结合云南直流输电工程均是以大型水电站为依托的实际，研究了直流并网、孤岛运行方式对云南电网的供需形势、潮流分布及安全稳定水平的影响，并进一步模拟分析了直流紧急功率支援等新技术在云南电网运用的效果。研究发现直流孤岛加剧了云南“丰余枯缺”的用电矛盾，但可基本消除多回直流故障导致主网失稳的风险，提高系统稳定性。

This paper studies the influence of the the two operation modes to Yunnan power grid supply and demand situation , trends and distribution of safe and stable level. And then studies the effect of new technologies on the Yunnan Power Grid such as the DC emergency power support. HVDC operating as island exacerbated conflicts that Surplus in the flood season and shortages in the dry season, but it can eliminate the risk of instability in the main network because of DC fault, improve system stability.
