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.
