| 摘 要： | 提出了一种基于ip-iq谐波电流检测、模糊PI电流控制和空间矢量脉宽调制的三电平有源电力滤波器的控制方案;建立了三电平有源电力滤波器的数学模型,详细介绍了三电平有源电力滤波器直流侧电压稳定和中点电位平衡控制方法的具体实现。仿真和实验结果表明,采用该控制方案的三电平有源电力滤波器具有良好的谐波补偿效果,且能较好地稳定直流侧电压和电容中点电位。

| Abstract: | The paper proposed a control scheme of three-level active power filter based on ip-iq harmonic current detection,fuzzy PI current control and space vector pulse width modulation.It established a mathematical model of the three-level active power filter,and introduced concrete realization of control method of DC-side voltage stabilization and neutral-point potential balancing of the three-level active power filter.The simulation and experimental results show that the three-level active power filter controlled by the scheme has good effect of harmonic compensation,and can stabilize DC-side voltage and capacitance neutral-point potential well. |
