摘要: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.
