摘　　要：变电站电容器组反复出现投退,对电力系统的安全运行造成了影响。因此,对传统九区图控制策略进行分析,指出其中存在的问题,并在此基础上提出了十七图控制策略应用。通过应用改进后的控制策略,改善了无功补偿装置过程中出现的震荡等情况,保障了电力系统电压的稳定运行。Repeated switching--back of transformer substation capacitor banks has an impact on the safe operation of power system.This paper analyzes and points out the existing problems in the traditional nine-zone diagram control strategy, and puts forward the application of seventeen-chart control strategy on this basis.Through the application of improved control strategy,reactive power compensation is installed.The oscillation in the setting process has been improved,which can ensure the stable operation of the power system voltage.
