The Design of the Nanpil River Hydropower Project
In 1980, the State of Pohnpei (then spelled Ponape) asked the Pacific Ocean Division of the U. S. Army Corps of Engineers to investigate the feasibility of constructing a hydroelectric...
Field Observations of Cavitation Erosion in Hydraulic Turbines
Field surveys of the operational and design characteristics of 602 hydroturbines installed since 1950 and having a capacity in excess of 20 MW or a discharge diameter greater than 3 meters...
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...
Index Testing With a Data Acquisition and Control System
A computer controlled index test has been developed that can be used to optimize blade-gate relationships on adjustable blade (Kaplan) hydraulic turbines. This paper includes hardware...
