储能系统在高冰级吊舱推进变频器的应用研究OA

In order to address the chanllenge of large power fluctuations and high dynamic performance requirements in the electric propulsion system of high-ice-class icebreakers under complex operating conditions,this paper has investigated the application of an energy storage system consisting of lithium batteries and supercapacitors within pod propulsion frequency converter.Based on actual ice zone conditions,the operational requirements and modes of the energy storage system are analyzed.A power distribution method based on the Grey Wolf Optimizer(GWO)-optimized Variational Mode Decomposition(VMD)is proposed.Simulation results show that the proposed method effectively achieves power distribution within the energy storage system,reduces charging and discharging stress on lithium batteries,and provides a reference for the capacity configuration and engineering applications of the energy storage system.
