摘　　要：文中用两个统一格式的背靠背逆变器实现了统一潮流控制器物理模型，开关元件采用绝缘栅双极型晶闸管构成的智能功率模块。统一潮流控制器的控制系统包含两个部分：双桥协调控制部分和两路完全相同的幅值、频率、相角控制部分。控制系统的硬件实现中采用模拟和数字相结合的方法来产生所需的控制信号；软件实现采用模块化的设计方法。针对谐波问题在装置中引入了ＬＣ滤波器。物理仿真实验结果表明本装置达到了控制性能要求，证明了统一潮流控制器对电网调控的有效性。The prototype of UPFC(unified power flow controller) is realized by using two identical “back to back” converters, in which the switch components are IPMs (intelligent power modules) consisting of IGBTs(insulated gate bipolar thyristors). The control system of UPFC includes two parts: coordinated control and “amplitude, frequency, phase” control. In the realization of the control system, the control signals are produced by combination of analog and digital methods, and the software is designed by modulization. To counter the harmonics problem, the LC filter is introduced into the prototype. The experimental results indicate that this prototype is satisfied for the control requests of UPFC, and effective to the control of power networks.
