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...
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...
Optimal Operation of the Savannah River System
This paper presents an application of a stochastic control method to the real time operation of the Savannah river system which includes three reservoirs and is expected to meet energy...
The Role of Headwater Benefits in Hydropower Planning
Headwater benefits are the power benefits that accure to owners of downstream hydroelectric plants as a result of the operation of headwater improvements. The retention of water in upstream...
Dam Safety Emergency Action Plans?A TVA-State Responsibility
The Federal Guidelines for Dam Safety requires each dam owner to prepare and maintain emergency action plans (EAP) for each of structure. These plans are necessary (1) to identify problems...
Appropriate Design and Construction of Conduits for Small and Mini Hydropower
The success of smaller hydro schemes often lies in identifying feasible and economic waterway systems to develop relatively high heads between low intake weir and powerstation. This paper...
Rebuild of Ten Mile Intake Flume Structure for Electron Hydropower Project
In 1984 the Puget Sound Power and Light Company began a rebuild of what is popularly referred to as the 'world's crookedest railroad. ' The 'railroad'...
The Rehabilitation of Lake Harriet Dam
In 1984, the decision was made to rehabilitate the Lake Harriet Dam. The existing arch dam structure was encased with a rockfill buttress. The downstream buttress, which also acts as a...
Murray Hydro Project?Structural Design
This paper will summarize design criteria, parameters, methods of analysis, and other relevant data that were used in the design process of the structural features of the Murray powerhouse...
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...
Civil Design of Underground Hydro Power Projects
Various reasons exist for the development of underground schemes. Limited space at dam sites in deep and narrow river valleys makes it favourable to separate the power house from the dam...
Waterstop Technology?The Next Chapter
Water leakage through and around failed waterstops in concrete structures can cause serious flooding, damage to equipment, affect structural stability, and pose potential safety problems....
The Use of Polyurethane Grouts and Grout Tubes
Most polyurethane grouts used for seepage control are one-component, and water activated. They are prepolymers of a polyisocyanate with a polyol. Some of the polyurethane grouts use an...
Osoyoos Lake Control Structure
The new Osoyoos Lake Control Structure has been built on the Okanogan River at Oroville, Wa. The site is about 2 miles downstream from the outlet of Osoyoos Lake, and about 9 miles south...
Analysis of Hydraulic Transients for Design and Operation of Two Powerhouses in Series
The Dinkey Creek Project will be located in the southern Sierra Nevada mountains 40 miles north-east of Fresno, California, and will develop about 4000 ft of gross head with a maximum...
Mountain Jungle Intakes?Design and Model Study
Nine intakes of various sizes and designs supply water to the two high head power plants in the Sungai Piah Hydroelectric Development in Malaysia. The intakes are located on steep mountain...
Layout of a Powerhouse Adjacent to Lock and Dam Structures
An approach flow to a powerhouse intake adjoining existing lock and dam structures may cause a significant reduction in the efficiency of the powerhouse and give rise to an economically...
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...
Turbine Casing and Distributor Hydraulic Design
Interactive casing and distributor hydraulic design and flow analysis software has been developed and tested. Until now, its application is limited to radial distributor turbo-machines....
