In a modular multilevel converter-based high-voltage direct current (MMC-HVDC) system, the dc fault ride through (FRT) control is an effective way to deal with a dc-side pole-to-ground (PTG) fault. However, the setting of FRT duration brings potential hazards: 1) MMC will face the ...
The full-bridge MMC-HVDC fault classification detection and protection method has the advantages when the FB (function block)-MMC-HVDC direct-current side has different types of faults, corresponding faults are detected out according to information of the monitoring points and classified and detected ...
The significance of this control scheme is that it permits the FB-MMC to operate with variable dc link voltage, including negative dc link voltage and zero, while full control over the power FB-MMC exchanges with ac grid is retained. Additionally, this paper provides comprehensive discussion of...

与MMC结构桥臂子单元不同, 由于这种变桥臂结构的工作原理特殊,其子单元电容能量波动无法在一个周期内自行维持平衡,需要加入额外的能量注入环节,因此必须研究与以往多电平变流拓扑不同的子单元电压恒定方法。此外, 由于每半个周期桥臂变换一次的工作特性,其电容两端电压波动规律也与目前较成熟的多电平模块化拓扑结构不...
