摘　　要：超级电容储能系统应用于城市轨道交通可以实现良好的节能稳压的效果,本文首先分析了城轨交通列车再生制动电压限制特性以及等效24脉波不控整流机组的空载特性。在此基础上探讨了基于最大节能化的超级电容储能系统充放电阈值选择原则,并提出了基于动态阈值调节的储能系统控制策略,最后通过仿真和样机现场实验验证了控制策略的可行性。Ultracapacitor storage system can achieve good effect of energy saving and voltage stabilization in urban mass transit system, the paper analyze the characteristics of voltage limiting when the vehicle is regenerative braking firstly, then the characteristic of 24 pulse rectifier is analyzed too. On this basis the selected method of voltage threshold of charging and discharging is discussed which is based on optimal energy saving, then propose the control strategy of UCESS（Ultracapacitor Storage System） based on dynamic voltage threshold. In the end, the control strategy is verified through simulation and experiment.
