GIS Applications to the Water Resources Development Program of the U.S. Army Corps of Engineers
The ability that a Geographic Information System (GIS) offers to quickly reference multiple data sets to an overall base map and to one another provides the potential opportunity to greatly...
Hydrometric Networks Serving Hydropower Needs
The Water Resources Branch is the national agency that collects, interprets and disseminates standardized surface water quantity and sediment data and information in Canada. The Branch...
New Clues to PMP
Great changes have occurred in meterology in the last two decades. Formerly, weather data were available for forecasting and climatological analyses only at points - at weather stations....
Efficiency Monitoring Yields Large Revenue Gains
This paper presents a Washington Water Power Company program to increase hydroelectric plant operations' efficiency. This increase is due to improved flow, head, and megawatt...
Understanding Generator Static Excitation System
This paper explains some of the basic terms and features associated with a static excitation system (SES) to enable non-specialists to specify it according to their requirements. A simple...
Design Data of Kaplan and Bulb Turbine Units
Some basic statistical data covering geometrical and energy parameters for Kaplan and bulb turbine units are presented. These data are further compared as specific rations for both units,...
Implementation of a General Purpose Site Monitoring Network
STS Hydropower owns and operates several hydroelectric plants distributed throughout the United States. These plants, equipped with intelligent controllers, have been remotely monitored...
Evaluating Uplift Pressures for Concrete Gravity Dams
An approach for evaluating uplift and dam foundation conditions, which resulted from the initial phases of an Electric Power Research Institute (EPRI) study is presented. An earlier study...
Digital Data Acquisition and Performance Testing of Hydroelectric Equipment
The U.S. Army Corps of Engineers Hydroelectric Design Center has elected to use digital data acquisition methods when conducting performance tests of hydroelectric units. Transducers have...
Real-Time Project Tracking
Too often project tracking is based on a job costing program which charges costs to the project based upon invoices from vendors and payrolls of employees. The information obtained from...
Integrated Automation for Site Work
Technologically, computer integration can be built around four component systems; (a) a computer system to maintain unified data and control real-time operations, (b) a metrology system...
Real-time Monitoring of Heavy Equipment in Open Pit Mines
This paper reports on a system with local intelligence to interpret on-board signals. Existing sensors, pressure switches, warning lights, relays, and on-board monitoring systems provide...
Eliminating Bias in Construction Schedules to Measure Time
Schedules developed for use in managing the construction process which are accurate for that use are not necessarily sufficiently accurate to measure and evaluate delays and changes to...
Integrating Voice Recognition Systems with the Collection of Project Control Data
The Construction Industry in the 1990's will be dominated by emphasis on Productivity, Competitiveness and Innovation. Success or failure in these areas lies in one word, Technology, and...
Actual Vs. Expected Performance of Small Hydro Projects
This paper presents the results of several case studies of small hydro projects that compare the expected performance with the actual performance as measured in terms of energy generation....
Small Hydro Analysis and Reporting Program
The Ontario Ministry of Energy initiated a project to develop an analysis program based upon metric measures and Canadian costs. The Ministry of Energy of the Province of Ontario has been...
Cumulative Impact Assessment: Application of a Methodology
The authors expanded upon the Federal Energy Regulatory Commission's (FERC) Cluster Impact Assessment Procedure (CIAP) to provide a practical methodology for assessing potential...
Rain Data Telemetry for Operation of a Hydro-Reservoir
The Collywobbles hydro-electric station operates 42MW with very little river storage. Raindata is collected from 11 gauges distributed in the 5000 km**2 catchment and telemetered to a...
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...
Generators with Shaft Mounted Turbine Runners
Water turbine runners mounted on an extended generator shaft are often specified to eliminate turbine bearings and the flexible shaft coupling. Two bearing single shaft turbine generator...
