Operational strategy for an industrial gas turbine cogeneration plant
by Koichi Ito, Ryohei Yokoyama
International Journal of Global Energy Issues (IJGEI), Vol. 7, No. 3/4, 1995

Abstract: A computer-aided advisory system is proposed which assists operators in operating an industrial gas turbine cogeneration plant rationally from the economic viewpoint. An optimization approach is adopted to acquire knowledge of the plant's operational strategy. The on/off and rated/part load status for each piece of constituent equipment is determined so as to minimize the hourly operational cost subject to the energy demand requirement. Various restrictions which must be satisfied in operation are incorporated simultaneously. The operational strategy by optimization is compared with operation, using data measured on several representative days. The operational status obtained for combinations of electricity and steam demands is illustrated by operational maps.
