| 摘 要： | 分内部控制和外部控制2部分对统一潮流控制器(UPFC)进行控制器设计.内部控制采用SVPWM控制,负责提供UPFC串、并联侧电压源逆变器的触发信号,并采用一种改进的相位求解方法解决了期望输出电压矢量相位计算过程中的数值溢出问题.外部控制采用在全论域范围内带有自调整因子的变间距模糊交互控制.负责产生UPFC串、并联侧逆变器所需的控制矢量.运用Matlab仿真工具对含UPFC的单机无穷大系统进行了仿真研究.仿真结果表明所设计的UPFC可以有效地控制线路潮流、节点电压和UPFC直流侧电容电压.并且具有响应速度快、超调小、控制精度高、鲁棒性强的优点.

| Abstract: | UPFC(Unified Power Flow Controller) is designed with internal and external control strategies.SVPWM(Space Vector Pulse Width Modulation) is applied in the internal control strategy to provide the trigger signals for the voltage source inverter at serial or shunt side,which adopts an improved phase solution to resolve the numerical overflow during the calculation of the expected output voltage vector phase.Variable interval fuzzy mutual control with self-adjusting factor is applied in the external control st... |
