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...

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...

Validation Studies on Indexed Sequential Modeling for the Colorado River Basin
A method called indexed sequential modeling (ISM) has been developed by the Western Area Power Administration to estimate reliable levels of project dependable power capacity (PDC) and...

Operation of Hydropower Plants Considering Daily Streamflows
Operation of hydropower plants is a sequential decision process often modeled as a dynamic programming problem. Typically, such formulations consider monthly stages assuming that monthly...

An Artificial Intelligence Approach to Multiple Reservoir Operation
The modeling of complex river basins using symbolic computer languages, object-oriented programming and knowledge-based reasoning facilitates, the application of optimization techniques...

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...

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....

Colorado River Probable Maximum Floods
Upper limit design rainstorms (ULDRS) were developed for three locations in the Colorado River drainage above Hoover Dam. For each location, the rainfall magnitudes, spatial and temporal...

Three Dimensional Modeling of Concrete Dams with Cracks Using Boundary Element Methods
Determining uplift pressure distributions in cracks in a concrete dam requires coupling between crack hydraulics and the stresses and displacements occurring in the rock and the concrete...

Diversion of the Parana River for the Yacyreta Hydroelectric Project
The diversion and closure of one of the world's largest rivers, the Parana River on the border of Paraguay and Argentina, for the 2760 MW Yacyreta Hydroelectric Project, sponsored...

Hydraulic Model Studies?Pak Mun Hydroelectric Project (Thailand)
The paper presents briefly the hydraulic problems related to the project which were successfully solved by the 1 to 100 scale hydraulic model study carried out at the Asian Institute of...

A Rocky Mountain Project Intake/Discharge Channel Flow Simulation Study
A two-dimensional depth-integrated finite element flow model was applied to evaluate pumping and generating flow conditions at the Rocky Mountain Project powerhouse intake/discharge channel....

Physical Hydraulic Modeling for Construction of New York State Dam Hydroelectric Project
The New York State Dam is located on the Mohawk River near its confluence with the Hudson River. Downstream from the dam, the river flow is divided into four main channels as the water...
