Fire Protection at the Grand Coulee Hydro Project
In the fall of 1980 a rupture of one of the Project's 525kV transmission cables occurred and created a fire. Power from three Third Powerplant 700MW units was interrupted,...
Competitive Model Testing for Replacement Runners at the Wells Hydroelectric Project
The Wells Hydroelectric Project, located on the Columbia River, contains ten Kaplan-type turbines, each rated at 123,000 HP (91,720 kW) at a net head of 64. 9 ft. (19. 8m). The plant has...
Prototype Experience With Acoustic Flowmeters
The acoustic (ultrasonic) flowmeter offers many advantages over other methods for measuring discharge in penstocks for turbine performance tests. It is nonintrusive, inexpensive and may...
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,...
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...
Sewage Plant Engineered for Value
The Camden County (NJ) Municipal Utilities Authority was formed in 1972 to cope with suburban growth that had overloaded 34 primary treatment plants. By the early 1990s, the Authority...
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...
