Electrical Design of Small Hydro Plants
Major aspects of electrical design criteria for small hydro power plants used in co-generation schemes are: turbine control, generator and excitation equipment selection, protection relaying,...
Specification Writing for Small Hydro-Generators
For small hydro projects, it is all too common for the spec writer to use a convenient off-shelf spec usually written for a much larger unit. Minor modifications (primarily ratings) are...
Conversion Experience at the Chief Joseph Dam Project
In August, 1983, Woodward Governor Company was awarded U. S. Army Corps of Engineers contract DACW67-83-C-0076 to convert ten existing Allis-Chalmers and six existing Woodward Governor...
Experiences During Overhaul of Hydroelectric Units
This paper describes some of the conditions found during major overhaul of main units at two hydroelectric power plants. Problems encountered and their solutions are described. The effects...
More Kilowatts with Less Investment
The paper discusses partial or complete modernization of hydraulic units and/or governing system as a means to increasing profitability. A combination of general and case history applications...
Practical Aspects of Repairing and Rewinding Hydro-Electric Generators
Often the general condition of the winding can be assessed and in some cases, corrective action can be taken to prolong the life of the winding. In other situations, the assessment may...
Performance Consideration for Selecting a Static Excitation System
Many hydropower plants today are being upgraded with new static exciter/regulator systems to replace the old existing rotary exciters. One type of system is the semi-inverting system where...
Infrastructure Development and Turbine Building
Aggressive development schedules which characterize many projects imply a degree of construction management know-how or alternatively, may say something about the state of the industry...
Importance of Public Consultation
Early consultation with governmental resource agencies as well as private environmental groups can mean the difference between early resolution of conflicts between developers and environmentalists...
Planning for Small-Scale Hydroelectric Development: A State Response
A 'surplus' of power in the Pacific Northwest region of the country has brought with it a declining interest in the generation of new electrical energy supplies....
Small Hydro Advocacy
The state public utilities commissions wield enormous power over the destiny of small hydro projects; power extending over rates, contract terms and dispute resolution. Yet developers...
Coordinating Engineering and Environmental Activities in Hydropower Development
This paper reviews the role of hydropower project personnel, particularly the interaction between project management, engineering, and environmental sciences staff in project planning...
Fish Screens for Hydropower Developments
The paper reviews five screening systems that are now being used at hydropower developments. The screen types discussed have a demonstrated ability to meet agency fish screening criteria....
Salmon Restoration: Blessing, Bane or Boondoggle?
The 'strategic' plans for the Atlantic Salmon Restoration Program were examined to determine what the strategy of the U. S. Fish and Wildlife Service is for this...
Hydropower Contract Conditions for Civil Engineering Works
Norwegian types of contract documents for hydropower construction work - especially the underground parts - have long had the reputation of being flexible as opposed to the traditionally...
Design and Construction of Paute Project, Ecuador
The Paute Project is a key element in Ecuador's program for developing a modern electric power system. When fully developed, it will consist of three separate developments:...
Efficient Small Hydroelectric Plant Operation
This paper presents a review of operating and maintenance alternatives for small scale hydroelectric plants. The cost of operating a hydro project is largely determined by decisions made...
Hydro Systems Evaluation on Personal Computers
The programs for selecting the equipment and determining the average annual energy have been separated from the detailed financial analysis. The BASIC language was selected for the first...
Steel Poles?Past, Present and Future
When using steel pole structures, construction possibilities are limitless. Of all the options available, tubular steel structures provide the most versatility for transmission line construction....
Special Pile Foundations for a Coastal Permafrost Site
The design of the plant's foundations had to address several challenging geotechnical conditions. These included (1) 'warm' (close to 32 degree F)...
