Abstract

Shunt active power filter (APF) has become the most effective tool for harmonic control in the industrial field because of its excellent performance. But in the field operation of APF is very complex, all kinds of interference factors of certainty and uncertainty always exist, the reliable operation of the device has a very serious harm. In this paper, an accurate mathematical model of APF in abc coordinates is established; By means of equivalent transformation, the parameters perturbation of the model are transformed into a part of periodic disturbance; the robust current control of APF is realized by the combination of repetitive control and passive control, the repetitive control compensates period disturbance, the passive control ensures the convergence of the repetitive control, and the effect of the aperiodic disturbance is suppressed. The accuracy of the mathematical model is verified by the simulation and engineering application. The control algorithm is simple and the practical engineering value is high
