A Make/Buy Decision Analysis and Its Computer Program for Optimization of Cogeneration Plant Operation at Naval Submarine Base, New London, Connecticut

摘要

This report illustrates that cogeneration plant operation can be optimized through the use of a hand-held programmable calculator. The cogeneration system consisting of four high-pressure steam-generating units and three turbine generators at U.S. Naval Submarine Base, New London, CT is analyzed. A computer program written for use on a TI-59 programmable calculator is therefore developed to provide the personnel of the power plant a rapid determination of the optimum operating settings for the turbine/generator sets at any given time. Economic figures are presented to emphasize that the implementation of this program would result in significant improvements in economics and efficiency of the cogeneration process as the fuel price is expected to increase more rapidly than the utility rate. Although this computer program is initially developed for the application at SUBASE, New London, CT, its applicability to other similar cogeneration systems can be achieved by simple modification of the site-specific, sub-routine functions.
