摘　　要：针对轨道交通再生制动能量问题,本文开展基于磁悬浮飞轮阵列储能型制动能回收节能系统研究。通过分析牵引供电系统结构,分别对列车进站的制动方式和能耗特性进行了分析,并给出了增加储能装置前后的耗能对比情况。在此基础上,设计一种基于飞轮储能阵列的直流电能循环利用系统,可实现车辆进站制动能量的快速吸收和出站时的功率补偿,通过对飞轮阵列关键指标进行论证,确定了飞轮并联方案和容量配置。最后,搭建了飞轮阵列储能实验系统,通过飞轮对拖充放电控制和性能测试验证了系统的有效性,为城市轨道交通再生制动能量的回收和节能奠定基础。For the problem of the regenerative braking energy in the rail transit, some research on a kind of magnetically suspended flywheel array-based energy recovery system is done. Through analysis on the structure of the traction power supply system, the braking methods and energy consumption during the rail pulling in are introduced. And then the contrast results of the energy consumption are provided before and after adding the energy-storaged equipment. Based on this, a kind of the flywheel energy-storaged array-based DC power recycling system is designed which can be used to achieve a fast braking power absorption during pulling in and power compensation during pulling out of the rail train. With the argumentation of the flywheel key performance indices, the parallel strategy and the capacity assignment are demonstrated. Finally, the experimental platform of the flywheel energystoraged array is developed with the real test system. The mutual-driven charging and discharging results can be able to demonstrate the effectiveness of the designed.
