This paper details Voith Hydro's range of experience in the use of Programmable Logic Controllers (P. L. C. 's) in the automation of new hydro electric sites....
Integrated Automatic Hydroelectric Plant Control
The increased acceptance and employment of microcomputers to control specific functions in small hydroelectric plants has led to computerized integrated total control of hydropower generation....
Voltage Versus Var/Power Factor Regulation on Hydro Generators
When paralleled to the utility bus, synchronous generators can be controlled using either terminal voltage or var/power factor regulation. Selection is dependent upon the size of the generator...
Control and Tests of Tims Ford Induction Generator
This paper will discuss the electrical control scheme and commissioning tests developed for a small induction generator installed by the Tennessee Valley Authority (TVA) at its Tims Ford...
The Stanley Canyon Conduit Hydroelectric Project
The Stanley Canyon Hydroelectric Project is an excellent example of the maximum use of a natural resource. The project is a combined water supply and hydroelectric facility which received...
Upper Yellow River Projects and Longyangxia Station
The river stretch from Longyangxia to Qingtongxia, with a head drop of 1,465 m in a distance of 1,023 km (including backwater length of the Longyangxia Reservoir) is the focus of this...
Summer Falls High Head Kaplan Turbine Project
The Summer Falls Project is located on the Main Canal of the Grand Coulee Irrigation Project approximately eight miles south of Coulee City in Grant County, Washington. The power development...
Our Municipal Water System Has Power
Hydroelectric potential exists in the Boulder, Colorado municipal water system. Excess pressure is developed in the water system because the water originates in the Rocky Mountains, west...
Hydropower Goes Downtown
Beneath a busy street in Southern California seems an unlikely location for a small hydroelectric generating plant. However, located just below El Segundo Boulevard in the town of El Segundo...
Planning, Design and Cost Estimates for RCC Dams
Engineers, planners, and officials of agencies responsible for developing water resource projects are confronted with preparing preliminary designs and cost estimates for dams. This paper...
Design of Seepage Control Systems for RCC Dams
As the reservoirs of the first generation of roller compacted concrete (RCC) dams have been filled, several have exhibited significant amounts of seepage, a fact that has been of concern...
Roller Compacted Concrete Mix Design for Pamo Dam
Pamo Dam is designed as a 265 foot (81M) high gravity dam that will be located on the Santa Isabel Creek in San Diego County, California. RCC volume will be approximately 491,000 cubic...
Quality Control/Inspection�Upper Stillwater Dam
Roller compacted concrete construction, or RCC, is a relatively new method of constructing concrete dams and involves placing and spreading no-slump concrete in horizontal layers and compacting...
Vibration Analysis Using a Parallel Lanczos Method
A parallel eigenvalue solution algorithm, based on the Lanczos method, has been developed, implemented on a Flexible Computer FLEX/32 multi-processor, and applied to an example structural...
Concurrent Nullspace Methods for Multibody Systems
This paper presents a new concurrent multiprocessing algorithm for simulating the dynamics of constrained multibody systems. The systems considered are quite general in nature; they may...
Structural Analysis and Parallel Computers
This paper discusses the implementation of a parallel program that performs a two dimensional rigid frame analysis on a NCUBE/7 hypercube multicomputer. The program was written in C and...
A Finite Element System for the CDC CYBER 205
This paper summarizes some of the special considerations required for finite element system development on the CDC CYBER 205. A means of constructing an efficient database is presented....
Finite Strip Method in a Parallel Computing Environment
The finite strip method has been used to model many systems in structural mechanics. The orthogonality of appropriately selected shape functions allows a continuous system to be effectively...
