Optimisation of Bulb and Kaplan Turbine Runners
The paper presents a brief survey of the theoretical method used so far at Turboinstitut Ljubljana for axial runner design and analysis. Theoretically optimised runner is later experimentally...

Calculation of Blade Trunnion Reactions in Kaplan Turbines
A computer program is presented to calculate the blade trunnion reactions in Kaplan turbines. The program calculates the trunnion reactions for operation of the turbine at steady state...

Hydro Research and Plant Renewal
Obtaining extra energy or output from existing plants is the current topic when the question of refurbishing older turbine installation arises or when plant operating conditions can be...

Rehabilitation of a High Specific Speed Francis Turbine
An upgrade of two (2) 4. 06 meter diameter high specific speed Francis turbines is now in progress. These machines were originally installed by Allis-Chalmers in the 1920's...

The Cougar Project?Turbine Runner Replacement
The Cougar turbine runners have been subjected to a substantial amount of cavitation damage which has required repair by welding. The continued welding repair has subsequently resulted...

Economic Evaluation of Replacement Turbine Runner Bids
Many owners of hydro facilities are investigating increasing plant capacity and output by upgrading existing hydraulic turbines. Typically, the owner will conduct a detailed feasibility...

Potential for Upgrading the Robert Moses Niagara Power Plant
This paper summarizes the feasibility of increasing the generating capacity of the Robert Moses Niagara Power Plant by replacing the turbine runners, upgrading the generators, and replacing...

Major Hydraulic Turbine Operation and Maintenance Problems Experienced by the Corps of Engineers
The U. S. Army Corps of Engineers is the largest owner/operator of hydroelectric power generating facilities in the United States with 344 generating units, having an installed capacity...

Synopsis of Harry S. Truman Turbine Repair
The Harry S. Truman Powerplant was designed and constructed under the supervision of the U. S. Army Corps of Engineers and is located on the Osage River near Warsaw, Missouri. During 1981...

An Analysis of Cavitation Damage in a Francis Turbine Operating Under Small Opening Condition
In this paper some new formulae are derived to estimate the pressure and the relative velocities in the crown and the band regions of the Francis turbine runner operating under any gate...

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...

Racine?5 Years of Successful Operating Experience with the World's Largest Bulb Turbines
In September 1982 two bulb turbine generating sets with a runner diameter of 7700 mm and a generator rating of 25 MVA were put into commercial operation at the Racine dam on the Ohio river....

Development of Three Systems Operated Rev. Pump Turbine
In order to represent the development of reversible, single stage pump turbines in Yugoslavia, the three systems operated pump turbine (3SRPT) of the fourth unit of Moste hydro power plant,...

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...

Independent Turbine Testing and Research
The St. Anthony Falls Hydraulic Laboratory (SAFHL) is presently upgrading their Turbine Test Facility. Completion of the upgrade, including checkout tests, is scheduled for Fall 1987....

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...

Experimental Investigation of the Cross Flow Turbine
A laboratory model of the Cross Flow Turbine was investigated in the Hydraulics laboratory of Colorado State University. Because of the successful use of this turbine in the developing...

Digital Control of 180MW Francis Turbines: Controller Design, Simulation, and Operational Results
The features of a new hydro-power station are outlined as are some specifications that the customer required of a digital controller. Both hardware and software aspects of this recently...

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...

Large Low-Speed Generators with Skewed Supporting Parts
During the past decade, the demand for hydro-generators has been for increasingly high ratings, up to the present maximum of about 800 MVA. These low-speed machines have rotor diameters...
