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,...

Application of Computer Aided Design and Analysis Tools for Upgrading Existing Power Plant Equipment
This paper presents examples where state-of-the-art computer aided design and analysis techniques have been applied to upgrade hydraulic performance and structural reliability of existing...

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...

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...

HydroMAX; Computerized Hydropower Scheduling
The New England Power Exchange (NEPEX) is currently using the HydroMAX Program to schedule daily hydropower operations for the 17 stations in the 11,250 square mile Connecticut River Basin....

Interactive Simulation of Hydropower Systems
This paper describes a new educational technology that has proven extremely effective in introducing both technical and lay persons to the operational principles, management alternatives,...

Generic Power System Stabilizer Design
The object of this paper is to describe the design considerations of a microprocessor based power system stabilizer operating through excitation control as applied to a multi-unit pumped...

Optimal Dispatch of Hydroelectric Systems
This paper presents a reliable and computationally efficient method for solving the optimal hydro dispatch problem. Moreover, this method guarantees a true optimal solution when the units'...

Increasing Hydropower Operating Efficiency
A method is described for determining the most efficient use of hydro units in a multiple unit hydro plant. In a multi-unit plant enough flexibility exists to load a chosen set of units...

Quantifying the Maximum Capability of Hydroplants
A procedure was developed to quantify the maximum hydropower capability. This procedure basically consists of two steps: dividing the total available water into weekday and weekend components;...

Hydro System Enhancement: TVA's Comprehensive Hydropower Program
The Tennessee Valley Authority's Comprehensive Hydropower Program is systematically identifying opportunities for increasing hydroelectric generation in five areas: small...

HYPOS?Hourly System Hydropower Scheduling
HYPOS (Hydro Power Scheduling) is a modification of the program HYPO as presented at Waterpower 81. HYPOS is an interactive system which allows schedulers to assign hourly power generation...
