Techniques for Balancing Instream Flow Needs with Project Operation
Balancing power and non-power benefits of hydroelectric developments has become a controversial issue in the relicensing of projects. Multiple project and multiple objective flow management...
Harrisburg Hydroelectric Project?Water Quality Issues
The Harrisburg Hydroelectric Project is a proposed 34.4 MW hydroelectric facility on the Susquehanna River near Harrisburg, Pennsylvania. The project will consist of a 16.5 ft high gated...
EPRI's Pumped Storage Planning and Evaluation Guide
EPRI's Pumped Storage Planning and Evaluation Guide was published in 1990. The Guide provides step-by-step procedures to: (a) evaluate pumped-storage operation in a utility...
Hydraulic Model Studies for Non-Federal Projects at Federal Dams?A Case Study
This paper will discuss the hydraulic model studies for hydropower projects developed by Arkansas Electric Cooperative Corporation (a non-federal entity) at existing Corps of Engineers...
Overcoming the Obstacles?Hydroelectric Development on the Kankakee River
A number of difficulties were encountered and resolved during development of a 1,200 kW hydroelectric project in northeastern Illinois. Located at the site of an abandoned hydroelectric...
Undeveloped Hydropower Resource Potential
The public hearings conducted as part of the National Energy Strategy produced testimony that concluded that the potential for development of hydropower was not well defined. As a result,...
Load/Resource Matching for Period-of-Record Computer Simulation
The Southwestern Power Administration (Southwestern), an agency of the Department of Energy, is responsible for marketing the power and energy produced at Federal hydroelectric power projects...
Computer Modeling of Reservoir Sedimentation and Sluicing
A recently developed computer program which simulates the evolution, growth, and movement of a submerged delta in reservoirs was tested for Spencer Dam and Reservoir in Nebraska. The code,...
Decision Rules for Reservoir Releases
One of the problems faced with computer modeling of a multi-reservoir, hydro-power system is making decisions on how releases will be made. Reservoirs many times have multiple demands...
The Wisconsin River System Operations Model: WIRSOM
The passage of the Electric Consumers Protection Act of 1986 requires the Federal Energy Regulatory Commission to give equal consideration to non-power as well as power values in hydroelectric...
A Flow Forecasting System for Hydro Power
The flow forecasting system comprises a network of meteorological stations, a weather forecasting model, and a watershed hydrologic model, implemented in a microcomputer. The meteorological...
Calculation of Three-Dimensional Turbulent Flow in Francis Turbine Runner
A numerical scheme, based on MacCormack's predictor-corrector explicit finite volume method, for solving three-dimensional weakly compressible inviscid, laminar, and turbulent...
Development of a New Hydraulic Design Tool for Spiral Casing/Distributor Geometry
A novel computational model has been developed to predict highly complex turbulent flow in a combined spiral casing/distributor geometry. Validation of the computational model against...
Optimal Real-Time Control of Hydroelectric Power Plant Using Dynamic Programming
In this paper, an approach of optimal real-time control of hydroelectric power plant operations is presented. The methodology is based on a dynamic programming technique where the original...
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
