PREDICTIVE STRUCTURE FOR CURRENT REFERENCE GENERATION OF ACTIVE POWER FILTER

Tomislav Kilić, Stanko Milun

Abstract

The shunt active power filters are used to attenuate the harmonic currents in power systems by injecting equal but opposite compensating currents. Successful control of the active filters requires an accurate current reference. In this paper the current reference determination based on predictive filtering structure is presented. Current reference is obtained by taking the difference of load current and its fundamental harmonic. For fundamental harmonic determination with no time delay a combination of digital predictive filter and low pass filter is used.
