摘要
分析了三电平有源电力滤波器(APF)主电路结构特点。采用基于瞬时无功功率理论的ip-iq法以及FFT法的APF谐波检测方法,针对三电平结构下基于空间电压矢量控制方法的实现原理进行了分析。给出了不同检测方法下直流侧电压的控制方案。最终的仿真以及实测结果验证了所设计的测量与控制方法的合理性。
This article analyzed the structure of three-level main circuit of active power filter（APF）. It uses is- ia method for the detection of total harmonic current and FFT method for the single and appointed order harmonic current . It analyzed the principle of control method based on SVPWM for three level structure. Also it gives the DC voltage control methods under different harmonic detection method. Finally, the results of simulation and actual experiment demonstrate the effectiveness of the designed detection and control method.
