摘　　要：为降低MMC功率模块的研发和维护成本,文中基于RT-LAB对MMC的功率模块进行数字孪生设计。首先在RT-LAB上搭建MMC主系统的仿真模型,选取仿真电路中的某个功率模块作为数字虚体,以通过硬件搭建的MMC功率模块的实物电路作为物理实体,将数字虚体上的控制信号通过控制器OP5600发送到物理实体上。然后,将物理实体上的电气量通过控制器上的模拟量输入接口传送到上位机,实现对物理实体工作状态的实时监控。运行结果表明,文中所设计的功率模块与其在仿真电路中所对应的功率模块的电容电压与桥臂电流保持一致,达到了数字孪生的目的。该研究可为未来MMC功率模块的研发和维护提供参考,具有商业推广价值。In order to reduce the research and development and maintenance costs of MMC power module,the digital twin design of MMC power module based on RT-LAB is conducted. The simulation model of MMC main system is established on the RT-LAB,and a power module the simulation circuit is selected as the digital virtual body. The physical circuit of MMC power module constructed by means of hardware structures is used as the physical object,and the control signal on digital virtual body is sent to the physical entity by means of controller OP5600. The electrical quantity on the physical entity is transmitted to the upper computer through the analog input interface on the controller,so as to realize the real-time monitoring of the working state of the physical entity. The operation results show that the capacitance voltage of the power module designed in this paper and its corresponding power module in the simulation circuit are consistent with the bridge arm current,so as to achieve the purpose of digital twinning. This research can provide a reference for the research and development and maintenance of MMC power module in the future,and has commercial promotion value.
