摘要

本文提出的模块化多电平变换器(MMC)子模块电容电压平衡方法[10]应用于高压直流输电，即MMC- vsc -HVDC。对MMC-VSC-HVDC的控制策略之一——直接控制策略进行了全面仿真，验证了平衡方法的有效性和通用性。为了证明平衡方法的鲁棒性，使有功功率和无功功率等参数在正负两侧的变化都在0.5pu左右。在MATLAB软件中进行仿真。

A voltage balancing method applied to direct control strategy of MMC-VSC-HVDC

The proposed balancing method [10] of sub-module capacitor voltage of modular multilevel converter (MMC) in this paper is applied to one of the applications, HVDC power transmission i.e. MMC-VSC-HVDC. One of the control strategies of MMC-VSC-HVDC i.e. direct control strategy has been comprehensively simulated to prove the effectiveness and versatility of balancing method. To prove the robustness of the balancing method, the variation of the parameters such as active and reactive power is made to around 0.5pu on positive as well as negative sides. The simulation is done in MATLAB software.
