简要描述了MMC结构和工作原理。MMC-HVDC在风电场黑启动和风电场并网方面有具有很大的优势，因此，南澳岛风电场改造为了经MMC-HVDC接入电网的方式。提出了风电场柔性直流输电送端换流器直流侧充电方法、风电场黑启动并网方法以及受端和送端控制策略。该方法和控制策略已在南澳多端柔性直流输电示范工程中的成功应用。南澳柔性直流输电示范工程的成功投运验证了MMC-HVDC的优越性和所使用控制方法的正确性。

This paper briefly describes the structure and working principle of MMC. As MMC-HVDC has a great advantage in the wind farm black start and wind farm’s integration with grid,Nan’ao Island Wind Farm is innovated and transformed into MMC-HVDC patten. This paper proposes the DC side charging method,and the black start-up and grid connection method and receiving end and sending end control strategy of MMC-HVDC. The method and control strategy have been successfully implemented in Nan’ao VSC-HVDC demonstration project,and its successful operation has proved the superiority of MMC-HVDC and validity of the control strategy.
