Undeveloped Hydropower Resource Potential
The public hearings conducted as part of the National Energy Strategy produced testimony that concluded that the potential for development of hydropower was not well defined. As a result,...

Small Hydro Site Ranking, Cost Methodology and Program
The user-friendly micro-computer program SHYDRO for costing small hydro has been prepared for the government of Canada and is available in the public domain. SHYDRO was initially applied...

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...

Computer Modeling of Reservoir Sedimentation and Sluicing
A recently developed computer program which simulates the evolution, growth, and movement of a submerged delta in reservoirs was tested for Spencer Dam and Reservoir in Nebraska. The code,...

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...

Calculation of Three-Dimensional Turbulent Flow in Francis Turbine Runner
A numerical scheme, based on MacCormack's predictor-corrector explicit finite volume method, for solving three-dimensional weakly compressible inviscid, laminar, and turbulent...

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...

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...

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...

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...

Validation Studies on Indexed Sequential Modeling for the Colorado River Basin
A method called indexed sequential modeling (ISM) has been developed by the Western Area Power Administration to estimate reliable levels of project dependable power capacity (PDC) and...

Operation of Hydropower Plants Considering Daily Streamflows
Operation of hydropower plants is a sequential decision process often modeled as a dynamic programming problem. Typically, such formulations consider monthly stages assuming that monthly...

Consideration of Sedimentation on Hydropower Projects
Experience gained by analysis of a number of hydropower projects throughout the world leads to the conclusion that it is necessary to consider sediment related aspects in the design and...

Seismic Analysis of the Bonneville 1st Powerhouse
The Bonneville 1st powerhouse monoliths were constructed during the period of 1938 to 1942 and were designed against seismic loads using the old lateral coefficient method. The Corps of...

Uplift Reduction Using Drains
Uplift in cracks and in rock-concrete interface plays a crucial role in dam stability. Drains can be designed to intersect these cracks to reduce uplift. This paper explains how the effectiveness...

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...
