摘　　要：＂SEN＂变压器（ST）是目前功能最强的电磁式统一潮流控制器,但为了使其能具有更灵活的潮流调控能力和更大的电压输出范围的目的,在此装置结构基础上提出了一种新型拓扑结构的电磁式统一潮流控制器（EUPFC）。首先介绍了广东电网环网运行现状,然后提出EUPFC的拓扑结构及工作原理,研究了EUPFC对线路有功、无功潮流进行独立、灵活调节的作用。采用MATLAB/Simulink建模的方法对比分析EUPFC和ST应用于广东220 kV环网输电网络的潮流调控能力,结果表明EUPFC对环网线路负载率的改善效果比ST提高9%以上,线路输电极限比ST提高8%以上,EUPFC的潮流调控能力更强。最后,搭建出试验平台、研制10kV样机并进行了实验,试验证明EUPFC的无功潮流调控范围比ST多30%。仿真实验证明了所提拓扑结构的正确性和潮流调控的有效性。The ＂SEN＂ Transformer（ST） is the most powerful electromagnetic unified power flow controller; however, in order to achieve more flexible power flow regulation capability than ST, we proposed a new type of topology electromagnetic unified power flow controller（EUPFC）. Firstly, we introduced the operation status of the ring network of Guangdong Power Grid, proposed the topology and working principle of EUPFC, and studied the independent and flexible working mode of EUPFC to the active and reactive power flow of the line. Then, we used the MATLAB/Simulink modeling method to compare and analyze the power flow regulation capability of EUPFC and ST applied to the 220 kV ring transmission network of Guangdong Power Grid. The results show that the improvement effect of EUPFC on the load ratio of the ring network increases by more than 9%over that of ST, meanwhile, the transmission limit of the line is increased by more than 8%, so the power flow regulation ability of EUPFC is stronger. Finally, a test platform was built and 10 kV prototype was developed and tested. The experiments prove that the reactive power flow regulation range of EUPFC increases by 30% compared to ST. Simulation experiments demonstrate the correctness of the proposed topology and the effectiveness of power flow control.
