<p><P>PROBLEM TO BE SOLVED: To provide a cogeneration system, suitably setting the operating conditions of a cogeneration device according to the passage of the operation time of the cogeneration device or the ambient temperature. <P>SOLUTION: In this cogeneration system, the operation control means 5 obtains time series estimated power load data and time series estimated thermal load data according to the time series past power load data and the time series past thermal load data. The operating conditions of the cogeneration device 1 are set according to the obtained estimated power load data and estimated thermal load data and the power generation efficiency and exhaust heat efficiency, and the cogeneration device 1 is operated under the preset operating conditions. Further the system includes an efficiency obtaining means 50 for obtaining the efficiency to output relationship between the power generation output in the power generation output control range of the cogeneration device 1, which varies with the passage of the time or a change in ambient temperature and the power generation efficiency or exhaust heat efficiency with the passage of time or the change in the ambient temperature, and the operation control means 5 obtains the power generation efficiency or the exhaust heat efficiency from the efficiency to output relationship obtained by the efficiency obtaining means 50. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
