losses and an acceptable approach flow distribution to the turbine. Generally, velocities in the intake canal...
Fish Diversion in Hydropower Intake
Hydraulic model studies were conducted to develop a fish screening system to be used in the turbine intakes of Priest Rapids Development on the Columbia River, Washington. The system studied...
Vortices at Vertical Intakes
This paper presents the results of an experimental investigation designed to predict the formation of weak, free-surface vortices at vertical intakes with a headrace channel. A weak vortex...
Hydraulic Study Requirements for Bulb Type Hydropower Units at a Navigation Lock and Dam
A replacement Lock and Dam at Alton, Illinois on the Mississippi River is presently under construction. This paper presents the results of studies performed for adding six bulb type hydropower...
Karnafuli Hydroelectric Project, Hydraulic Model Studies of Spillway Damage
The Karnafuli Hydroelectric Project is located in Bangladesh. On August 13, 1961, distress was noted in the spillway flow. A special Board of Consultants considered possible causes for...
Make-up and Blowdown of a Cooling Pond
A mathematical model was developed to simulate the operation of a recirculating cooling pond for a planned nuclear power plant in the Midwest. The objective of the pond operation is to...
Hydraulics of Broad Crested Weirs
The paper presents a general, basic discussion of the title subject. It begins with a definition for the broad crested weir and analytical concepts. Subjects covered subsequently include...
Velocity Distribution Factor Constraints
It has been customary to introduce the velocity distribution factors alpha and beta into the energy and momentum equations so as to avoid the integration associated with variations in...
Analysis of Resonance in Pressurized Piping Systems Via a Microcomputer
In this paper a digital simulation technique for the analysis of resonance is presented that is appropriate for microcomputer applications. The model utilizes the transfer matrix method...
Automated People Movers?The Need for Flexibility and Clarity
The Airtrans System at Dallas/Ft. Worth Airport is the best example available of how an automated people mover (APM) might function in an urban setting. An examination of Airtrans shows...
Hydropower's Newest Generation
Higher energy prices and strong incentives from the federal government have caused hydropower developers to consider sites that just a few years ago were scoffed at as mere trickles. Intense...
Transmission Tower Foundations in Weathered Rock
A case history is presented which discusses the siting, design and construction of the tower foundations for a transmission line in southwest Alaska. The project, completed in 1983, consists...
Forecasting the Demand for Electricity: An Examination of Alternative Approaches
This paper examines several approaches to forecasting national-level electricity demand. The various approaches are briefly examined, and the strengths and weaknesses of each are discussed....
Energy Forecasting Techniques: An Overview
This paper provides an overview of the primary forecasting techniques employed by electric and natural gas utilities to predict energy consumption and demand. Although the techniques discussed...
The Role of Demand Forecasts in Pacific Northwest Power Planning
This paper has two primary objectives: to acquaint a general audience with the basic approaches used to forecast the demand for electricity, and to discuss the role of demand forecasts...
The Impact of Demand-Side Management on Load Growth: Some Tentative Results
Demand-Side Management (DSM) programs including load management, conservation and strategic load growth are being implemented by a very large number of utilities for the mutual benefit...
Control of the Design Process
Gilbert/Commonwealth, Inc. (G/C) was the architect-engineer for the original design of the Florida Power Corporation (FPC) Crystal River Nuclear Plant, Unit 3 (CR3) and has been involved...
The Hydroelectric Barge
The nation's inland waterway system includes many low head locks and dams, with undeveloped hydropower potential estimated in excess of 1,100 MW. For most of these dams, hydro...
The PowerBarge Hydroelectric Plant
Following an account of the need for such an approach, the PowerBarge hydroelectric plant design concept is described as a fully floating system consisting of an Intake Barge, Siphon Penstock,...
Libby Rereg's Combined Spillway and Powerhouse
The existing powerhouse at Libby Dam, located near Libby, Montana has four generating units for a total of 420 MW. Provisions have been made which will allow doubling the plant rating...
