半桥MMC-HVDC单极接地故障的自适应限流控制

Integrating renewable energy sources into a bipolar modular multilevel converter (MMC) via a common ac bus can lead to an increase in ac in-feed current during a single pole-to-ground fault, resulting in bridge arm overcurrent and a blocking risk for the MMC. To address this problem, an adaptive current limiting control (ACLC) that accounts for the ac in-feed current boosting effect is proposed. F...
