摘要
为了解决双流制牵引供电系统存在的直流侧网压波动,再生制动能量不能高效利用等问题,提出了一种基于混合储能的双流制牵引供电系统能量传输装置。首先,该方案研究设计了双流制牵引供电系统能量传输装置的拓扑结构。然后,为了实现快速准确的控制,制定了一种包括能量管理层和变换器控制层的分层控制策略,根据系统内部能量流动关系,划分了3种工作模式与6种工况。最后,通过MATLAB/Simulink仿真平台搭建了仿真模型,在各种工况下进行仿真模拟,结果均实现了补偿目标。
In order to solve the problems of dual-stream traction power supply system such as DC-side network voltage fluctuation and inefficient utilization of regenerative braking energy,this paper proposes a hybrid energy storage based energy transfer device for dual-stream traction power supply system.First the scheme studies and designs topology of the energy transfer device.Then in order to achieve fast and accurate control,a hierarchical control strategy including energy management layer and converter control layer is developed.According to internal energy flow relationship of the system,three operating modes and six operating conditions are classified.Finally a simulation model is built by MATLAB/Simulink simulation platform,and simulations are performed under various operating conditions,and the results all achieve the compensation objectives.
