| Summary: | Strengthening the research and application of regenerative braking energy utilization technology is an important measure to promote the low carbon development of AC electrified railways. In order to further improve the utilization rate of regenerative braking energy, effectively solve the problem of insufficient absorption capacity of power load, taking cost control into account, a kind of synergistic utilization technology combining transfer and storage was proposed. Firstly, the composition and working principle of the synergistic utilization device were explained, and the hierarchical control architecture based on master-slave control was studied. Secondly, following the principles of transfer priority and maximum utilization, the control strategy that takes into account the multiple constraints of regenerative braking power, electric load demand power and rated power of the device was formulated. Then, based on the field measured data, the correctness and effectiveness of the control strategy were simulated and verified, and the energy-saving effect was analyzed. Finally, considering factors such as cycle life, safety and reliability, lithium titanate batteries was selected as the energy storage medium, and the investment cost and the full life cycle benefits were calculated on this basis. The research results show that the synergistic utilization technology can realize the efficient utilization of regenerative braking energy, so it has a good effect of cost and energy saving and high engineering application value. |
