摘　　要：针对超高压输电线路串补装置不平衡电流调整存在盲目性的问题,提出基于邻域搜索的不平衡电流调整策略。根据串补装置的拓扑结构构建优化目标函数,制定串补装置邻域搜索策略,并制定电容器单元禁忌表用以确定搜索范围,采用MATLAB编写相应程序实现不平衡电流的优化调整。调整结果表明,该调整策略有效降低了串补装置不平衡电流,消除了不平衡电流调整的盲目性,大大提高了工作效率。Aiming at the blindness problem of unbalance current adjustment of series compensation device in EHV transmission line, the unbalance current adjustment strategy based on neighborhood search is proposed. The optimal objective function is constructed base on the topology of series compensation device, the neighborhood search strategy of series compensation device is developed, The searching range is determined by developing taboo table of capacitor unit. The optimal adjustment of unbalance current is realized by writing corresponding program by Matlab. The adjustment results show that the adjustment strategy reduces effectively the unbalanced current of series compensation device and eliminates the blindness of adjustment ,which increases the working efficiency.
