摘　　要：柔性直流输电技术具有可控性强、对环境影响小、适合中小容量电力远距离输送等优点。总结和分析目前国内外关于柔性直流输电技术应用与设备的相关信息,结合南方电网规划和能源结构发展趋势,研究柔性直流输电技术在南方电网应用的必要性、可行性及应用前景,并提出南方电网应用柔性直流输电技术的如下可能项目:大规模海上风电场接入系统;实现区域联网以便提高电网供电可靠性;应用于珠三角等大城市负荷密集地区供电;向远方孤立负荷供电。VSC HVDC has advantages of high controllability,being friendly to environment and performing well in long dis-tance power transmission with small or medium capacity.Summarizing the key points of application and facility of VSC HVDC and taking the network planning and power-structure trend of China Southern Power Grid（CSG） into account,this paper re-searches the necessity,feasibility,and perspective of VSC HVDC for CSG.Certain promising applications are recommended,such as to connect large-scale offshore wind farms to the grid,to realize regional interconnections through VSC HVDC links so to improve power supply reliability,to supply power to the large cities in Pearl River Delta,and to the remote isolated load.
