摘要
为提高有源电力滤波器(APF)的谐波补偿性能,将LCL输出滤波器用作APF输出滤波器。建立了三相有源电力滤波器的空间电压矢量模型。利用有源电力滤波器的空间电压矢量模型给出了满足APF快速跟踪性能的输出滤波感取值范围。详细讨论了LCL滤波器各参数对输出滤波器性能的影响,提出了LCL输出滤波器的设计方法,并且给出了一个设计实例。最后仿真和实验验证了本文所提方法的有效性。
To improve harmonic compensation performance and increase the capacity of active power filter(APF), the LCL-filter is used as an output filter for APF. The space voltage vector model of three-phase shunt active power filter is built. The range of the output filter inductance meeting the performance of fast-track harmonic current is proposed. The influence of element parameters on the filtering performance of LCL-filter is analyzed. The design method of LCL-filter is proposed and a practical design example of APF is given. Finally, the simulation and experimental verify the validity of the proposed method.
