A Shunt Active Filter Based on Voltage Detection for Harmonic Filtering and Resonance Suppression

Abstract:

In most occasions shunt APFs and capacitors used for power factor correction exist simultaneously in the distribution network for saving costs. Ideally, APFs are used for harmonics filtering and capacitors are used for power factor correction. However, traditional control methods of APF have potential risk of resonance, affecting the stability and the effect of harmonic compensation, if the detected current contains capacitive current. This paper proposes a new control method based on voltage detection of point of common Coupling(PCC). Theoretical analysis and simulation demonstrate the new control method has functions of resonance suppression and harmonic filtering
