Optimal Real-Time Control of Hydroelectric Power Plant Using Dynamic Programming
In this paper, an approach of optimal real-time control of hydroelectric power plant operations is presented. The methodology is based on a dynamic programming technique where the original...

Hand Held Powerhouse Control Console or Portable Data Terminal
The Portable Data Terminal (PDT) is a very small light weight hand held computer terminal that communicates with the control system computer by radio. An operator monitors power plant...

A New Power Invention
Hydropower is the most natural form of energy generated in the World. It allows us to make use of our natural resources without pollution. It harnesses the basic fundamentals of nature...

Optimising Electric Power From a Small Scale Hydro Plant
The paper summarizes new development in electrical power generation from small scale hydro prime movers. It describes various methods of power generation such as CSCF (Constant speed constant...

Ferroresonance & the Snettisham Hydroelectric Project
Key system features of the Snettisham power plant in Alaska will be highlighted along with a discussion of the operational problems encountered due to a ferroresonant condition. The project...

Voltage Regulator Influence on Generator System Stability
During initial startup of a generator system, it is not uncommon to witness generator voltage instability. Most of the time, the solution is reduced to returning the stability control...

Dam Safety Hydrologic and Seismic Evaluation of TVA'S Beech Dam
Beech Dam is part of the Beech River watershed resource development located in Decatur and Henderson counties in west Tennessee. The development consists of eight dams and approximately...

Satellite Imagery Refines PMF Determination
This paper focuses on electromagnetic energy sensors, and describes how they are being used to determine the Probable Maximum Flood (PMF) for a drainage basin in Michigan. Remote sensing...

Columbia River System Operation Review
For many years hydroelectric power has been a surplus commodity in the Pacific Northwest. However, this picture has been changing rapidly in recent years. Increasing pressures for use...

An Improved Incremental Economic Dispatch Method for Hydroelectric Generators with Nonconvex Energy Production Cost Curves
The Bureau of Reclamation (Reclamation) has undertaken a program to improve water resource management at its hydroelectric powerplants. One feature of the resource optimization program...

Risk Analysis Applications for Dam Safety
Dam safety modifications are intended either to reduce the likelihood of the adverse consequences of dam failure or the magnitude of adverse consequences. For instance, widening a spillway...

Unique Design Used for Collapsible Gate
The collapsible gate on the Wausau Dam is unique; there is only one known that is similar in design. The collapsible gate, which looks like an inverted V, was designed by Mead and Hunt...

Dardanelle Turbines
The Dardanelle turbines located at river mile 205.5 of the McClellan-Kerr Arkansas River Navigation System, are experiencing an unusual amount of wear in the blade trunnion bushings. Oil...

Rocky Mountain Pump-Turbines and Related Mechanical Equipment
The Rocky Mountain powerplant will have three reversible, single stage, vertical shaft pump-turbine units, each having a maximum output of 321 MW generating and a maximum pumping capacity...

Decision Support for Colorado River Operations
The United States Bureau of Reclamation (Reclamation) uses a simulation model known as the 24-month Study Model for planning monthly and seasonal operations for the Colorado River Basin....

Automated Lysimeter for Irrigation and Drainage Control
Knowledge of crop evapotranspiration (ET_c), the combined process of evaporation and plant transpiration, is important in agriculture for scheduling...

Use of Lysimetric Measurements for Designing Major Irrigation Systems in the USSR
The bioclimatic method for calculation of crop water requirements has been widely used in the USSR in recent years. The author has analyzed the results of its application for designing...

Lysimetric Monitoring for Operation of Irrigation Systems in the USSR
The author suggests a new method for operational control of irrigation regimes which is based on monitoring of a number of critical parameters related to the yield potentials of crops....

Prefabricated Weighing Lysimeter for Remote Research Stations
After designing and constructing several precision scale system weighing lysimeters in Southern Europe and the Middle East, the need arose for a prefabricated 'turn-key'...

Herbicides in Streams: Midwestern United States
Results from a 2-year study of 149 streams geographically distributed across the corn-producing region of 10 midwestern States show that detectable concentrations of herbicides persist...
