中文摘要：

为了增强输电潮流可控性,提出了一种“Sen”变压器（ST）和统一潮流控制器（UPFC）公用激磁绕组的电磁混合式潮流控制器（EHPFC）。详细推导了ST和UPFC的最优容量配合关系,优化了EHPFC的控制策略。分析了EHPFC和UPFC对潮流调控的稳态特性和暂态特性。进一步采用PSD-BPA软件,研究了EHPFC对IEEE14节点复杂环网潮流的调控性能。搭建了双端系统传输潮流的硬件实验模型,对EHPFC调控潮流进行了模拟实验。仿真和实验结果表明,EHPFC可以在较低的成本下,实现和UPFC相同的潮流调控能力,同时弥补了ST无法进行连续潮流调节的不足,验证了EHPFC控制潮流的性能。

英文摘要：

In order to enhance the controllability of power flow in transmission network, an electromagnetic hybrid power flow controller（EHPFC） is proposed, in which ＂Sen＂ transformer（ST） and unified power flow controller（UPFC） share the excitation winding. The optimal capacity coordination of ST and UPFC is derived in detail, and the control strategy of EHPFC is optimized. The steady-state and transient characteristics of EHPFC and UPFC for tidal current regulation are analyzed. The performance of EHPFC on the power flow of IEEE 14-node complex ring network is studied by using PSD-BPA software. The hardware experiment model of the transmission power flow of the double-ended system is established, and the simulation experiment of EHPFC is carried out. Simulation and experimental results show that EHPFC can achieve the same power flow control capability as UPFC at lower cost, and make up the problem that shortcomings of ST cannot be adjusted for continuous power flow, and verify the performance of EHPFC control flow.
