Calaveras Pipeline Hydroelectric Project
The Calaveras Public Utility District (San Andreas, California) has a pipeline connecting its water treatment plant to the San Andreas Reservoir. By reducing the flow rate in the system...
Design and Application of an Open-Loop Control System for Run of River Sites
This paper compares an open loop control system for variable geometry turbines to a closed loop system for fixed geometry turbines. The control systems were designed to operate three submersible...
Low Head Hydroelectric Development on Madera Canal
The Madera-Chowchilla Power Authority with cooperation from the U. S. Bureau of Reclamation has been successful in the development of four hydroelectric plants at five head drops on the...
North Fork Hydro Electric Power Station
Lake Hemet Municipal Water District has recently installed a hydro power station capable of producing approximately 200 KW of power during years of normal flow and 600 KW during periods...
Hydropower on the Arkansas?A Non-Federal Development
In 1980, Arkansas Electric Cooperative Corporation (AECC) filed preliminary permit applications with the Federal Energy Regulatory Commission for developing the hydropower potential at...
Turbine Efficiency Loss Associated with Draft Tube Aeration
Draft tube aeration is one method for improving the dissolved oxygen content of hydroelectric discharges. A simple analytical procedure is presented for estimating the loss in turbine...
Analysis of Slow Speed vs. High Speed Generation
This paper presents a discussion of the relative merits of each alternative, with emphasis placed on experience gained from projects recently completed. The discussion considers such factors...
The Pacific Northwest Hydropower Data Base Study
The Hydropower Data Base is presently a functional tool for evaluating hydropower in the Northwest. It is a complete system which has been implemented using a variety of crosschecks and...
Friant Power Project: Design and Construction?Non-Federal Power at a Reclamation Facility
Friant Dam, Millerton Reservoir, provides the principal water supply for the Friant Division Central Valley Project of the U. S. Bureau of Reclamation (Bureau). The dam is a 319-foot high...
Economic Evaluation of Alternative Electric Power Developments
A hydroelectric-dominated power system and a thermal-dominated system represent different ways of meeting total electric demand, but with materially different cash flow patterns. This...
Control System Design Considerations for Small Hydro Projects
This paper deals with the philosophy that must be embraced when specifying a fast track small hydro project. The major areas discussed are: the role of control systems in the context of...
Electrical Design of Small Hydro Plants
Major aspects of electrical design criteria for small hydro power plants used in co-generation schemes are: turbine control, generator and excitation equipment selection, protection relaying,...
Modernization of Existing Hydroelectric Power Stations in Conjunction with Conversion to Automatic Operation
The easiest and, in the long run, the least expensive method in most cases is the installation of an electronic turbine governor that is not only easy to incorporate in the power station...
Performance Consideration for Selecting a Static Excitation System
Many hydropower plants today are being upgraded with new static exciter/regulator systems to replace the old existing rotary exciters. One type of system is the semi-inverting system where...
Application of an Integrated Numerical System for the Modernization of Hydro Turbines
The modules of an integrated numerical system for the new design and replacement of hydro power plant components are described and some examples of application are shown. The main modules...
Uprating Francis Turbines Provides Additional Energy
The use of existing powerhouse, penstocks, dams and unit configuration, all provide for a quick cost effective method to increase output from an existing turbine installation. This paper...
Run-of-River Controller for Hydro Plants
New York State Electric and Gas Corporation has installed programmable run-of-river (ROR) controllers at five of their plants. Each of these plants has either two or three units with installed...
Fish Screens for Hydropower Developments
The paper reviews five screening systems that are now being used at hydropower developments. The screen types discussed have a demonstrated ability to meet agency fish screening criteria....
Real Time Information Systems for Improved Port Operations
The technology to make appropriate measurements and to forecast conditions for short intervals is available today. Simple collection, analysis and dissemination systems are within the...
Capacity Planning of Decentralized Small-Scale Hydro Power Plants
Some simple and efficient models are proposed to determine the optimal capacity and the expected energy generation of a decentralized small-scale hydro plant. Both the supply of an isolated...
