| 摘 要： | 本文提出了一种ＵＰＦＣ物理模拟系统的设计方案。系统的核心部分－交流器采用多重化阶梯波趋近方法以改善输出波形，减少谐波，降低功耗。文中选用ＧＴＯ作变流元件并对其采取过流分级保护。在控制原理上使交流器的交流输出电压的幅值与相位分开控制以使控制易于实现。

| Abstract: | This paper introduces a design scheme of physical simulation system for the Unified Power Flow Controller(UPFC).Converters are the main components of this system and the multiple step wave approximation method is applied to improve the output waveform,diminish harmonics and reduce power loss.In this paper,the gate turn off(GTO) is used as a conversion element,it also adopts overcurent grading protection.It makes the control of amplitude and phase independent for output AC voltage of the conveters,in this way the control is easily realized. |
