This paper arrives at a method of harmonic and reactive current real-time detection applied on active power filter based on the three-phase circuit instantaneous reactive power theory. With Matlab simulation software, a research on simulation of harmonic detection means is carried out, and an analysis of the simulation result is presented. The result indicates: the harmonic detection means based on instantaneous reactive power theory can detect harmonic and reactive component in three-phase current precisely and real-time, to supply reliable harmonic and reactive current for harmonic restraint and reactive power compensation. It could provide reliable indicator parameters for research and development of active power filter.

The performance comparison of Sliding Mode (SM) control and instantaneous reactive power theory (PQ) control for three-phase Active Power Filter (APF) is presented. Algorithms for SM and PQ techniques were developed and used in the control of APF to shunt harmonics due to non-linear loads from the power grid. Total Harmonic Distortion (THD) was used for performance verification. The PQ control reduced the THD value, on average, from 29.84% to 4.937% while the SM control reduced the THD value, on average, from 29.84% to 5.27%. The results obtained show that PQ control offered slightly better performance in terms of reduced THD than the SM control even though the implementation of SM was less complex due to the use of programmable chips. In addition, the SM control recovered faster from transient disturbances than the PQ algorithm. Both results are, however, within the conformity limit of the IEEE standard and have proven to be good for harmonic mitigation. MATLAB/Simulink 2018 version was used as the simulation tool.
