HYBRID POWER GENERATION SYSTEM AND OPERATING METHOD OF HYBRID POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a hybrid power generation system in which the durability of a solid oxide fuel cell itself is improved with respect to frequent repetition of start and stop, and time required from temporary stopping of an SOFC to re-starting can be shortened.SOLUTION: A hybrid power generation system 1 generates power by combining an SOFC 10 and an MGT 50, and includes an operation mode in which the SOFC 10 is shifted to a stand-by state when the SOFC10 is temporarily stopped in a state where the MGT 50 is operated. This system is provided with a heating part for raising temperature in a power generation room in order to be shifted to the stand-by state and maintain the temperature in the stand-by state.
