A Hydroelectric Plant Operator's Assistant
This paper describes a PC based application designed to assist in the process of enhancing the performance of multi-unit hydroprojects. Optimization considerations, uses of the Operator's...
Ferroresonance & the Snettisham Hydroelectric Project
Key system features of the Snettisham power plant in Alaska will be highlighted along with a discussion of the operational problems encountered due to a ferroresonant condition. The project...
Economic Impact of Reduced High-Voltage Equipment Life
In May, 1989, the Western Area Power Administration and the Bureau of Reclamation published a report entitled Replacements: Units, Service Lives, Factors. This report showed that equipment...
Voltage Regulator Influence on Generator System Stability
During initial startup of a generator system, it is not uncommon to witness generator voltage instability. Most of the time, the solution is reduced to returning the stability control...
Design Considerations for Radial Key Retrofit
A practise that is becoming more and more common is to retrofit hydro-electric generators with Radial Key Systems. There are significant design considerations that must be made to ensure...
Varying Generator Excitation to Control Draft Tube Surge
The Bureau of Reclamation recently experimented with varying the excitation applied to a hydroelectric generator to control power swings caused by draft tube surging in a Francis turbine....
Repair of Rainbow Project Unit Number Eight
This is a case history that discusses diagnosis and correction of a AC synchronous generator problem. The problem involved loss of mechanical integrity between the generator's...
Rehabilitation and Replacement of Slab and Buttress Dams at the Wissota Hydroelectric Project
The Wissota Hydroelectric Project is a 70 year old slab and buttress dam which required rehabilitation due to deteriorating concrete. Due to restrictions imposed by the FERC and Owner,...
Rocky Mountain Project Seepage Cutoff in Solutioned Limestone
The right abutment of the main closure dam for the Rocky Mountain Project required extensive treatment of deeply weathered shale and solutioned limestone to assure control of seepage and...
Potholes East Canal Headworks Project
The construction of 6.5 MW Potholes East Canal Headworks in Washington required near vertical excavation of about 100 ft (30 m) through the existing earthfill dam founded on columnar basalt....
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...
