Single‐clamp sub‐module (SCSM) combining the cost and technological advantages has become one of the next modular multilevel converter (MMC) sub‐module topologies in response to DC fault aspect. It describes the topological structure and working conditions based on SCMMC (Single‐Clamp MMC) and proposes the three‐stage start‐up processes of SCMMC. The paper has made a detailed study on the black‐start scheme of the blackout terminal converter when SCMMC‐HVDC is used in grid black start. The active‐side SCMMC orderly rotation trigger control strategy and the passive‐side SCMMC orderly rotation bypass control strategy are proposed targeted. The paper proposes the corresponding start‐up procedures for the SCMMC‐HVDC system. At last, simulation models are established in PSCAD/EMTDC, the simulation results have validated the efficiency of the proposed black‐start scheme for the converter of the blackout terminal.
