摘　　要：在农网线路无功补偿位置和补偿容量已经确定的情况下,提出一种智能控制策略,使整个网络损耗最小且实时电压不越限。建立以网损最小为目标的电容器优化投切模型,根据无功补偿对潮流影响的特点以及负荷特性,通过对Tabu搜索方法进行改进来寻求最优解。根据农村配电网现有的自动化条件,采用GPRS远程通信技术实现调度室上位机和线路中各智能无功补偿装置之间的数据交换,从而实现配电线路无功优化控制。An intelligent control algorithm are put forward on the condition that reactive power compensation location and capacity have been identified in rural distribution lines, which can keep real-time voltage qualified and network loss minimum. An optimal capacitor switching model is established aimed at a minimum network loss and to meet the requirement of computing speed according to reactive power compensation＇s influence on power flow and load characteristics. In light of the existent automation conditions in rural distribution network, technology of network and the GPRS is used to achieve data exchange between computers in scheduling room and each compensation devices in distribution lines and to achieve reactive power optimal control.
