【摘要】：模块化多电平换流器(modular multilevel converter,MMC)已经展现出极其重要的工程应用前景,MMC的高效建模方法是开展一系列理论性和工程性问题研究的基础。文中分别针对不同时间尺度和不同的应用场景,对国内外已有的涉及到MMC建模的主要文献进行条分缕析式地整理归纳,进而探索该领域的研究前沿和关注的核心问题。对所提出的3种微秒级电磁暂态精确模型,也即基于受控源的MMC通用提速模型和基于后退欧拉法和梯形法的MMC戴维南等效整体模型进行了严格的横向对比和仿真验证;同时,针对所提出的电磁暂态平均简化模型,验证了其在仿真严重交直流暂态过程中的适用性,分析其适用场景和使用方法。最后,文中介绍了MMC机电暂态模型和实时仿真模型的主体思想,并指出二者具有很好的研究和应用前景。
[Abstract]:Modular multilevel multilevel converters have shown very important prospects for engineering applications. The efficient modeling method is the basis of a series of theoretical and engineering problems. Different application scenarios, The main literatures related to MMC modeling have been sorted out and summarized in this paper, and the research frontier and the core problems concerned in this field have been explored. Three kinds of microsecond electromagnetic transient accurate models are proposed. In other words, the MMC general speedup model based on controlled source and the equivalent integral model of MMC based on backward Euler method and trapezoid method are strictly compared and verified by simulation. The applicability of the model in the simulation of severe AC / DC transient process is verified, and the applicable scenarios and application methods are analyzed. Finally, the main ideas of MMC electromechanical transient model and real time simulation model are introduced. It is pointed out that both of them have a good prospect of research and application.
