Single-phase active impedance hybrid active power filter is design to mitigate harmonic and reactive caused by the ever-increasing nonlinear loads. Nonlinear loads have been increased in residential and commercial as well as industrial sectors. Single-phase nonlinear loads contribute a harmonics and low power factor for the power systems. Single-phase active impedance hybrid active power filter was investigated to actively adjust multiple active short circuits. The dominant load current harmonics are compensated due to its multiple short effects over the single-tuned LC filter. At the same time, the conservative power theory (CPT) base reactive current extraction method was applied to actively regulate the reactive power. The amount of the fundamental filter reactive current obtained from CPT determines the reactive power compensation. The results were analyzed and presented in collaboration with the MATLAB/Simulink environment and TMS320F28335 board. The active impedance and CPT based control achieved a harmonic compensation (from 65.96% to 3.20%) and power factor correction from 0.85 to 0.95. Therefore, the active impedance hybrid active power filter can be taken as a good candidate for harmonic and reactive compensation with extending the conventional hybrid active power filter (HAPF) into multiple active tuned filters. It has potential practical benefit to avoid regular field retuning the passive filter in the industry. Moreover, it can also apply for PQ compensation using the existing PPF.

基于单相有源阻抗的谐波和无功补偿

单相有源阻抗混合有源电力滤波器旨在减轻不断增加的非线性负载引起的谐波和无功。住宅和商业以及工业部门的非​​线性负载已经增加。单相非线性负载为电力系统带来谐波和低功率因数。研究了单相有源阻抗混合有源电力滤波器以主动调节多个有源短路。由于其对单调谐 LC 滤波器的多重短路效应，主要负载电流谐波得到补偿。同时，采用基于保守功率理论（CPT）的无功电流提取方法对无功功率进行主动调节。从 CPT 获得的基波滤波器无功电流量决定了无功功率补偿。与 MATLAB/Simulink 环境和 TMS320F28335 板协作分析并展示了结果。基于有源阻抗和 CPT 的控制实现了谐波补偿（从 65.96% 到 3.20%）和功率因数校正从 0.85 到 0.95。因此，有源阻抗混合有源电力滤波器可以作为谐波和无功补偿的良好候选，将传统的混合有源电力滤波器（HAPF）扩展为多个有源调谐滤波器。在工业中避免定期现场重新调谐无源滤波器具有潜在的实际好处。此外，它还可以使用现有的 PPF 申请 PQ 补偿。基于有源阻抗和 CPT 的控制实现了谐波补偿（从 65.96% 到 3.20%）和功率因数校正从 0.85 到 0.95。因此，有源阻抗混合有源电力滤波器可以作为谐波和无功补偿的良好候选，将传统的混合有源电力滤波器（HAPF）扩展为多个有源调谐滤波器。在工业中避免定期现场重新调谐无源滤波器具有潜在的实际好处。此外，它还可以使用现有的 PPF 申请 PQ 补偿。基于有源阻抗和 CPT 的控制实现了谐波补偿（从 65.96% 到 3.20%）和功率因数校正从 0.85 到 0.95。因此，有源阻抗混合有源电力滤波器可以作为谐波和无功补偿的良好候选，将传统的混合有源电力滤波器（HAPF）扩展为多个有源调谐滤波器。在工业中避免定期现场重新调谐无源滤波器具有潜在的实际好处。此外，它还可以使用现有的 PPF 申请 PQ 补偿。在工业中避免定期现场重新调谐无源滤波器具有潜在的实际好处。此外，它还可以使用现有的 PPF 申请 PQ 补偿。在工业中避免定期现场重新调谐无源滤波器具有潜在的实际好处。此外，它还可以使用现有的 PPF 申请 PQ 补偿。
