摘要
云南电网异步联网、远距离、大容量、超高压输电,运行特性复杂。2020年昆柳龙直流工程投产后,对送端云南电网的稳定问题带来新的考验。本文结合昆柳龙直流工程,分析了云南送端昆北站的稳定控制系统以及多端直流与传统两端直流稳控系统控制策略的差异性,分析了云南高周切机方案的适应性,以提升云南电网适应多端直流送电的安全稳定控制水平。
Large capacity ultra-high voltage transmission over a long distance,yunnan power grid asynchronous networking features complex quinn LiuLong dc project put into production in 2020,the sending of yunnan power grid stability proble ms of the new test in this paper,combined with quinn LiuLong HVDC project,analysis the stability of the yunnan sending kun north station control system,and on both ends of the multi-terminal dc and traditional dc control strategy of the differences between the stability control system,analyzes the cutter scheme of adaptability,yunnan high weeks to enhance the security and stability of yunnan power grid to adapt to the multi-terminal dc transmission control level.
