摘　　要：为保证电网断电情况下列车正常运行,研究了一种同时具有高比功率和高比能量的复合电源系统,并提出了一种混合动力列车能量管理功率流分配策略。在Matlab/Simulink下,对列车运行中复合电源系统的各种功率需求进行了仿真。仿真结果表明,在功率流分配策略的控制下,蓄电池和超级电容器充分发挥各自优点,复合电源系统能够满足负载的各种功率需求;同时,复合电源系统能够充分吸收回馈能量,提高能量利用率;整个仿真过程中,蓄电池SOC维持在合理范围,避免了深度放电。In order to keep normal operation of the hybrid train without power grid, an energy power supply system with high specific power and high specific energy was studied. l-hen an energy management strategy for hybrid train was presented. For power demands of the train, the simulation of composite power system was given by Matlab/Simulink. Simulation results show that under this control of energy management strategy, battery and super-capacitor give full play to their advantages and composite power system can meet various power demands. Meanwhile, the composite power system is able to absorb the feedback energy by improving the energy utilization rate. During the whole simulation process, the battery SOC maintains in a reasonable scope and excess discharge is avoided.
