The invention discloses a ship gas-electric hybrid power system with a direct current network. The system comprises a natural gas storage tank, a natural gas engine, a gear box, a permanent magnet motor, a direct current bus, an energy storage converter and a lithium iron phosphate battery, the natural gas engine serves as a mechanical power system and is combined with an electric power system, and the problems that the engine power is insufficient and the endurance mileage is short are solved. On one hand, the permanent magnet motor with multiple modes is adopted, the number of the motors is reduced, and a power system is simplified, and on the other hand, the direct current networking system can better rectify the current of a power system, and the efficiency of the power system is improved. The method can be widely applied to the technical field of new energy.
