The invention relates to a locomotive electric transmission system, in particular to a high-reliability locomotive electric transmission system and a control method thereof. The problem that a traction system of an existing locomotive electric transmission system is poor in power supply redundancy capacity is solved, and the problem that the direct-current side of a train power supply system contains secondary pulsation is solved. The high-reliability locomotive electric transmission system comprises a transformer, a traction system, a train power supply system, a diesel generator power supplysystem and a storage battery. Through the modes of multi-layer redundancy main circuit topology design, multi-layer redundancy control switching and the like, the reliability and the flexibility of atraction system and a train power supply system are greatly improved, and meanwhile, the riding comfort and the riding convenience of passengers are improved; the system has the capacity of providinglong-time and short-time power supply for a traction system, the urgent probability of a locomotive is greatly reduced, and the flexibility and safety of the locomotive are improved.

    本发明涉及机车电传动系统,具体为一种高可靠性机车电传动系统及其控制方法。解决现有机车电传动系统的牵引系统的供电冗余能力较差的问题,以及列车供电系统的直流电侧含有二次脉动的问题。高可靠性机车电传动系统,包括变压器、牵引系统、列车供电系统、柴油发电机供电系统和蓄电池。本发明通过多层冗余主电路拓扑设计和多层冗余的控制切换等方式,大大提高了牵引系统、列车供电系统的可靠性和灵活性的同时,提升了旅客乘坐的舒适性和便捷性;本发明同时具备为牵引系统提供长时和短时供电能力,大幅降低了机车急迫的概率,提高了机车灵活性和安全性。
