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...
Retrofitting of Hydro Electric Generators with Bus Fed Solid State Excitation Systems
The Northern Hydro Division has completed retrofitting the excitation systems on 22 generating units ranging in output from 1 to 95 MWatts. The Big Creek Hydro Project upgraded these systems...
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...
Electrical and Mechanical Design, Commissioning, and Performance of the Moose River Hydroelectric Project
The Moose River Hydroelectric Project is a single-unit run-of-river hydroelectric facility located near Lyonsdale, New York, and was developed by a private firm. The generating equipment...
Understanding Generator Static Excitation System
This paper explains some of the basic terms and features associated with a static excitation system (SES) to enable non-specialists to specify it according to their requirements. A simple...
Replacement of Computer Control at John Day Powerhouse
One of the first projects chosen by the Corps of Engineers for computer control was the John Day Project on the Columbia River. John Day powerhouse was completed in 1971 and has 16 generators...
Distributed Control Applications for Utility Hydroelectric Plants
In 1984, Washington Water Power began a program to improve monitoring and control systems for hydroelectric plants. The control systems being improved with distributed control equipment...

This paper discusses the performance characteristics of the programmable logic controllers (PLC's) is based governor, particularly speed resolution and response times. The...
Considerations to Be Taken in the Design of Speed Increasers for Hydroturbine Service
The paper discusses the incorporation of a speed increaser specification that is primarily functional yet one that will address the cost, reliability, efficiency, and life requirements...
Hydro Turbine Submergence
The elevation of a hydro-electric turbine above or below tailwater is based on hydraulic model studies to determine the critical sigma, defined as the ratio of barometric pressure plus...
Computer Aided Design of Small Hydro Turbine?Phase II
Ateliers Bouvier have been expanding the use of its computer aided design (CAD) system during these last four years, and the aim of this paper is to present some additional aspects of...
Pit Turbines, an Economical Solution for Low Heads
The paper describes the experience with pit turbine design and construction at the 8 MW St. Cloud facility located on the Mississippi River in Minnesota. Major topics in the paper include...
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...
Harnessing the Allegheny: Four Low-Head Projects
The navigable portion of the river, extending northeast of Pittsburgh approximately sixty miles, contains eight lock and dam systems under the jurisdiction of the U.S. Army Corps of Engineers...
Knowledge-Based Expert System for the Real-Time Operation of Reservoir Systems
An efficient way to avoid the loss of valuable knowledge is to develop an expert system which incorporates hydrologic, hydraulic, system analysis, environmental, economical knowledge based...
