轨道交通混合储能系统的研究与实现

为给轨道交通储能系统的前期研究及后期验证提供实验条件，结合轨道交通实际运行工况、功率参数和容量配置等，围绕储能元件特性、变流器系统设计展开研究，选取超级电容和锂离子电池作为储能元件，以双DC/DC拓扑为主电路，dSPACE为控制器，搭建具有牵引耗能和制动馈能的轨道交通混合储能系统。

Research and Implementation on Hybrid Energy Storage System of Rail Transit

In order to provide experimental conditions for preliminary studies and post-verification of the energy storage systems, the research was carried out, based on the actual operating conditions, power parameters, capacity configuration, focusing on the characteristics of the energy storage elements and the design of converter system. The research chose ultracapacitor and lithium-ion battery as the energy storage element, the dual DC/DC converter topology as the prototype model, and dSPACE as the control processor to build a hybrid energy storage system to simulate the traction energy consumption and regenerative braking energy.
