چکیده
In order to detect grid harmonic and reactive current precisely and real time, this paper arrived at a method of harmonic and reactive current real-time detection applied to active power filter based on the three-phase circuit instantaneous reactive power theory. With Matlab simulation software, researches on simulation of harmonic detection means are 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 realtime and provide reliable harmonic and reactive current for harmonic restraint and reactive power compensation. Therefore, this method can provide reliable indicator parameters for researches and development of APF and SVC. Keywords-Instantaneous reactive power theory, harmonic current detection, simulation

In this paper, a novel control strategy for a Shunt Active Power Filter (shunt-APF) is proposed. In the proposed control strategy which is based on a new application of the instantaneous reactive power theory, the current injected by the shunt-APF is capable of compensation for the reactive component, the harmonic components and also unbalance of the load current. In this strategy, the shunt-AP...

This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...
