摘　　要：新型“SEN Transfomer”(IST)是一种由三相双绕组变压器和有载调压开关组成的电磁式统一潮流控制器,较ST具有更灵活的潮流调控能力与更大的潮流调控范围。文中详细介绍了IST的拓扑结构及基本工作原理,推导了IST的功率注入模型。引入线路有功潮流性能指数,根据IST基本选址原则及计算得到的潮流灵敏度系数,以提高系统有功潮流调节能力为目的,对IST的安装位置进行了选择。在IEEE 14节点系统中对所提出的方法进行了验证,结果表明在该方法计算得到的支路上安装IST后,系统的有功潮流分布得到了明显的改善。The novel SEN Transformer(IST)is an electromagnetic unified power flow controller composed of three-phase double-winding transformer and on-load voltage regulator switch,which has more flexible power flow control ability and larger power flow control range than ST.Firstly,the topological structure and basic working principle of IST are introduced in detail,and the power injection model of IST is deduced.According to the basic site selection principle of IST and the calculated sensitivity coefficient of power flow,the installation position of IST is selected to improve the regulation ability of active power flow.Finally,the proposed method is validated in the IEEE 14-bus system.The results show that the distribution of active power flow of the system is obviously improved after IST is installed on the branch road calculated by the proposed method.
