Modular Multilevel Converter Control Strategy Under Unbalanced Grid Condition
基于模块化多电平变换器(modular multilevel converter,MMC)各部分之间的功率关系,提出一种适用于电网电压不对称工况的MMC综合控制策略,包括直流母线电压控制、桥臂电容电压控制和交流侧电流控制.其中,桥臂电容电压采用层次化方法控制,在电网电压不对称时,通过调整直流母线功率在MMC三相桥臂间的分配,实现交流侧电流对称.内环采用桥臂电流直接反馈控制,可实现交流侧电流、直流母线电流和环流的三重控制,在电网电压不对称时无需交流…查看全部>>
Upon the power analysis of modular multilevel converter (MMC), this paper proposed a comprehensive control strategy for the DC-link voltage, the capacitor voltages and the AC-side currents of MMC under unbalanced grid condition. Multi-hierarchy method was adopted to control the capacitor voltage. Under unbalanced grid condition, the AC-side currents were controlled to be symmetrical by adjusting active power distribution among three legs of MMC. Inner curren…查看全部>>
