Hand Held Powerhouse Control Console or Portable Data Terminal
The Portable Data Terminal (PDT) is a very small light weight hand held computer terminal that communicates with the control system computer by radio. An operator monitors power plant...
Optimising Electric Power From a Small Scale Hydro Plant
The paper summarizes new development in electrical power generation from small scale hydro prime movers. It describes various methods of power generation such as CSCF (Constant speed constant...
Measurements of Time Lag in Concrete Gravity Dam Foundations
Uplift measurements from eight large concrete gravity dams show that the time lag between an increase in headwater level and a corresponding increase in uplift pressure is insignificant....
Geotechnical Aspects of the Underground Excavations at the Kemano Completion Project
The Kemano Completion Project is the addition of four generators of 540 MW installed capacity to an existing eight-unit underground hydroelectric generating station owned and operated...
Soil Nails as Temporary Powerhouse Support
Newcastle Powerhouse was constructed as an underground structure with its top deck at the finished ground surface. The powerhouse is three-quarter circular and one-quarter square in plan....
An Alternative Approach to the Maximum Flood Concept
This paper outlines an alternative to the current approach for determining the maximum flood of river basins. The condition of the maximum flood is derived from the convolution integral...
The Stabilization of Minidoka Powerplant and Dam
The rehabilitation of structures can pose numerous challenges to the engineer. The structure historical preservation, the benefit cost ratio of the rehabilitation, and the stability of...
Seismic Analysis of the Bonneville 1st Powerhouse
The Bonneville 1st powerhouse monoliths were constructed during the period of 1938 to 1942 and were designed against seismic loads using the old lateral coefficient method. The Corps of...
Estimating Uplift in Cracks in Concrete Dams
Results are presented of a three year research program on the modeling of uplift pressures in cracks in concrete gravity dams, and the effectiveness of drains in reducing those pressures....
Dam Stabilization/Modification at Lighthouse Hill and Schuylerville Hydropower Developments
Remedial measures including posttensioning of concrete structures, earth dike armoring, tainter gate modification and replacement of deteriorated concrete to meet federal and state hydraulic...
Analysis and Stabilization of Ambursen Dams?Two Case Studies
Case studies are presented about the analysis and rehabilitation of two slab-and-buttress (Ambursen) dams. The paper discusses the investigation techniques used, including sampling of...
The Replacement of Penstocks at TVA Ocoee II Power Plant
The Tennessee Valley Authority (TVA) replaced the steel penstocks at its Ocoee II power plant near Ocoee, Tennessee. A total replacement was necessary because of severe corrosion on the...
Rehabilitation of the Dams at the Crescent and Vischer Ferry Hydroelectric Projects
This paper reviews the dam rehabilitation design and construction techniques used at the New York Power Authority's Crescent and Vischer Ferry Dams. The following are the...
Outlet Works Modifications at Abiquiu Dam
For the installation of a hydroelectric project at the Corps of Engineer's Abiquiu Dam in New Mexico, outlet works modifications that would not affect the structural integrity,...
