| 摘 要： | 引入开关函数的概念,考虑了统一潮流控制器(UPFC)各相桥臂电力电子器件具体的开关状态以及三相电网电压的不平衡因素,建立了可反映UPFC装置内部开关特性和运行机理的UPFC暂态数学模型.该模型能够反映UPFC最终的输入控制量及输出量,并合理地设计了应用于该模型的电压空间矢量脉宽调制(SVPWM)控制方案.

| Abstract: | In this paper, a transient mathematical model of unified power flow controller is constructed by introducing the concept of switching function and considering the switching state of each power electronic device in unified power flow controller and the unbalance of three phase network voltage, which reflects the internal switching character and the operational mechanism. The final input controlled variables and output variables of UPFC are reflected. A voltage space vector pulse width modulation control scheme applied to the model is reasonably designed. |
