Purchasing a quality Supervisory Control and Data Acquisition (SCADA) or Energy Control System (ECS) at a reasonable price for a particular installation can be a challenging undertaking....

Generator/Motors and Adjustable-Speed Drives for Waddell Pumped-Storage Plant
This paper describes the pumping and generating units and associated electrical equipment planned for Waddell Pumped-Storage Plant. Waddell Pumped-Storage Plant is to be located near Phoenix,...

Kaplan Blade Angle Controller
This paper describes a recently developed computerized Kaplan blade angle controller that is capable of improving turbine performance. Model Tests or Index Tests produce the Three-D-Cam...

The Design and Operating Experience of a Multiplexer Application in Conventional Hydro Powerhouse Control
The design of the Bonneville Second Powerhouse control system presented an opportunity to replace conventional cables with a multiplexer system that would provide a two-way data communication...

Capabilities of Automated Control System Employing Advanced Programmable Controllers
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...

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...

Hydropower Development at North Hartland Lake, Vermont
The purpose of this paper is to give a short history of the first hydropower development by non-Federal interests at a Corps of Engineers flood control dam and reservoir within the jurisdiction...

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...

Building Bridges Faster
Guidelines are presented that tell how to write a contract that will lead to radical reductions in the time to build or rebuild a bridge. The article covers how to write an incentive/disincentive...

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...
