Title:
COGENERATION SYSTEM, AND OPERATION CONTROL METHOD THEREOF
Document Type and Number:
Japanese Patent JP2015063989
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technology capable of suppressing unexpected shortening of a service life while effectively utilizing generated power of a cogeneration device and exhaust heat, in a cogeneration system in which the cogeneration device is operated according to a thermal load, and an operation of the cogeneration device is controlled in a state that an output in operating the cogeneration device follows a power load within an output set range.SOLUTION: An operation frequency adjustment processing is carried out to adjust an operation frequency of a cogeneration device by changing at least one limited output of an upper limit output Pmax and a lower limit output Pmin of an output set range. In the operation frequency adjustment processing, the limited output of the output set range is raised when the operation frequency of the cogeneration device is adjusted to the decrease side, and the limited output of the output set range is lowered when the operation frequency of the cogeneration device is adjusted to the increase side.
