摘　　要：充分利用电力系统分区思想,根据并联电容器组间的相关系数将城市高压网划分为小的独立优化单元,从而将一个大的电力系统分解为多个子系统。在各个子系统中利用传统的成熟算法进行计算,大大减少了在线计算时间。以在线负荷预测为依据,确定当前时刻往后24h内的并联电容器组和变压器分接头状态。所提算法在两个算例上进行了分析验证。The network partitioning approach is fully used in this paper for the reactive power optimization. According to the correlation coefficient between shunt capacitors, the urban high voltage power system is divided into small independence units. The traditional mature method is applied for each subsystem computation. Therefore, the required running time for online analysis is greatly reduced. Based on the on-line forecasted load powers, the shunt capacitors states and tap changers in the next 24 hours can be determined. The proposed approach is examined in two testing systems.
