Rehabilitation of a Pump/Turbine
Between 1964 and 1968, eight 212 in pump discharge diameter Baldwin-Lima-Hamilton vertical pump/turbines with Westinghouse motor/generators were installed in Philadelphia Electric Company's...
Uprating Francis Turbines Provides Additional Energy
The use of existing powerhouse, penstocks, dams and unit configuration, all provide for a quick cost effective method to increase output from an existing turbine installation. This paper...
Uprating Hydro Turbines and Generators
Various engineering evaluations of the turbine and generator components are required when considering uprating units. Often, certain turbine and generator components have to be redesigned...
Assessment of Probable Fishery Impacts of Hydroelectric Development at Lock and Dam No. 26 (Replacement), Mississippi River
Early coordination with affected Federal and state agencies allowed completion of an Environmental Assessment for a hydroelectric plant proposed for Lock and Dam No. 26 (Replacement)....
Galt Energy's Inverted Siphon System
Galt Energy Systems' involvement with attempting to standardize the civil component began with studies at small remote sites in Northern Ontario. The system design evolved...

Generic Power System Stabilizer Design
The object of this paper is to describe the design considerations of a microprocessor based power system stabilizer operating through excitation control as applied to a multi-unit pumped...
Increasing Hydropower Operating Efficiency
A method is described for determining the most efficient use of hydro units in a multiple unit hydro plant. In a multi-unit plant enough flexibility exists to load a chosen set of units...
Transient Analysis of Variable Geometry Turbines
An interactive general purpose hydraulic transient computer simulation procedure is presented which is capable of performing transient analysis of variable geometry turbine installations....
Simplified Model for Micro-Hydro Feasibility
A computer model was developed for evaluating the preliminary hydraulic and economic feasibility of potential micro-hydro development sites. Among the main objectives of the model are...
LRFD Format for Transmission Structures
The structural design of high voltage electric transmission lines in the US is usually governed by the National Electrical Safety Code (NESC). A simple reliability-based Load and Resistance...

Guidelines for structural loads on electrical transmission structures were prepared by the American Society of Civil Engineers' Committee on Electrical Transmission Structures....
A Field Study of Wind-Induced Conductor Loads
A 161 kV steel pole line in Omaha, Nebraska, is instrumented to provide conductor load field data due to climatic events. Various transducers and monitoring equipment used for data acquisition...
Design of Drilled Piers Subjected to High Overturning Moments
The results are presented of a research study directed at improving the state-of-practice, and resulting foundation economy, in the design of laterally loaded drilled pier foundations...
Strength Data Base for LRFD of Transmission Lines
Reliability-Based Load and Resistance Factor Design (LRFD) has been proposed as a desirable alternative or a complement to the National Electrical Safety Code (NESC) for the structural...
Adfreeze Strength of Ice to Steel Pipe Piles as a Function of Temperature
A study was initiated to determine the adfreeze bond strength between steel pipe piles and freshwater ice as a function of temperature. Tests were conducted at an average strain rate of...
Iceberg Impact Load on a Gravity Based Structure
The mechanics of the eccentric collision of an iceberg against a fixed, rigid, gravity based structure are discussed. A closed form solution is derived for the case of infinite friction...
A Self-Refrigerated Gravel Pad Foundation for Large Thermal Loads
Design criteria for a proposed power plant at Thule Air Force Base, Greenland, involved both large thermal loads from the diesel engines and large static loads from an eight foot thick...
