Advances in Controls to Govern Mini and Micro Hydropower Systems
Conventional controls available for small hydropower systems are surveyed. Electronic load controls for micro hydropower systems are described. Recent developments in the literature are...
Hydropower on the Arkansas?A Non-Federal Development
In 1980, Arkansas Electric Cooperative Corporation (AECC) filed preliminary permit applications with the Federal Energy Regulatory Commission for developing the hydropower potential at...
Relicensing/Renewal and Coordinated Consultation
A project which has been constructed and operating for a number of years offers a substantial set of empirical data for assessing how - and by whom - the project should be continued in...
FEM-Flow Analysis in Hydraulic Turbomachinery Runners
Finite element calculations of the flow through distributor and runner of hydraulic turbomachines are presented. The method is quasi-3D and inviscid, but the deviations from a potential...
The Bath County Pumped Storage Project
Virginia Power and the Allegheny Power System will introduce an important new peaking power service in late 1985, when the first unit of the Bath County Pumped Storage Station becomes...
Evaluation of a Pump-Storage Hydropower Facility
This paper summarizes the findings of the evaluations conducted by faculty of the University of Missouri and outside consultants regarding the downstream effects of Harry S. Truman Dam...
Roller Compacted Concrete and Tunnel Boring Machines?Two Tools for Designers and Planners
Two tools that have come into use fairly recently are roller compacted concrete and tunnel boring machines. These new tools can significantly affect the ability to make new projects cost...
Retrofitting Outlet Works of Existing Dams for Hydropower
This paper deals with three small hydroelectric plants installed at existing dams in California with moderately high heads (about 200 feet). In each case there was an overriding need to...
Power Value Determinations
Past and current federal methodology and procedures in power value determinations are presented for consideration by Western Area Power Administration (Western), U. S. Department of Energy...
Hoover Dam Planning, Financing and Repayment
After the original conception of the 'Boulder Canyon Project,' and in the first stage of the work, complete designs and specifications were prepared for the dam,...
Insuring Security Requirements of Power Contracts
Under the fixed, or levelized rate utility contract, utility offers a fixed rate for the life of the contract. In the early years, the rate is in excess of the utility's avoided...
Control System Design Considerations for Small Hydro Projects
This paper deals with the philosophy that must be embraced when specifying a fast track small hydro project. The major areas discussed are: the role of control systems in the context of...
Uprating Francis Turbines Provides Additional Energy
The use of existing powerhouse, penstocks, dams and unit configuration, all provide for a quick cost effective method to increase output from an existing turbine installation. This paper...
The Twlefth Street Project?Multiple Uses on the Falls of the James River
This paper is about a hydroelectric project that was not built. The project is located in Richmond, Virginia on the James River. Project civil works, water rights and adjacent land are...
Design of Modular Structures for the Arctic
Sohio's efforts to continue the production and initial processing oil from Prudhoe Bay, Alaska requires additional production enhancement equipment on the Alaskan North Slope...
Characterization of the Dalton Highway Foundation Soils
A case study is presented of the landform-based probabilistic-statistical route geotechnical characterization of natural foundation soils along the Dalton Highway. Landforms were mapped...
A Thermal Analysis of Pavement Thawing
This research focuses on identifying the spring thawing period for the purpose of timing load restrictions on low to medium volume roads in frost-susceptible areas. Cases evaluated include...
Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....
Wastewater Plant Cold Weather Operational Problems
A questionnaire survey was conducted at biological wastewater treatment facilities in northern New England. Problems associated with various unit processes, due to cold weather operations,...
Finite Element Modelling of Cold Regions Concreting
Finite element heat transfer computer programs are discussed in regard to their use in modelling cold weather concreting. The concrete material properties required for input to the finite...
