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...

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...

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...

Hydrologic Design Methodologies for Small-Scale Hydro at Ungauged Sites
IMP is a microcomputer package for evaluating small-scale hydroelectric power sites in British Columbia. With IMP it should be possible for an experienced hydroelectric engineer to make...

Estimating Streamflow Characteristics for Micro-hydro Sites in Northwestern Oregon
Assessing hydropower potential requires knowledge of the streamflow characteristics at prospective sites. Gaging stations are often unavailable. A method for estimating streamflow characteristics...

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...

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...

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...

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...

Flow Calculation in a Francis Runner
The flow through a Francis runner has been analysed theoretically. The flow calculations have been carried out by use of an inviscid 3D computational method solving the Euler-Equations....

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....
