摘　　要：介绍了柔性直流配电网动态模拟系统设计与实现,该动态模拟系统为多端可变换柔性直流配电网试验系统,使用了工程中应用的控制保护装置,能够实现多种电网主回路拓扑以及多种子模块拓扑的动态模拟,给出了动态模拟系统中设备的参数设计计算,介绍了故障模拟以及故障点设置,可应用于柔性直流配电网系统暂态和稳态特性的研究,并且能够为柔性直流配电网关键设备的开发研制提供试验检测基础。Design and implementation of a dynamic simulation system of flexible DC system are introduced. The developed convertible dynamic simulation system can simulate a multi-terminal flexible DC system,with the control and protection devices used in engineering. The main wiring forms and the SM can be transformed in a variety of topologies. The parameters design and calculation of main equipment are given,as well as the fault simulation and fault point setting.The dynamic simulation system can be applied to study the transient and steady-state characteristics of flexible DC power system,providing test basis for design and development of the key equipment of flexible DC power network.
