摘　　要：为在远景年充分利用天广直流输电走廊,从南方电网中长期电力流和技术路线出发,分析了送、受端电网送出和消纳规模,研究了天广直流两端换流站改造能力。针对扩容天广直流、马窝站退役、新增直流线路等多种因素,拟订了4种可能的改造方案,通过技术、经济多方面比较后,提出天广直流改造扩容规模、初步可行方案及改造时机。To fully utilize the transmission line corridor of Tianshengqiao-Guangzhou HVDC Project in the distant future, according to the long-term flow and technical route of China Southern Power Grid （ CSG）, the capacities of the sending power grid and the receiv- ing power grid are analyzed, and the capacities of Tianshengqiao-Guangzhou HVDC converter stations on both sides are studied, then four transformation plans are proposed considering the expansion of Tianshengqiao-Guangzhou HVDC converter stations, retirement of the Mawo converter station, and construction of new HVDC lines. By comparison on transformation technology and costs, the trans- formation and exoansion scale, oreliminarv feasible plan and opportunity time are put forward.
