概要

An advanced co-generation system (ACGS) was built at Waseda University. The ACGS consists of a gas turbine, a steam turbine, an ammonia absorption refrigerator, an ammonia-water mixture turbine and an ice storage system. In this paper, at first, each component of the bottoming stage of the ACGS is modeled based on experimental data. Especially for the ammonia absorption refrigerator, we introduced the new characteristic modeling, which was expressed by some spaced straight lines, to improve the precision of operational planning. Secondly, we discuss the effect of the delay of components on the operational planning. In concrete terms, the delays of the output of both the AAR and the AWMT were considered based on experimental data. Further, the operational planning to various demand patterns of real civilian sector is studied. The calculation results show that the optimum operational planning is derived and the bottoming stage of the ACGS is available for actual demand patterns.
