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...
The Design of the Outlet for the New Koepchenwerk Pumpstorage Plant
The Koepchenwerk Pumpstorage Plant (1930) is going to be replaced by a new plant with a 150 MW Pumpturbine in a shaft. This paper explains the reasons for this replacement and gives a...
Bath County Tunnel System/Remedial Treatment Program
The Bath County Pumped Storage Project, owned jointly by Virginia Electric and Power Company and Allegheny Generating Company, is located 70 miles (112 km) north of Roanoke, Virginia....
Variable Speed Generators in Hydro Applications
This paper discusses the investigation of the doubly-fed variable speed machine as a potential candidate to convert a varying input speed to a constant frequency, constant voltage output....
Research and Development Program on Small Scale and Low Head Hydro by the Canadian Government
In July 1985 the Canadian Department of Energy, Mines and Resources (EMR) was assigned the responsibility for the federal support program for renewable energy R&D in Canada. In...
Analysis of Hydraulic Transients for Design and Operation of Two Powerhouses in Series
The Dinkey Creek Project will be located in the southern Sierra Nevada mountains 40 miles north-east of Fresno, California, and will develop about 4000 ft of gross head with a maximum...
Design and Operation of a Differential Surge Tank
The differential type of surge tank is more effective in operation than the simple type because it reacts more quickly to load changes of all sizes. The differential tank is also usually...
Development of Three Systems Operated Rev. Pump Turbine
In order to represent the development of reversible, single stage pump turbines in Yugoslavia, the three systems operated pump turbine (3SRPT) of the fourth unit of Moste hydro power plant,...
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,...
Generator/Motors and Adjustable-Speed Drives for Waddell Pumped-Storage Plant
This paper describes the pumping and generating units and associated electrical equipment planned for Waddell Pumped-Storage Plant. Waddell Pumped-Storage Plant is to be located near Phoenix,...
Electrical Equipment for Pumped Storage Plants
Selection of generator/motors and other electrical equipment for pumped storage plants requires consideration significantly different than for conventional hydro plants. This is particularly...
Pyrites Hydroelectric Project, Canton, New York
This paper describes the Pyrites Hydroelectric Project in Canton, New York, an 8-MW project completed in December 1985. The key to its successful development was a team approach that included...
Roller Compacted Concrete Mix Design for Pamo Dam
Pamo Dam is designed as a 265 foot (81M) high gravity dam that will be located on the Santa Isabel Creek in San Diego County, California. RCC volume will be approximately 491,000 cubic...
RCC Pavement Construction and Quality Control
In October 1986 a 16,500 sq yd (14,300 sq m) roller-compacted concrete (RCC) pavement tank hardstand, the first of its kind in Europe, was built for the U. S. Army at Harvey Barracks in...
Extent of Water Quality Effects of Dams?A National Viewpoint
An overview of phosphorus impacts on impoundments, a subset of the contents of the Dam Water Quality Report is presented. The U.S. Environmental Protection Agency (EPA) is the lead investigator...
Reservoir Safe Yield Evaluation Using Simulation
The safe yield available from surface water impoundments serving the City of Portsmouth, Virginia, was evaluated, and the sensitivity of the reservoir system to several factors was investigated....
Risk Consideration in Water Supply Reservoir Capacity Design
This study develops a method for estimating the risk in reservoir capacity design by applying frequency analysis to the mass curve method. It provides a means for the engineer to use familiar...
