模块化多电平换流器无环流仿真模型

为简化仿真控制策略和提高仿真效率，对桥臂环流抑制功能投入的模块化多电平换流器（MMC）进行整体建模，提出一种无环流仿真模型。首先分析了MMC单个子模块工作的电气特性，然后以此为基础推导出换流器相单元电容电压之和与交、直流侧电气量的关系，最后对三相相单元进行整体建模得到反映换流器外特性的仿真模型。在MATLAB中利用模型搭建柔性直流输电系统并对各种运行工况进行仿真，其仿真结果与基于RTDS详细模型仿真结果一致，充分说明了本文模型的可行性与准确性。该模型适用于仅关注换流器外特性的场合，具有仿真速度快、仿真精度高、适用性广的特点。

A Simulation Model Without Circulating Current of
Modular Multilevel Converter

In order to simplify the simulation control strategies and improve the simulation efficiency, this paper proposes a simulation model without circulating current by integral modeling of modular multilevel converter (MMC) running under the bridge arm circulating current suppression function. Firstly the electrical characteristics of the single sub-module of the MMC were analyzed, on the basis of which the relationship between the total capacitor voltage of the phase unit and the electric parameters of the AC and DC side was then derived, finally the three-phase unit was integral modeled to achieve the external characteristic of the converter. We used this model to build a flexible HVDC system in MATLAB and carry out the simulation in various operating conditions, whose simulation results agreed with the detailed model simulation results based on RTDS. It fully demonstrates the feasibility and accuracy of the proposed model. This model is suitable for the situation where only the external characteristics of the converter are concerned, and it has the characteristics of high speed, high accuracy and wide applicability.
