Abstract
(EN)
A gas engine power generating system is disclosed. The gas engine power generating system may comprise: an engine; a pump that supplies coolant to the engine; a radiator that radiates heat of the coolant discharged from the engine; a flow regulator that distributes, to the pump and the radiator, the coolant discharged from the engine; a sensor that detects the inflow and outflow temperature of the coolant of the engine; and a control unit that calculates the temperature of an inner wall of the engine on the basis of the temperature information of the coolant obtained from the sensor and adjusts the flow regulator and the pump.
