摘　　要：云南与主网异步联网后,启动溪洛渡直流和鲁西背靠背直流参与初期黑启动可加快电网恢复速度。通过对传统直流参与黑启动时的交流系统短路容量、转动惯量要求以及直流系统控制模式选择的研究,确定了传统直流参与交流系统黑启动的技术条件。同时,以柔性直流作为试点研究对象,开展基于模块化多电平换流器(MMC)的新型直流参与交流系统黑启动的启动策略研究,提出分组分时序的负载投入方法。利用PSCAD电磁暂态模型进行仿真,结果验证了理论分析的正确性。When Yunnan power grid is in asynchronous operation with main Southern Power Grid, Xiluodu and Luxi HVDC can be started at the initial stage of black - start to speed up the recovery of power grid. The control modes of the traditional HVDC and the technical requirements of AC system for involving in the black - start are researched to set its technical conditions. At the same time, a new black - start strategy is researched when HVDC transmission system based on modular multilevel converter （MMC） is used in grid black - start. The simulation results with PSCAD electromagnetic transient model verify the correctness of the theoretical analysis.
