Title Three-phase positive and negative sequences estimator to generate current reference for selective active filters
Editor 10th MEDITERRANEAN CONFERENCE ON CONTROL AND AUTOMATION (MED 2002)
Keywords active power filters, harmonic distortion, positive and negative sequences
Abstract
This article deals with the on-line estimation of three-phase three-wire signal harmonics. It is performed in the d-q synchronous reference frame and exploits the Luenberger observer concept to isolate positive and negative sequences of each harmonic. This estimator is suitable to be implemented as reference generator for selective active power filters. Simulation and experimental results are presented.
