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...

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...

Early Detection of Rotor Cracks?Monitoring & Methodology
This paper describes a diagnostic method for the early detection of shaft cracks on rotating machines. The method is based on interpretation of the lateral synchronous (1x) and twice per...

Generators with Shaft Mounted Turbine Runners
Water turbine runners mounted on an extended generator shaft are often specified to eliminate turbine bearings and the flexible shaft coupling. Two bearing single shaft turbine generator...

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...

Design Data of Pump-Turbine and Francis Turbine Units
Some basic statistical data covering geometrical and energy parameters for Francis turbine and Pump-turbine units are presented. These data are further compared as specific ratios for...

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,...

Turbine Efficiency Monitoring Utilizing Ultrasonic Flowrate Measurement
On-line turbine efficiency measurement can be achieved by ultrasonic flowrate measurement and state-of-the-art data acquisition techniques. A field performance test program conducted at...

Field Testing: Producing Complete Test Results on Site, A Realistic Objective
Modern technologies and instruments have had an influence in nearly every field imaginable. At Hydro-Quebec, the last ten years have brought about a complete transformation in the way...

Hydro Machinery Problem Solving Experiences
Within the last decade the use of modern data acquisition instrumentation and techniques have moved the subject of the machinery problem solving into a more scientific arena. This paper...

Index Testing With a Data Acquisition and Control System
A computer controlled index test has been developed that can be used to optimize blade-gate relationships on adjustable blade (Kaplan) hydraulic turbines. This paper includes hardware...

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...

Basic Considerations in Governed or Non-Governed Small Hydro Power Plants
This paper reviews the necessary studies and major considerations that must be completed for proper coordination and selection of a turbine governor, and generator. A discussion of the...
