模块化多电平变流器(MMC)已成为电压型变流器高压直流系统的首选变流器拓扑。以前已经进行了出色的工作来为这些复杂的转换器开发急需的平均值模型(AVM)；然而，正如本文所强调的那样，存在一些限制。本文在现有模型的基础上，提出了大量的修正，得到了一种改进的MMC-AVM，该模型更加准确，可用于包括直流故障在内的更广泛的研究。
Modular multilevel converters (MMCs) have become the converter topology of choice for voltage-source converter-high-voltage direct-current systems. Excellent work has previously been conducted to develop much needed average value models (AVM) for these complex converters; however, there a number of limitations as highlighted in this paper. This paper builds on the existing models, proposing numerous modifications and resulting in an enhanced MMC-AVM, which is significantly more accurate and which can be used for a wider range of studies, including DC faults.
