摘　　要：以南方电网2008年夏季大运行方式为基础,对西电东送通道进行电压灵敏度分析,找出电压薄弱点和对电压较为敏感的关键母线。同时通过动态仿真扫描西电东送输电故障,得出会导致系统电压失稳的输电通道的严重故障,并针对故障提出相应解决措施。Based on peak operation mode of South China Grid in 2008 summer, this paper conducts the voltage sensitivity analysis on power transmission channel from west to east, to find out weak points of voltage and key bus which is sensitive to voltage fluctuation. Meanwhile, serious faults on power transmission channel which would lead to voltage fluctuation are found through scanning power transmission channel from west to east with dynamic simulation technology. The corresponding solutions of each fault are submitted.
