The Use of Interior Guide Tube in Cross Flow Turbines
The Cross Flow Turbine has the distinct advantage of lower initial and operating costs over other small scale turbines, but it is believed to lack somewhat in efficiency. In this study...
Considerations to Be Taken in the Design of Speed Increasers for Hydroturbine Service
The paper discusses the incorporation of a speed increaser specification that is primarily functional yet one that will address the cost, reliability, efficiency, and life requirements...
Hydro Turbine Submergence
The elevation of a hydro-electric turbine above or below tailwater is based on hydraulic model studies to determine the critical sigma, defined as the ratio of barometric pressure plus...
Pit Turbines, an Economical Solution for Low Heads
The paper describes the experience with pit turbine design and construction at the 8 MW St. Cloud facility located on the Mississippi River in Minnesota. Major topics in the paper include...
Design and Efficiency Testing of a Cross-Flow Turbine
An inexpensive American-made cross-flow turbine was designed, manufactured, and installed at a remote run-of-river site in Northern California. The 400 kW unit includes an innovative automatic...
Harnessing the Allegheny: Four Low-Head Projects
The navigable portion of the river, extending northeast of Pittsburgh approximately sixty miles, contains eight lock and dam systems under the jurisdiction of the U.S. Army Corps of Engineers...
Turbine Conceptions for Low Heads and Their Application in US Hydro Power Stations
To improve the feasibility of small power plants standardized units were developed. The bulb turbine technology as well as the pit-type conception improve the feasibility of larger plants....
Asphalt-Rubber Concrete?A New Horizon
The performance of asphalt concrete pavements is dependent to a large degree upon the rheological properties of the asphalt binder. Asphalt-rubber as a binder material extends the temperature...
Movable Dam?Gate Selection Procedure
Very few new dams are now being considered, particularly for waterpower and even more specifically for low head waterpower in the lower reaches of major rivers. The City of Harrisburg,...
Influence of Three Sonic Devices on Fish Behaviour
Three sound emitting devices have been developed to control fish movement in the vicinity of generating stations. These devices have the advantage of increased flexibility in terms of...
Fish Mortality at a New Low-Head Hydroelectric Plant
A study was developed for the Morrow Plant to investigate the potential for turbine related mortality of entrained fish. Morrow Lake supports a small sport fishery, mainly for smallmouth...
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...
Designing a Modern Small-Scale Hydroelectric Plant
STS Consultants, Ltd. (STS) and Skidmore, Owings & Merrill (SOM) successfully teamed on four hydropower sites in Michigan during the 1980's. Three of the four sites...
Status and Prospectives of Small Hydro Power Development in Egypt
The paper describes the current status of hydropower development in Egypt and its future prospects. Emphasis is made on reviewing the potentialities for small, mini and micro-hydropower...
Design of Siphon Penstocks for Low Head Hydros
Siphon penstocks have been designed and constructed at Jim Falls and Winter, Wisconsin at existing dams. Both hydropower projects are located on the Chippewa River. The design of these...
Adapting Tunneling to Rocks of the Sierra Nevada
Exploration programs were completed to select the most economical tunnel routes which are not only the shortest but are those which can be excavated by tunnel boring machines with the...
Sidney A Murray Jr. Hydroelectric Project
The Sidney A Murray Jr. Hydroelectric Project is being designed and constructed by EBASCO Services Inc. for the City of Vidalia (La) - Catalyst, Old River Hydroelectric Ltd Partnership....
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...
