Selective Three-Phase Current Reference Generation Using Multi-Resonant Method For Shunt Active Power Filter

Abstract

This paper proposes the application of an accurate, fast and stable method to be used by the control systems in the selective compensation of harmonic currents in three phase systems susceptible to frequency changes and phase jumps. This application is based on a MSOGI-FLL (Multiple Second Order Generalized Integrators - Frequency Locked Loop) method, which is composed of multiple double adaptive filters called "Dual Second Order Generalized Integrators" (DSOGI) coupled to the frequency detector entitled "Frequency Locked Loop" (FLL) which keeps the set synchronized, even in abnormal situations.
