The invention provides an urban rail intelligent traction power supply system and a control method thereof, the system adopts a set of bidirectional converter unit to replace an original set of diode rectifier unit, and a set of energy operation control system is arranged on a top layer to form a novel intelligent traction power supply system. Two traction operation modes are set by comprehensively considering the system safety, the energy-saving effect, the equipment utilization rate and the like, one mode is that a bidirectional converter unit supplies power for main traction, and a rectifier unit is in hot standby; 2, the power of the bidirectional converter unit and the rectifier unit is output in a balanced manner; the energy operation control system effectively distributes power between the bidirectional converter unit and the rectifier unit according to train loads, active traction power supply is achieved, the voltage of a direct-current traction network is improved and stabilized, line loss and rail potential are reduced, and the power supply distance is increased.

    本发明提供一种城轨智能牵引供电系统及其控制方法,系统采用1套双向变流机组替代原有1套二极管整流机组,并在顶层设备1套能量运控系统,构成新型智能牵引供电系统,在控制策略上,综合考虑系统安全性、节能效果、设备利用率等设置两种牵引运行模式,一是双向变流机组为主牵引供电,整流机组热备;二是双向变流机组、整流机组功率均衡输出;能量运控系统根据列车负荷有效分配双向变流机组与整流机组之间功率,实现主动式牵引供电,提升并稳定直流牵引网电压,降低线路损耗、轨电位,增加供电距离。
