Özet: In our days, parallel converters are used in many applications due to high performance, high reliability or high power. The presence of zero-sequence and negative sequence components of voltage and current harmonics creates many adverse effects in the power system. This paper presents an algorithm implemented in LabVIEW, which simulates the functioning of a three phase active filter. This application improves the functioning conditions of a three phase nonlinear and unbalanced load. Based on the symmetrical components method, the system described in this paper can generate the residual signals that must be removed. Application decomposes distorted and unbalanced current system in symmetrical components and shows their variations in time domain and in also in the phases diagrams.
