In this paper, the impuissance of traditional ip-iq method in reactive power compensation applications under nonideal mains voltages is illustrated first, and then a novel current reference calculation method for Shunt Active Power Filter (SAPF) based on p-q transformation is proposed. By means of the proposed method, the positive sequence fundamental active current component of the load current can be isolated under distorted and/or unbalanced mains voltages, which makes SAPF be capable of harmonic cancellation and reactive power compensation at the same time under nonideal mains voltages. The effectiveness of the new proposed method is mathematically studied and verified by computer simulation under ideal and nonideal mains voltages.
