摘要： 基于模块化多电平换流器（MMC）的柔性直流输电方式，由于其开关器件的数量是传统两电平或三电平换流器的几百倍，故传统的仿真软件需要花费更长的时间才能得到结果。系统仿真时间的显著增加使得系统仿真的时效性和实用性大大降低。为此引入实时仿真平台RT-Lab，减少系统仿真在柔性直流输电系统开发周期中所占比例。并通过同一种控制算法在RT-Lab和Matlab下的仿真进行了验证，结果表明RT-Lab能够显著地减少系统仿真时间，并保证运行结果的有效性和精确性。

Abstract: Flexible DC transmission system based on modular multi-level convertor due to its inherent advantages reciving more and more attention . But the number of switching devices is hundreds of times of the traditional two-level or three-level convertor , so the tradional simulation software will take more time to get result. Because of the time of system simulation significantly increased, so the timeliness and practicality of system simulation is greatly reduced. Using the real-time simulation platform RT-LAB to reduce the proportion of system simulation in flexible DC transmission system development cycle. And verified through the same control algorithm simulation in RT-LAB and Matlab, the results show that RT-LAB can significantly reduce the simulation time, and ensure effectiveness and accuracy of the result.
