摘要
随着特高压交流电网建设进程的不断深入及锦苏、复奉、溪浙三大特高压直流的建成,四川电网将形成交直流混联外送的格局。针对特高压直流闭锁后功率转移情况,并结合特高压交流电网的建设进程,分析与特高压直流具有较强耦合关系的交流断面,为四川电网的安全稳定运行提供指导。
With the construction process of ultra - high voltage （UHV） AC power grid and the completion of Jinsu, Fufeng and Xizhe HVDC transmission lines, Sichuan power grid will form a pattern of AC/DC hybrid power delivery. Aiming at the situa- tion of power transfer after UHV DC blocking and combined with the construction process of UI-IV AC power grid, the AC sec- tions which have a strong coupling relationship with UHV DC is analyzed, which provides guidance for the safe and stable op- eration of Sichuan power grid.
