Train Braking Energy Storage System Based on Super Capacitor and Its Control Technology

针对分散式供电系统部分回馈能量不能完全被地铁业主重复利用的问题,文章通过对城轨牵引供电系统的特性分析,提出了一种再生制动能量存储系统方案,其利用超级电容器储能,采用Buck和Boost双模式闭环控制,很好地适应了城轨列车频繁起/制动、短时制动功率大、持续时间较短、制动电能小的特性。研究性试验及带车运行试验结果验证了该系统的功能及性能特性。

For the problem that partial feedback energy of decentralized power supply system not be completely reused by subway owners, it analyzed the characteristics of urban rail traction power supply system and proposed a scheme of regenerative braking energy storage system. It uses super-capacitors for energy storage and adopts Buck and Boost dual-mode closed-loop control, well adapting to the characteristics of urban rail train such as frequent start / braking, short-term braking power, short duration and small braking power. The results of research tests and vehicle running tests verified the functional and performance characteristics of the system.
