摘要:
混合储能技术兼具能量型器件和功率型器件的优势，适用于地铁制动能量的回收利用。介绍了基于地面储能方式和双DC/DC架构的混合储能系统。研究了双向DC/DC变换器、锂电池组和超级电容组的参数设计方法，并采用MATLAB软件搭建仿真模型，与单一储能系统进行了控制效果、经济性的对比分析。结果表明：所设计的混合储能系统使牵引网电压在整个制动过程中均处于安全范围，系统投资成本和体积质量较小，性价比优势突出，同时实现了应急工况下备用电源的作用，验证了混合储能系统及其参数设计的合理性。
Abstracts:
Due to the advantages of both capacity and power devices, hybrid energy storage technology is suitable for the recovery and utilization of metro braking energy. In this paper, the hybrid energy storage system (HESS) based on ground mode and dual DC/DC architecture is introduced. With a study on the parameter design methods of the bidirectional DC/DC converter, battery and super-capacitor packs, a simulation model is built by MATLAB, and compared with the single energy storage system in terms of control effect and system economy. The results show that the designed HESS makes the traction grid voltage in safe range during the whole braking process. Because of the small investment cost and volume quality, the prominent cost-effective advantage, HESS can effectively realize the function of standby power supply under emergency conditions. Hence the rationality of HESS and its parameter design are verified.
