摘　　要：级联H桥拓扑具有高效、可靠、模块化等优点,广泛应用于高压电机驱动及大功率无功功率补偿等领域。将储能电池组并入到级联H桥直流侧,形成级联H桥储能系统,则可以实现直接对巨量电池进行分割管控,同时借助于级联H桥的拓扑结构,大量的电池只进行串联无并联,从根本上解决了环流问题。由于级联H桥技术以及电池的加入导致级联H桥系统较为复杂,门槛高、开发成本和周期长,本文借助MATLAB、RTLAB仿真机和DSP控制系统,提出了一种高压级联储能的半实物仿真平台,可以实现算法的快速验证,减少整机开发时间;另外一方面为后续进行整个半实物测试提供了可能。The cascaded H-bridge topology has advantages such as high efficiency,reliability,and modularity,and is widely used in fields such as high-voltage motor drive and high-power reactive power compensation.By integrating the energy storage battery pack into the cascaded H-bridge DC side to form a cascaded H-bridge energy storage system,it is possible to directly segment and control a large number of batteries.At the same time,with the topology of the cascaded H-bridge,a large number of batteries are only connected in series without parallel,fundamentally solving the circulation problem.Due to the cascaded H-bridge technology and the addition of batteries,the cascaded H-bridge system is relatively complex,with high thresholds,development costs,and long cycles.In this paper,using MATLAB,RTLAB simulation machines,and DSP control systems,a semi physical simulation platform for high-voltage level energy storage is proposed,which can achieve fast algorithm verification and reduce overall development time;On the other hand,it provides the possibility for subsequent semi physical testing.
