Using IFIM at the Upper Greenwich Project and Other Hydropower Developments
The Instream Flow Incremental Methodology (IFIM) is widely used at numerous hydroelectric projects today for determining flow releases. IFIM is capable of quantifying changes in aquatic...

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...

Computerized Measurement of Turbine Flow and Performance, Including Penstock Protection
The application of computer technology now makes it possible to measure turbine flows accurately, reliably and economically. The measurement is based on the differential pressure produced...

The Use of Interior Guide Tube in Cross Flow Turbines
The Cross Flow Turbine has the distinct advantage of lower initial and operating costs over other small scale turbines, but it is believed to lack somewhat in efficiency. In this study...

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...

Oil Hydraulic Design for Turbine Control
The paper addresses three areas of Oil Hydraulic Design for Francis and Kaplan Turbines: smart accumulator condition sensors, high flow servo logic, and high pressures Wicket Gate cylinder...

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...

Acoustic Flowmeter/Efficiency System Installation at the Niagara Power Project
The New York Power Authority's Robert Moses Niagara Power Project (RMNPP) recently installed an acoustic flowmeter/efficiency system on two 150 MW rated generators. This paper...

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...

Design and Efficiency Testing of a Cross-Flow Turbine
An inexpensive American-made cross-flow turbine was designed, manufactured, and installed at a remote run-of-river site in Northern California. The 400 kW unit includes an innovative automatic...

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...
