摘要针对统一潮流控制器（UPFC）存在成本过高和“Sen”变压器（ST）不能连续可调的问题,对电磁混合式统一潮流控制器（HUPFC）进行了结构和控制策略优化。HUPFC由一个高容量的“ST”和一个小容量的UPFC串联组成,具有360°连续可调的电压输出能力。详细推导出ST不同绕组比例和抽头数量下的UPFC最小容量关系,分析了HUPFC中闭环控制策略。通过Matlab/Simulink对HUPFC调节电网电压与功率的静态和动态特性进行仿真。仿真结果证明了所提出方法的可行性与有效性。

Abstract：Aiming at the high installation and operation cost of the unified power flow controller (UPFC) and the discrete adjustment of “Sen” transformer (ST), the topology structure of the electromagnetic hybrid unified power flow controller is optimized in this paper. Electromagnetic hybrid UPFC (HUPFC) topology, consisting of a high-capacity ST and a small capacity UPFC, has been studied in this paper. HUPFC can adjust to the output voltage in 360° continuously. This text derives the relationship of UPFC minimum capacity in detail, analyze the close control strategy of HUPFC system and verify to the static and dynamic simulation characteristics of voltage and power control of HUPFC through Matlab/Simulink. Simulation results show that the proposed method is feasible and effective.

Key words： “Sen” transformer unified power flow controller electromagnetic hybrid unified power flow controller
