<P>PROBLEM TO BE SOLVED: To provide a cogeneration system capable of appropriately setting the operation conditions of a cogeneration device according to the passed operation time of the cogeneration device or the temperature. <P>SOLUTION: An operation control means 5 sets the operation conditions of the cogeneration device based on estimated power load data and estimated heat load data which have been obtained, and power generation efficiency and waste heat efficiency of the cogeneration device 1, and operates the cogeneration device 1 under the set operation conditions. An efficient means 50 is provided for obtaining efficient output relation which changes as time passes between power generation output and the power generation efficiency or the waste heat efficiency of the cogeneration device 1 along with passing of the time. In a normal operation mode in which the cogeneration device 1 is operated under the set operation conditions, the efficiency obtaining means 50 obtains the respective power generation outputs at a plurality of times and the corresponding power generation efficiency or the waste heat efficiency based on actual operation data at a plurality of the times, and obtains the efficient output relation based on the obtained data. <P>COPYRIGHT: (C)2009,JPO&INPIT |
