Implementação de um compensador ativo série para sistemas de distribuição

Abstract

This work presents a practical implementation of a Series Active Power Filter for Voltage Sags and Voltage Harmonics compensation. Aspects concerning equipment development and testing are also discussed. It is shown how a 13.8kV bus can be compensated, even using 220V low cost IGBTs. Problems of the proposed topology are shown as well their solutions. A contribution to the area, related to algorithms development for Active Power Filters, is also given. It is described a noise-tolerant algorithm, based on the traditional id-iq method. It is explained why traditional techniques are sensitive to noise and shows where the vulnerability is located. Simulation results are presented to compare the proposed method against the traditional. Experimental results are also shown.
