Computerized Operation Models of Oroville Reservoir
Two monthly computer operational models, OROTHM1 and OROTHM2, were developed to provide more detailed operation and maintenance studies for the Oroville facilities. Currently another computer...
Hydrologic Dispatch Model for a Hydropower System
A hydrologic dispatch model was developed for an 11 plant, six reservoir hydroelectric system. The model incorporates load forecasting, system dispatching strategy, and database management...
Stochastic Optimization of Reservoir Systems Operations
This paper addresses the stochastic optimization of real-time monthly operations of multi-reservoir systems by Dynamic Programming. A two-stage optimization framework that consists of...
Development of Hydroelectric Scheduling Model
This paper presents the proposal preparation, pre- and post-award negotiations, and the engineering and computer software development of an hourly generation scheduling model. The Western...
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...
Estimating Hydroelectric Operation and Maintenance
To improve the estimating of operation and maintenance costs for new small hydroelectric projects, an estimating model was developed. This model listed all of the operation and maintenance...
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...
A Mathematical Model for Traveling Screens at Hydropower Plants
Hydroelectric projects cause significant mortality to fish migrating downstream. The current method to reduce fish mortality at hydropower plants is the use of traveling screens. In this...
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...
Long Lake Dam Model Studies
The Long Lake spillway was designed at the turn of the century as a standard ogee section with an upstream batter for a maximum head of 179 feet (55 m). It did not include any energy dissipator....
Mountain Jungle Intakes?Design and Model Study
Nine intakes of various sizes and designs supply water to the two high head power plants in the Sungai Piah Hydroelectric Development in Malaysia. The intakes are located on steep mountain...
The Role of Model Studies in Add-On Hydro Projects
The reasons for modeling add-on projects are reviewed, and guidance given for the process of determining, first, the need for modeling, and second, if modeling is necessary, whether physical...
Hydropower at Navigation Projects
Hydropower at navigation projects has been found to be compatible with the intended use of the project; however, it is important for the hydropower developer and the project owner to be...
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...
Low Head Hydraulic Model Justifies Cost
In many cases, developers of low head hydroelectric plants fail to use physical hydraulic modelling as a tool in the design process. Economic constraints are often cited as the primary...
Model Studies for Potential Modification of Pardee Spillway
East Bay Municipal Utility District, a public water supply agency in the San Francisco Bay Area, is examining the spillway adequacy of its primary water supply reservoir. Flood routing...
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...
Rehabilitation of a High Specific Speed Francis Turbine
An upgrade of two (2) 4. 06 meter diameter high specific speed Francis turbines is now in progress. These machines were originally installed by Allis-Chalmers in the 1920's...
Racine?5 Years of Successful Operating Experience with the World's Largest Bulb Turbines
In September 1982 two bulb turbine generating sets with a runner diameter of 7700 mm and a generator rating of 25 MVA were put into commercial operation at the Racine dam on the Ohio river....
