摘　　要：在传统九区图策略的基础上,提出了根据变电站实时运行数据.通过潮流方程计算出控制变量的调节范围,并采取电容器优先动作的一种变电站电压无功控制(VQC)策略.仿真结果表明:与传统九区图相比,VQC策略满足电压无功调控的要求,能有效减少变压器分接头的调节次数.Based on the traditional nine-zone theory,the regulating range of control variables was calculated through the power flow equation in accordance with the real time operating data,and one VQC strategy of transformer substation was proposed based on priority operation of capacitor.The simulation results indicate that compared with the traditional nine-zone technology the introduced VQC strategy can meet requirements of voltage reactive power control and efficiently reduce adjustment times of the transformer tap.
