摘    要:论文通过开关函数建模法确定统一潮流控制器(UPFC)的数学模型;在park变换的基础上,基于预测电流设计UPFC的d-q轴解耦控制方案。论文利用电压空间矢量脉宽调制法推导出UPFC各桥臂电力电子器件的开关状态。考虑到UPFC中间直流电容上电压控制的重要性,论文在传统PID控制的基础上,设计模糊自适应PID控制策略;MATLAB仿真结果表明,控制方案能有效地提高直流电容上电压的稳定性,改善功率波形,取得了类似扩大电容容量后的效果。系统可供同类设计参考。

关 键 词:统一潮流控制器  数学模型  UPFC  控制方法  逆变器  解耦控制  柔性交流输电系统

Abstract:This paper presents a mathematical model of unified power flow controller based on switch function; Based on park transformation, it designs a decoupled control scheme of UPFC in d and q-axis with the utilization of predictive current. It deduces the state of each power electronics device in UPFC by means of the voltage space vector pulse width modulation method. Considering the importance of capacitor voltage control of UPFC, it puts forward a fuzzy self-adaptive PID control strategy comparing with the traditional PID control method. MATLAB simulation program indicates that it can enhance the stability of the capacitor voltage and power flow. It is similar to enlarge the capacity of the capacitor. The whole control scheme can be referred by other similar control system.
Keywords:Switch function  Unified power flow controller  Voltage space vector pulse width modulation  Decoupled con-trol  Fuzzy self-adaptive PID
