Probabilistic Capacity Value of Nonfirm Hydro Energy
Electric utilities with a predominant mix of hydro generation traditionally apply Energy Planning criteria rather than Capacity Planning criteria in developing their generation resources...
A Case Study: Relicensing of Pensacola Hydropower Project
The current license for the Pensacola Hydropower Project (orginally licensed in 1939) will expire in 1988. The relicensing process for the project currently is underway. During the consultation...
Studies of Fish Protection Methods at Hydroelectric Plants
Five largely untested but economical fish-protection systems were tested at sites throughout North America. The process of selecting laboratory and field test sites was completed at the...
Design of Siphon Penstocks for Low Head Hydros
Siphon penstocks have been designed and constructed at Jim Falls and Winter, Wisconsin at existing dams. Both hydropower projects are located on the Chippewa River. The design of these...
Turbine Intake Modification for Fish Passage
This paper describes one solution the U. S. Army Corps of Engineers has found to improve juvenile fish guidance at Bonneville Second Powerhouse on the Columbia River. Juvenile fish passage...
Frazil Ice Control Using Electromechanical Cibrators and Ice-Resistant Coatings
Two methods, using electromechanical vibrators and ice-resistant coatings, were studied in a small-scale test conducted at the U. S. Army Cold Regions Research and Engineering Laboratory...
Design and Operation of a Differential Surge Tank
The differential type of surge tank is more effective in operation than the simple type because it reacts more quickly to load changes of all sizes. The differential tank is also usually...
Performance Evaluation of Rim-Drive Turbines
This paper will provide a performance evaluation of the technical and economic advantages and disadvantages of the rim-drive turbine after more than one year of operation. Technical aspects...
Generators with Shaft Mounted Turbine Runners
Water turbine runners mounted on an extended generator shaft are often specified to eliminate turbine bearings and the flexible shaft coupling. Two bearing single shaft turbine generator...
The Value of Model Testing in Computer Aided Pump and Turbine Design
This paper discusses the importance of model testing for development and sharpening of interpretive techniques through which computational codes can be effectively used for the design...
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....
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...
Turbine Efficiency Monitoring Utilizing Ultrasonic Flowrate Measurement
On-line turbine efficiency measurement can be achieved by ultrasonic flowrate measurement and state-of-the-art data acquisition techniques. A field performance test program conducted at...
Field Testing: Producing Complete Test Results on Site, A Realistic Objective
Modern technologies and instruments have had an influence in nearly every field imaginable. At Hydro-Quebec, the last ten years have brought about a complete transformation in the way...
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...
Programmable mMicroprocessors in Local Control of Hydro Power Plants
The main purpose of the control equipment is to provide the generator with means for operation of the power station equipment. There is a need for status information on the generating...
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...
Influence of Surface Finish on Thrust Bearing Life
The original pivoted pad thrust bearing installed and fitted at the Holtwood Power Station in 1912 by A. Kingsbury has been operating continuously since that time without any difficulty....
Accelerated Life Testing of Generator Coils
This paper presents a step-by-step procedure for doing a 400 hour, 60 Hz, 90 degree C accelerated life test on generator coils. Test procedure is as follows: 1. Initial coil examination...
