The performance of the integrated power filter system composed of shunt passive filter and active filter connected in series in three-phase system has important influence on its practical application. In this paper, a theoretical analysis of this problem in the frequency domain is made. The effectiveness of the harmonic detection method based on instantaneous reactive power theory under three-phase asymmetry conditions is analyzed. A three-phase asymmetric power supply, asymmetric passive filter , Asymmetric load and other asymmetric conditions, the compensation strategy of integrated power filter system is proposed. The simulation and experimental results based on simulink based on MATL AB verify that the harmonic detection method based on instantaneous reactive power theory under the condition of three-phase asymmetry And the feasibility of the compensation strategy of the integrated power filter system proposed in this paper, and also points out the limitations of the integrated power filter system in the case of three-phase asymmetry
