| Abstract |
This paper presents the control circuit of a three-phase four-wire shunt active power filter with neutral current compensation based on the extension of instantaneous active and reactive curernt component Id-Iq method. The active power filter presented aims to compensate current harmonics of positive and negative sequence including the fundamental current of negative sequence and also all the zero sequence current harmonics. Therefore, acts as an harmonic, unbalanced and neutral current compensator. The control method used has an excellent harmonic compensation performance and presents the advantage of being frequency-independant. The neutral current compensation is achieved using a 4-leg voltage source converter controlled with a space vector technique. The DC voltage regulation system is analysed and its synthesis is performed. Simulation results are presented to show the stability of the voltage regulation system and to highlight the current compensation performance. |
