Some Pertinent Considerations in Dam and Reservoir Design
Two important considerations in designing and constructing a multipurpose earthdam and reservoir are to minimize losses in the event of dam failure because of overtopping, and to conserve...
Thermally Developed Blade Stresses and Cavitation Damage
Cavitation damage to the turbine runner blades, to the draft tube liner, and to the runner hub requires extensive welding repair. The traditional repair method is to gouge out the damaged...
Automation of Existing Dam Control Schemes
For installations that are already in operation, the following advantages are obtained from installing new electronic equipment: In the case that the dam or certain measuring stations...
Management System for Power Plants Tecaid Maintenance System
Operational conditions and production levels are maintained at consistently higher levels when a planned maintenance system is used. Initial operational expenses for a planned maintenance...
Lopez-Angostura Power Tunnel
The Lopez-Angostura Project is located on the Yaque del Norte River in the Dominican Republic near the City of Santiago. A 24 m high dam, a 3.6 km long power tunnel, a pit powerhouse with...
Design of Steel Tunnel Liners
The paper presents a detailed development of the fundamental equations for internal pressure design, considering an elastic interaction between the steel liner and the surrounding rock...
The Modification of Leroy Anderson Dam
An extensive modification program has been implemented to improve the safety and enhance the performance of the Leroy Anderson Dam. The Leroy Anderson Reservoir has a maximum storage of...
Analysis and Rehabilitation of Ambursen Dams
This paper deals with the investigation and analysis of two Ambursen dams located in the upper Midwest. These investigations revealed that the original design contained significant defects,...
New Clues to PMP
Great changes have occurred in meterology in the last two decades. Formerly, weather data were available for forecasting and climatological analyses only at points - at weather stations....
Regional Rivers Resource Assessment as a Tool for Hydropower Planning and Policy: The Pacific Northwest Rivers Study
In August, 1984, the Bonneville Power Administration (BPA) and the Northwest Power Planning Council (Council) initiated a study to provide information about important river characteristics...
Clay Joints in the Foundation of Dkhila Dam
The stability analysis performed at the beginning of construction, taking into account the shear test results of the foundation claystone showed insufficient safety factors against sliding....
HYOPS?Maximizing the Value of Your Hydro River System
This paper presents a microcomputer based software system, HYOPS, to optimize the operations of a series of hydro plants on a river system. The model can accommodate up to 10 plants which...
Instream Flow and Energy Production Studies for Hydro Relicensing
A methodology for assessing the effects of alternative flow release scenarios on both aquatic habitat and on energy production was utilized during instream flow studies at a 72-MW hydroelectric...
Bonneville I Powerhouse Station Service Unit Rehabilitation
This paper presents the work being done towards the rehabilitation of the Bonneville I station service unit. The rehabilitation of this unit includes a generator rewind, excitation system...
Vertical Axis Hydro Turbines for Off Grid Installations
This paper describes the design, manufacture and testing of a 5 kW floating VAHT for use in tidal, ocean, and river installations. This work is based on the results of research contracts...
Retrofitting of Hydro Electric Generators with Bus Fed Solid State Excitation Systems
The Northern Hydro Division has completed retrofitting the excitation systems on 22 generating units ranging in output from 1 to 95 MWatts. The Big Creek Hydro Project upgraded these systems...
Optimizing Joint Load Control for Hydroelectric Plants
This paper discusses a method to minimize water usage at a multi-turbine hydroelectric generating plant. At plants which do not spill water this optimization is directly converted to extra...
