Load/Resource Matching for Period-of-Record Computer Simulation
The Southwestern Power Administration (Southwestern), an agency of the Department of Energy, is responsible for marketing the power and energy produced at Federal hydroelectric power projects...
Decision Rules for Reservoir Releases
One of the problems faced with computer modeling of a multi-reservoir, hydro-power system is making decisions on how releases will be made. Reservoirs many times have multiple demands...
The Wisconsin River System Operations Model: WIRSOM
The passage of the Electric Consumers Protection Act of 1986 requires the Federal Energy Regulatory Commission to give equal consideration to non-power as well as power values in hydroelectric...
A Flow Forecasting System for Hydro Power
The flow forecasting system comprises a network of meteorological stations, a weather forecasting model, and a watershed hydrologic model, implemented in a microcomputer. The meteorological...
Development of a New Hydraulic Design Tool for Spiral Casing/Distributor Geometry
A novel computational model has been developed to predict highly complex turbulent flow in a combined spiral casing/distributor geometry. Validation of the computational model against...
Design of Powerhouse Spiral Case Considering Three-Dimensional Action
A commonly used approach of designing semi-spiral cases for Kaplan turbine installation using two-dimensional frames becomes unsuitable for large diameter turbines and/or high heads. The...
Deflector Synchronizing and Governing
This paper is a survey of deflector control speed govern impulse turbines for synchronization to a grid, and for isolated operation. There are several advantages to deflector control versus...
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...
Electrical Design Survey
In North America, a mini hydro project consists primarily of the civil works which routes water to the turbine generator and the electrical hardware necessary to interface it with a utility....
A Hydroelectric Plant Operator's Assistant
This paper describes a PC based application designed to assist in the process of enhancing the performance of multi-unit hydroprojects. Optimization considerations, uses of the Operator's...
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...
Economic Impact of Reduced High-Voltage Equipment Life
In May, 1989, the Western Area Power Administration and the Bureau of Reclamation published a report entitled Replacements: Units, Service Lives, Factors. This report showed that equipment...
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...
Design Considerations for Radial Key Retrofit
A practise that is becoming more and more common is to retrofit hydro-electric generators with Radial Key Systems. There are significant design considerations that must be made to ensure...
Varying Generator Excitation to Control Draft Tube Surge
