摘要
以云南电网为实例,研究分析了交直混联电网中直流输电对电网暂态稳定性的影响,着重讨论了如何利用直流有功功率调制手段提高电网的安全稳定运行性能,并给出了这种措施在电网中的实现方案。
Based on the Yunnan power grid, this paper introduces the characteristics of DC transmission in AC and DC hybrid power system and the effects on transient stability, which is the most important, we studied how to use the method of DC active power modulation to improve the security and stability performance of the power grid. At last, this paper gives some measures to the realization the plan in the grid.
