车载超级电容储能系统间接电流控制策略

摘要

This paper discusses the control strategy of energy management in single railway vehicle with a on-board supercapacitor energy storage system.First,the structure of the energy storage system is introduced.Second,the model of energy storage system is built and a method to design the current loop for bi-directional DC-DC converter for energy storage is proposed.Finally,an indirect current control strategy is established to ensure an optimal power flow of single railway vehicle.The simulation and the experimental results verify that the new control strategy can avoid the voltage fluctuation and regeneration failure.%主要探讨了单列车车载超级电容能量管理系统的控制方法。首先对车载超级电容储能系统进行介绍;然后建立超级电容储能系统的数学模型,给出了超级电容储能系统充放电电流控制环的设计方法,提出了一种车载超级电容储能系统间接电流能量管理控制策略;最后通过仿真和实验结果证明该控制策略可以有效地抑制受电弓处电压波动,防止再生失效。
