摘要:
超级电容快速的充放电特性能够满足地铁车辆频繁启停的工作需求。利用恒压双向功率流原理，建立了地铁车辆车载超级电容储能系统模型。在满足地铁车辆制动能量回收的基础上，对超级电容器组进行优化配置。建立了车载超级电容储能系统的全寿命周期成本计算模型、超级电容寿命计算模型及经济效益计算模型。通过实际算例对车载超级电容储能系统中的超级电容进行了配置，同时对其经济性进行了评估。结果表明，系统能达到预期的经济效益。
Abstracts:
The rapid charging and discharging characteristics of supercapacitor can meet the need of metro vehicle frequent starting and stopping. Based on the principle of constant voltage bi-directional power flow, a model of metro vehicle on-board supercapacitor energy storage system is established. On the basis of satisfying the recovery of metro vehicle braking energy, the configuration of supercapacitor banks is optimized. The full life cycle cost calculation model, supercapacitor life calculation model and economic benefit calculation model of the on-board supercapacitor energy storage system are established. Through practical calculation case, the supercapacitor in the on-board system is configured, its economy is evaluated. The result shows that the system can achieve the expected economic benefit.
