<p><P>PROBLEM TO BE SOLVED: To provide a cogeneration system keeping energy saving effect high without influenced by variation of exhaust heat recovery performance and power generation efficiency among products, and secular deterioration of exhaust heat collection quantity and power generation efficiency. <P>SOLUTION: In an operation control device 40 for the cogeneration system, a power generation stop energy saving effect calculation means (step 108) calculates energy saving effect when power generation of a power generation device 10 is stopped in a predetermined time zone, a power generation continuation energy saving effect calculation means (step 110) calculates energy saving effect when power generation of the power generation device 10 is continued in the predetermined time zone based on a learning value of fuel input characteristics and exhaust heat recovery characteristics which are characteristics of the power generation device 10, and a comparison means (step 112) comparing both energy saving effect calculated by both energy saving effect calculation means respectively and changing over whether power generation of the power generation device 10 is continued or stopped in the predetermined time zone based on the comparison result. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
