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...
Pumping System Permits Diversion of Water River Dam
For project construction at an existing Corps of Engineers' dam in New Mexico, where modifications to the existing outlet works were performed, a barge-mounted pumping system...
Buffalo Bill Dam Modifications?Modification of an Existing Bureau of Reclamation Facility to Increase Power Generation
This paper describes a joint venture between the United States Bureau of Reclamation and the State of Wyoming to increase the storage capacity and power generation capacity of Buffalo...
Transient Analysis of the Finchaa Hydroelectric Project
An iterative computer simulation procedure called LIQT (Liquid Transient), which performs simulations of hydraulic transients in closed conduit hydro-power systems, is used to estimate...
Hydropower Analysis Using Electronic Spreadsheets
A sequential streamflow routing procedure is recommended to overcome the inadequacy of the conventional duration curve analysis, especially in cases involving multiple intakes for capturing...
FERC Licensing: The Water Resources Engineers Role
As a result of the Electric Consumers Protection Act (ECPA) of 1986, the Federal Energy Regulatory Commission (FERC) is obligated to give equal consideration to non power uses of hydroelectric...
Analysis of Unsteady Flows in Irrigation Canals Due to Load Rejection in Hydroelectric Project
An add-on hydroelectric project has been proposed for the Owyhee Tunnel No. 1, a component of the Owyhee Irrigation Project constructed in the 1930's by the U.S. Bureau of...
Fluctuating Pressure Measurements on a Large Hydro Turbine
The New York Power Authority is investigating the feasibility of upgrading the thirteen 150,000 kW turbines-generators at the Robert Moses Niagara Power Station to improve efficiency and...
Renewal of the Burt Dam Generating Station
The present redeveloped hydro facility operates as a 300 kW run-of-river station automated by a head pond level controller which adjusts turbine setting to match available river discharge....
Environmental Engineering
The 1989 Specialty Conference on Environmental Engineering was held in Austin, Texas on July 10-12, 1989 with cooperation from the University of Texas at Austin Civil Engineering Department...
Building A Better Wetland
Nouri described an engineering plan designed for the National Audubon Society to restore the Ballona Wetlands of southern California, which has been severely degraded by population growth,...
Hydro on Hold
Hydropower projects have become the target of a growing environmental movement overseas. The tradeoff between clean, renewable energy and the possible environmental impacts of the reservoirs...
Big Trouble in Little America
Traditionally, rural communities in the U.S. have relied on septic systems to treat their wastewater. Many of the nation's 23 million septic systems, however, are failing....
Water Beneath the City Streets
Urban groundwater control requires high levels of skill and experience but allows for only a small margin of error. Determining the best method for controlling groundwater requires knowing...
