Marketing Power in the Pacific Northwest
The marketing of power in the Pacific Northwest is a process intimately tied to the management of the Columbia River system. This paper describes the characteristics of the river and transmission...
Columbia River Treaty Perspectives
The Columbia River Treaty was signed in 1961 and ratified by the governments of Canada and the United States in 1964. The Treaty required British Columbia to construct three large storage...
Reservoir Regulation in the Monsoon Climate of Korea
An examination of reservoir regulation rules in light of uncertain estimates of river flow in the Han River Basin, Republic of Korea, shows that two strategies will improve total hydroelectric...
Multisite Hydrocomplex Optimization
A multisite complex is analysed in northern Quebec to decide the level of equipment needed that will supply firm energy at the best possible unitary price. Four possible sites were chosen...
Hydropower Development of China's Yangtze River
The Yangtze has eight times the hydro potential of the Columbia River basin, currently the largest developed hydro system in the world. In order to pursue economic development through...
Computer-Aided Operation of a Hydropower System
This paper outlines the development of a computer model which optimizes the operation of a regulated river system given certain constraints using an adaptive deterministic linear programming...
A Case Study of Hydropower Operation Based on Runoff Forecast
The intent of this paper is to outline a forecast approach developed to enable the operation of power storage projects, and to illustrate from employing the approach that overall system...
Hydrologic Dispatch Model for a Hydropower System
A hydrologic dispatch model was developed for an 11 plant, six reservoir hydroelectric system. The model incorporates load forecasting, system dispatching strategy, and database management...
DURAPLOT: A Flexible Approach to Hydropower Site Optimization
The U. S. Army Corps of Engineers, North Pacific Division Office has over the past six years performed reconnaissance and feasibility level hydropower studies at a variety of sites throughout...
The Use of Time Series Analysis to Estimate Flow Duration Curves to Assess Energy Potential for Low Head Hydro Redevelopment
The proposed hydroelectric site location has a low head potential making discharge the primary energy production component. A flow duration curve (FDC) study was commenced to generate...
Using Fall Streamflows as Predictors of Spring Runoff at the Dalles, Oregon
The Northwest hydropower system is characterized by a drawdown season when normally full reservoirs are drafted to meet firm obligated loads, and a refill season in which the reservoirs...
Early Detection of Rotor Cracks?Monitoring & Methodology
This paper describes a diagnostic method for the early detection of shaft cracks on rotating machines. The method is based on interpretation of the lateral synchronous (1x) and twice per...
Variable Speed Generators in Hydro Applications
This paper discusses the investigation of the doubly-fed variable speed machine as a potential candidate to convert a varying input speed to a constant frequency, constant voltage output....
Characteristics of the Roesel Machine Used for Small Scale Hydro/Wind or Sea Wave Electric Power Generation and Storage
An electrical machine with property of synchronous as well as asynchronous characteristics and based on ceramic magnet programming technology by continuous printing of the desired number...
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...
Free-Rotor, River-Velocity Turbine
This paper discusses the development of a very simple and inexpensive underwater turbine which will extract power ranging from a fraction of a HP up to 20 HP from the velocity of the running...
Bureau of Reclamation Uprating Program
The Bureau of Reclamation is an agency of the Department of the Interior and was established in 1902 to oversee the development and conservation of the Nation's water resources...
Efficiency in Auxiliary Electrical Systems
In 1984, during the preliminary design for the proposed second powerhouse at the Corps of Engineers' McNary Dam on the Columbia River, the more recent improvements and techniques...
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,...
Integrated Automatic Hydroelectric Plant Control
The increased acceptance and employment of microcomputers to control specific functions in small hydroelectric plants has led to computerized integrated total control of hydropower generation....
