Hydropower is the most natural form of energy generated in the World. It allows us to make use of our natural resources without pollution. It harnesses the basic fundamentals of nature...

Standard Safety and Control Concept for Double Regulated Small and Medium Hydro Turbines
The paper proposes a standard control concept for double regulated small and medium hydro turbines. The concept is based on minimum protection requirements for safe and reliable quick...

Electrical Design Survey
In North America, a mini hydro project consists primarily of the civil works which routes water to the turbine generator and the electrical hardware necessary to interface it with a utility....

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...

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...

Dam Safety Hydrologic and Seismic Evaluation of TVA'S Beech Dam
Beech Dam is part of the Beech River watershed resource development located in Decatur and Henderson counties in west Tennessee. The development consists of eight dams and approximately...

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....

Rocky Mountain Project Power Tunnel Filling Test
The Rocky Mountain Project, a pumped storage development located in NW Georgia, is owned jointly by Oglethorpe Power Corporation and Georgia Power Company. Initial construction included...

Sungai Piah Hydroelectric Project (Malaysia)
The Sungai Piah Hydroelectric Project is located in the State of Perak in Peninsular Malaysia. It is a run-of-river project on steep mountain streams in dense tropical jungle. Nine intakes,...

Rocky Mountain Project?Probable Maximum Floods
Probable maximum floods (PMF's) were estimated for use in designing spillways for the lower reservoir main dam and two auxiliary pool dams at the Rocky Mountain pumped-storage...

Utilizing Wetlands for Stormwater Retention
The design steps an engineer uses to develop natural wetlands to provide flood control while continuing to retain their natural functions will be analyzed. This paper will include a discussion...

Implications of the 1987-1990 Droughts for Hydropower Generation at Reclamation Powerplants
Droughts in the western United States beginning in 1987 have caused water supply shortages and required rationing of water in some areas. The reductions in water supply have also impacted...

Assessment of Changes at Glen Canyon Dam
This paper describes the complexity associated with the assessment of financial impacts of proposed and actual short-term restrictions at Glen Canyon Dam. The reasons for these restrictions...

Evaluating Hydro Project Benefits with the POWRSYM Production Cost Model
The contribution that a hydro peaking project or pumped-storage project makes to reducing system operating costs can be determined only by modeling the project's operation...

Consideration of Sedimentation on Hydropower Projects
Experience gained by analysis of a number of hydropower projects throughout the world leads to the conclusion that it is necessary to consider sediment related aspects in the design and...
