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.

    本发明公开了一种带直流组网的船舶气电混合动力系统。该系统包括天然气存储罐、天然气发动机、齿轮箱、永磁电机、直流母线、储能变流器、磷酸铁锂电池,通过天然气发动机作为机械动力系统,与电力动力系统进行结合,解决了发动机功率不足,续航里程短的问题。一方面采用了包含多种模式的永磁电机,节省了电机数量,简化了动力系统,另一方面直流组网系统能够更好地对电力系统的电流进行整流,提高了电力系统的效率。本发明可广泛应用于新能源技术领域内。
