Gas engine power generation system

Abstract

The present disclosure relates to a gas engine power generation system, having an engine configured to generate mechanical energy by burning an air-fuel mixture supplied from a mixer, which mixes air filtered by passing through an air cleaner, and fuel of a predetermined pressure which has passed through a zero governor, in which the gas engine power generation system converts the mechanical energy of the engine into electrical energy. The gas engine power generation system according to an embodiment of the present disclosure includes: an intake path having a first intake passage and a second intake passage in which air to be supplied to the mixer flows; an intake passage controller configured to open either one of the first intake passage or the second intake passage and to close the other one; a coolant pump configured to supply coolant to the engine; a radiator configured to dissipate heat of the coolant having passed through the engine; an intake air heater provided in the intake path at a portion where the second intake passage is formed, and configured to dissipate heat of the coolant having passed through the engine; a coolant passage controller configured to distribute the coolant, having passed through the engine, to the coolant pump, the radiator, and the intake air heater; and a controller configured to control operations of the intake passage controller, the coolant passage controller, and the coolant pump based on temperature of the coolant, having passed through the engine, and load information of the engine.
