Layout of a Powerhouse Adjacent to Lock and Dam Structures
An approach flow to a powerhouse intake adjoining existing lock and dam structures may cause a significant reduction in the efficiency of the powerhouse and give rise to an economically...
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,...
Experimental Investigation of the Cross Flow Turbine
A laboratory model of the Cross Flow Turbine was investigated in the Hydraulics laboratory of Colorado State University. Because of the successful use of this turbine in the developing...
An Integrated Site Controller-Network Monitoring System for Small Scale Hydroelectric Sites
Over the past decade more and more small scale hydroelectric power developers have faced the question of the economic feasibility of installing microprocessor based control systems for...
Influence of Surface Finish on Thrust Bearing Life
The original pivoted pad thrust bearing installed and fitted at the Holtwood Power Station in 1912 by A. Kingsbury has been operating continuously since that time without any difficulty....
Accelerated Life Testing of Generator Coils
This paper presents a step-by-step procedure for doing a 400 hour, 60 Hz, 90 degree C accelerated life test on generator coils. Test procedure is as follows: 1. Initial coil examination...
Fretting Corrosion on Large Split Thrust Bearing Runners
In the early fifties interfacial slip was measured on laboratory models. Design improvements, resulting from these tests, were incorporated into later machines. These improvements appreciably...
Upriver Dam Hydroelectric Project Rehabilitation After Failure, Part A: Failure Investigation and Lessons to be Learned
A lightning strike caused electrical failure at Spokane's two Upriver power plants, resulting in the river overtopping Project embankments, and causing nearly 11. 5 million...
Upriver Dam Hydroelectric Project Rehabilitation After Failure, Part B: Rehabilitation and Enhancement of Project Civil and Mechanical Facilities
A feasibility investigation of rehabilitation alternatives was conducted which identified several alternatives for repairing the damage and placing both powerhouses back on-line. These...
No. 1 Water Wheel Project, Gilman, Vermont
This paper describes the replacement of an old generating unit with a new unit in a turn-of-the-century mill building where three other such units were already operating. The key issues...
Hydropower Goes Downtown
Beneath a busy street in Southern California seems an unlikely location for a small hydroelectric generating plant. However, located just below El Segundo Boulevard in the town of El Segundo...
After L'Ambiance Plaza
In the aftermath of the tragic collapse of the L'Ambiance Plaza apartment building at Bridgeport, Conn., in April 1987, reforms are being proposed. In 1987 ASCE approved writing...
The European Underground
Three tunneling projects in Europe are described: a tunnel bored under two rivers in Lyon, France, a subway station constructed as a mined tunnel in Vienna, Austria and a tunnel mined...
