摘要

子模块故障是模块化多电平换流器 (modular multilevel converter

MMC) 中存在的典型问题，现有穿越策略研究中未能兼顾考虑 MMC 的暂态过程共模电压 (common mode voltage

CMV)。针对这一问题，提出了一种无冗余 MMC 子模块故障下暂态 CMV 调制级抑制策略。首先基于首尾衔接调制控制任意时刻投入运行的上、下桥臂子模块的数量相同，实现稳态运行下的 CMV 抑制。然后在首尾衔接调制下进行子模块故障穿越和补偿策略设计以实现暂态 CMV 抑制，且无需抬高故障桥臂电容电压。从稳、暂态 CMV 机理出发，对所提调制与补偿方案的原理、实现过程、实现效果与改进方案进行了探讨。仿真与实验验证了所提方案的正确性与有效性。

Abstract

Submodule faults are typical problems in modular multilevel converter (MMC) systems. Existing ride-through strategies often fail to adequately consider the transient common mode voltage (CMV) during dynamic processes. To address this issue

a transient CMV modulation and suppression strategy for MMC submodule faults without redundancy is proposed. First

based on the head-tail connection modulation control

the number of inserted submodules in the upper and lower arms at any instant remains equal

thereby achieving CMV suppression under steady-state operation. Then

under this modulation framework

a submodule fault ride-through and compensation strategy is designed to achieve transient CMV suppression without raising the fault arm capacitor voltage. From the perspective of steady-state and transient CMV mechanisms

the principles

implementation process

performance characteristics

and possible improvements of the proposed modulation and compensation scheme are discussed. Finally

simulation and experimental results verify the correctness and effectiveness of the proposed scheme.
