摘　　要：云广±800kV直流双极投产后,南方电网交直流并联运行、强直弱交的特性更加明显,会给电网安全稳定运行带来新问题。鉴此,研究了云广直流投产后的安全稳定特性、西电东送能力、严重故障的影响及动态稳定性等,分析了联网及孤网两种正常运行方式,提出了云广直流运行方式的安排原则以及调试和运行的建议。As Yunnan-Guangdong ±800 kV DC system （the YG system） being in bipolar operation,the characteristics of AC/DC hybrid network with a strong DC system and a weak AC system in China Southern Power Grid （CSG） become more obvious,and thus new issues of security and stability of CSG will appear.This paper discusses several aspects of CSG with the YG system in bipolar operation,including the security and stability features,capacities of transmission power from the West to the East,effects of serious faults,dynamic stabilities.The connected and isolated operation modes of the YG system are analyzed,and the principles for the modes arrangement as well as the suggestions for the YG system testing and operating are given.
