Hydraulic Model Tests of Flow around Penstock Suspended inside the Tunnel for Design of a Small Hydro
The proposed hydropower project in the State of Virginia involves design and construction of a steel penstock hung from the crown of an existing outlet tunnel at this U.S. Army Corps of...
Case Study Safety Evaluation of the Existing Wise Powerhouse Penstock
A 70-year old riveted penstock was analyzed to determine its actual design strength in response to the discovery of significant pressure rises under normal operating conditions due to...
Mitigation of Ice Effects at Hydroelectric Intake Structures
The design and operation of hydroelectric facilities throughout the northeast United States and Canada must contend with winter conditions for a large part of their yearly operation. During...
Licensing the Moose River Hydroelectric Project
This paper describes environmental considerations in the licensing and permitting of the Moose River Hydroelectric Project, a 12.2 MW development in Central New York State. It illustrates...
Optimum Use of the Water Resource a Factor in the Hydroelectric Relicense Process
To meet Federal Energy Regulatory Commission (FERC) requirements for a new license, owners must demonstrate full development of the available water resource. This paper presents an approach...
Utility Options for Meeting Dissolved Oxygen Limits for Hydroelectric Power Plant Discharges
Due to increased attention by regulating agencies to the dissolved oxygen levels of water released through hydroelectric power plants, the Electric Power Research Institute has developed...
Improvement of Dissolved Oxygen Levels at Shepaug Hydro Station
Discharge from Shepaug Dam in Connecticut fall below the state standard for dissolved oxygen in summer and early fall, because of thermal stratification of the upstream eutrophic reservoir....
Water Quality Studies for Hydro Licenses
Three case studies on the impact of hydro operation on dissolved oxygen concentration performed for hydro license applications are utilized in a discussion of water quality issues. A negative...
Tailwater Management for Beneficial Uses
Tailwaters can provide significant benefits for recreation, fisheries, assimilative capacity for treated wastewaters, and water supply for municipalities and industries. Development and...
A Water Quality Impact Analysis of a Hydropower Facility
A low-head hydropower generating facility has been proposed at an existing dam site on a river. The state environmental agency has required an environmental evaluation into the potential...
Balancing Hydropower Development in the Ohio River Basin
A large number of retrofit hydroelectric projects have been proposed at existing navigation dams in the Ohio River basin. These proposals involve potentially adverse environmental impacts,...
The Groundwater Studies for the Harrisburg Hydroelectric Project
The proposed Harrisburg Hydroelectric Project is a conventional 34.4-MW power facility located on the Susquehanna River in Harrisburg, Pennsylvania. The project will raise the river water...
Optimization of Power Production Based on Efficiency Data
Computer programs dealing with different parts of the optimization process are in operation in Norway today, and they include: the hydrological part from weather forecast to reservoir...
Hydroelectric Generator Rewinding Pitfalls and Means to Ensure Success
The failure or success of generator rewinding begins well before the actual rewind, and many of the pitfalls can be avoided if owners take some very important steps prior to the rewind...
Optimizing Joint Load Control for Hydroelectric Plants
This paper discusses a method to minimize water usage at a multi-turbine hydroelectric generating plant. At plants which do not spill water this optimization is directly converted to extra...
Efficiency Monitoring Yields Large Revenue Gains
This paper presents a Washington Water Power Company program to increase hydroelectric plant operations' efficiency. This increase is due to improved flow, head, and megawatt...
Upgrading Open-Wheel Pit Hydro Plants with Modern Submersible Hydroturbines
This paper presents a new approach in rehabilitating open-wheel hydrosites by using modern, standard submersible hydroturbines, open flume type cylinder gates, and high efficiency draft...
Murray?Commissioning Maxi Hydro with Mini Flow
The Murray Hydroelectric Project contains two of the largest pit turbines in the world. An existing dam constructed for navigation and flood control on the Arkansas River, Lock and Dam...
Turbine Efficiency Measurements by the Pressure-Time and the Current-Meter Method at Paugan
Paugan generating station was built in the 1920s. Although the generators were converted from 25 Hz to 60 Hz in the mid 1950s, the original runners were in place until recently when a...
Manicouagan 5?Additional Capacity Project
This paper, after presenting briefly the evolution of the peak demand characteristics of the Hydro-Quebec grid and what caused it, describes how newly installed capacity and equipment...
