Abstract:
PROBLEM TO BE SOLVED: To provide an energy supply system capable of setting a time with no supply of fuel gas to a power generation unit and a heat source unit to a set continuous time or more even when freezing prevention operation processing is executed in execution of stop processing for avoiding leakage determination.SOLUTION: An operation control unit C is constituted so as to execute stop processing for avoiding leakage determination which, before lapse of a leakage determination period, stops operation of a power generation unit Ha until a set releasing condition is satisfied, and to execute freezing prevention operation processing which, when a freezing prevention starting condition is satisfied, allows a freezing prevention combustor N to execute combustion operation until a freezing prevention finishing condition is satisfied, and when the freezing prevention starting condition is satisfied in execution of the stop processing for avoiding leakage determination, so as to execute the freezing prevention operation processing in a form for allowing the freezing prevention combustor N to execute combustion operation until a combustion amount increase finishing condition determined in a form for increasing a combustion amount of the freezing prevention combustor N more than the freezing prevention finishing condition is satisfied.SELECTED DRAWING: Figure 1
