The Paerau Gorge Multipurpose Scheme
The Paerau Gorge Power Scheme is part of a multipurpose scheme supplying irrigation water and electricity to the Central Otago region of the South Island of New Zealand. This paper describes...
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...
Arch Dams for Small Hydroelectric Sites
Approximate formulas are developed for the design of small arch dams. These designs, although conservative, frequently allow for economies over other dam types. Considered are: an approximate...
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,...
Changing Stability Criteria: Effect on Older Dams
Many of the dams on the Georgia Power Company system were designed and constructed in the early 1900's. Changes that have occurred in stability criteria since construction...
Dynamic Analysis of Existing Tarbela Intake Towers
According to general practice at the time of the design, the pseudostatic method of applying earthquake loading was used. The basic acceleration was 0. 1g. A post-construction seismological...
Rapid Filling of Reservoirs
The rate of filling a reservoir, particularly for the first time, is governed by various factors. While economic considerations may favor rapid filling of reservoir to operational levels,...
An Overview of Hoover Dam Tunnel Spillway Damage
The Hoover Dam tunnel spillways have provided the Bureau of Reclamation hydraulic laboratories with new and continued opportunities for applied research. During the peak years of the Boulder...
Safety of Dams Activities in the Bureau of Reclamation Lower Colorado Region
In the Lower Colorado Region of the Bureau of Reclamation (BuRec), there are presently eight BuRec dams and one Bureau of Indian Affairs dam being modified or studied for modification...
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...
Preventing Fish Mortality at a Large Pumped Storage Plant
A field study program was initiated at the Truman Project to obtain a better understanding of which fish species in the tailrace area would be most susceptible to turbine passage, determine...
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...
