Abstract

APFs (Active Power Filters) are solid-state devices used to compensate nonlinear load harmonics and improve customer power quality. The selection of its designing parameters, especially the output inductance, affects its performance. The output inductance decides the reaction speed and compensation current of APF. By αβ transformation, the model of APF on αβ coordinates is erected. According to the mathematical analysis, the scope for output inductance selection in APF is determined. Within the range, optimal values are selected by simulation to make the total harmonic rate least. The calculated scope for output inductance selection effectively reduces the blindness in APF designing. Combined with values of other parameters in the system, the output inductance can be decided to improve the compensation performance.
