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...

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...

Standard Safety and Control Concept for Double Regulated Small and Medium Hydro Turbines
The paper proposes a standard control concept for double regulated small and medium hydro turbines. The concept is based on minimum protection requirements for safe and reliable quick...

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...

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...

Penstock Rehabilitation
The deterioration of aging penstocks is a common problem at many existing hydroelectric plants. A comprehensive understanding of the physical condition and functional limitations of an...

Evaluation of Turbine Intake Velocity Criteria
The paper addresses the effect of intake flow distribution on turbine performance at low-head projects. Field and model test data are used to raise the question of whether typical turbine...

A Case Study, Large Versus Small
This paper will review the hydraulic comparisons between the Lock and Dam No. 13 Hydropower Project, a 33-MW, low-head generating station near Fort Smith, Arkansas, and the Murray Hydroelectric...

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....

Turbines and Pump Turbines for Ultra High Heads
The paper describes the turbine development in Norway as background for high head turbine technology and shows a typical Norwegian high head Francis as an example. High head reversible...
