The traditional way of consuming the regenerative braking energy (RBE) of the suspended train through the braking resistor leads to increasingly prominent problems such as the low utilization rate of the RBE. If we can realize the efficient utilization of RBE in maglev transportation, it will be beneficial to realize energy saving and consumption reduction of maglev traffic and the realization of the 3060 dual carbon goal. This paper analyzes the topology structure and operation principle of the doubly-fed linear motor (DFLM), as well as its energy flow characteristics under different operating states. The topology structure and the corresponding energy management strategy of the RBE utilization system on the stator side, and the feedback energy utilization system on the mover side of the suspended train based on the DFLM are given. The system's feasibility to achieve dynamic power distribution is verified by analyzing the train operating state and the transition conditions between the four operating modes of the stator-side RBE utilization system and the specific operating conditions in the operating mode. A technical method is provided for realizing efficient utilization of the RBE in maglev traffic.
