Systems Analysis for Fisheries Protection and Mitigation at Corps of Engineers Columbia River Dams
Pacific Northwest anadromous salmon and steelhead that migrate to and from the ocean are greatly affected by the numerous Columbia and Snake River dams they have to pass, first downstream...

Power System Study to Determine Hydro Benefits
This paper discusses evaluation methodologies used by Stone & Webster to determine the power benefits for six potential hydropower projects at existing U. S. Army Corps of Engineers...

Reliable Operation of Hydro-Thermal Power Systems
The demonstrated model allows planners to account for both operating and shortage costs, subject to a constraint on the system failure rate. In addition, the optimal long-term operation...

Pumped Storage and Power System Operations
The 2100 megawatt Bath County pumped storage power station began commercial operation in December 1985 as a jointly-owned project of Virginia Electric and Power Company (Virginia Power)...

Operational Flexibility?A Precious Commodity
This discussion is about Operational Flexibility, as it applies to the generating resources of a large electricity system. The author discusses the situation at Ontario Hydro, operationally...

Determination of Values of Project Storage for Hydropower Scheduling
The Columbia River is characterized by multiple and sometimes conflicting uses, and its basin extends over many political jurisdictions. To balance pluralistic needs and authorities with...

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...

30 More Megawatts at the Don Pedro Project, Calif.
A unique and cost effective concept for installing an additional hydroelectric generating unit to an existing project in a very confined location is presented. The concept also allows...

Hydro Combine Option for Lakhwar Project
A new concept of providing a power house cavity inside the traditional gravity dam section has been explored. Preliminary investigations indicate that taking into account all the relevant...

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...

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....

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...

Fire Protection at the Grand Coulee Hydro Project
In the fall of 1980 a rupture of one of the Project's 525kV transmission cables occurred and created a fire. Power from three Third Powerplant 700MW units was interrupted,...
