Power System Study to Determine Hydro Benefits
This paper discusses evaluation methodologies used by Stone & Webster to determine the power benefits for six potential hydropower projects at existing U. S. Army Corps of Engineers...

Reliable Operation of Hydro-Thermal Power Systems
The demonstrated model allows planners to account for both operating and shortage costs, subject to a constraint on the system failure rate. In addition, the optimal long-term operation...

Pumped Storage and Power System Operations
The 2100 megawatt Bath County pumped storage power station began commercial operation in December 1985 as a jointly-owned project of Virginia Electric and Power Company (Virginia Power)...

Computer-Aided Operation of a Hydropower System
This paper outlines the development of a computer model which optimizes the operation of a regulated river system given certain constraints using an adaptive deterministic linear programming...

Hydrologic Design Methodologies for Small-Scale Hydro at Ungauged Sites
IMP is a microcomputer package for evaluating small-scale hydroelectric power sites in British Columbia. With IMP it should be possible for an experienced hydroelectric engineer to make...

Estimating Streamflow Characteristics for Micro-hydro Sites in Northwestern Oregon
Assessing hydropower potential requires knowledge of the streamflow characteristics at prospective sites. Gaging stations are often unavailable. A method for estimating streamflow characteristics...

The Use of Time Series Analysis to Estimate Flow Duration Curves to Assess Energy Potential for Low Head Hydro Redevelopment
The proposed hydroelectric site location has a low head potential making discharge the primary energy production component. A flow duration curve (FDC) study was commenced to generate...

Repair of The Hinckley Dam Embankments
The New York Power Authority was licensed in 1982 to construct and operate a 9 Mw hydroelectric facility at the existing Hinckley Dam near Utica, New York. Soil exploration programs undertaken...

Dam Safety Emergency Action Plans?A TVA-State Responsibility
The Federal Guidelines for Dam Safety requires each dam owner to prepare and maintain emergency action plans (EAP) for each of structure. These plans are necessary (1) to identify problems...

Modern Technology in an Ancient Environment?The Answan II Power Plant
The Aswan II power plant is located at the old Low Aswan Dam in Southern Egypt. This dam was constructed in the early years of the century in order to provide irrigation water for cash...

Murray Hydro Project?Structural Design
This paper will summarize design criteria, parameters, methods of analysis, and other relevant data that were used in the design process of the structural features of the Murray powerhouse...

Hydro Combine Option for Lakhwar Project
A new concept of providing a power house cavity inside the traditional gravity dam section has been explored. Preliminary investigations indicate that taking into account all the relevant...

Flow Calculation in a Francis Runner
The flow through a Francis runner has been analysed theoretically. The flow calculations have been carried out by use of an inviscid 3D computational method solving the Euler-Equations....

The Value of Model Testing in Computer Aided Pump and Turbine Design
This paper discusses the importance of model testing for development and sharpening of interpretive techniques through which computational codes can be effectively used for the design...

Selection of Turbine Diameter and Speed for Francis, Kaplan, and Pelton Hydraulic Turbines
This paper is a continuation of work presented at WATERPOWER '83 and presents up-to-date information on the selection of diameter and speed for Francis, Kaplan, and Pelton...

Major Hydraulic Turbine Operation and Maintenance Problems Experienced by the Corps of Engineers
The U. S. Army Corps of Engineers is the largest owner/operator of hydroelectric power generating facilities in the United States with 344 generating units, having an installed capacity...

Synopsis of Harry S. Truman Turbine Repair
The Harry S. Truman Powerplant was designed and constructed under the supervision of the U. S. Army Corps of Engineers and is located on the Osage River near Warsaw, Missouri. During 1981...

Field Observations of Cavitation Erosion in Hydraulic Turbines
Field surveys of the operational and design characteristics of 602 hydroturbines installed since 1950 and having a capacity in excess of 20 MW or a discharge diameter greater than 3 meters...

Computer Aided Design of Butterfly Inlet Valves
Computer simulation of butterfly inlet valves (throughflow, lattice) in hydropower schemes is presented. The software is intended for practisting engineers to obtain significant parameters...

Fire Protection at the Grand Coulee Hydro Project
In the fall of 1980 a rupture of one of the Project's 525kV transmission cables occurred and created a fire. Power from three Third Powerplant 700MW units was interrupted,...
