Shunt Active Power Filter

摘要: Shunt active power filters have been introduced as a way to overcome the quality problems caused by nonlinear and reactive loads [9, 14, 23]. These electronics devices are designed with goal of obtaining factor close 1 achieving current harmonics compensation [5, 6, 15]. The usual approaches 15] for control shunt based on two hierarchical loops: an inner one that assures desired outer in charge determining its required shape appropriate balance well. structure followed this Chapter is [7], which controller composed feedforward action provides very fast transient response, also feedback loop includes odd-harmonic repetitive yields closed-loop stability good harmonic correction performance. In turn, law appropriated computation amplitude sinusoidal network and, aiming at robustness improvement, combined including analytically tuned PI controller.
