摘　　要：针对南方电网串补工程引发的次同步谐振的可能性进行了分析研究。研究表明除百色串补工程外,平果和河池串补工程可以不考虑其对次同步谐振的影响,且百色串补中的马百线对待研机组的影响可以不予考虑。并用频率扫描法分别分析了百色串补线路在不同串补度下的谐振问题,说明了长距离输电系统在高串补度下容易引起次同步谐振。The SSR （subsynchronous resonance） possibility caused by series - capacitor compensation project in China Southern Power Grid is analyzed. The result shows that the series - capacitor compensation projects in Pingguo and Hechi do not cause the SSR except the series - capacitor compensation project in Balse, and it has no effect on the series - capacitor compensation of Mabai. The frequency scanning method is used to analyze the series - capacitor compensation of Baise in different compensation degrees, and the result shows that the long - distance transmission system with high series - capacitor compensation will cause SSR easily.
