Summary:The paper presents the results of the analysis of the power quality in the point of common coupling of an internal network of an industrial enterprise, following the recording of the energy parameters in the critical load interval. The equivalent load in the point of common coupling (PCC) consists mainly of nonlinear single-phase loads, which makes the phase powers to be strongly unbalanced. The recordings made and their processing highlighted the poor power quality and the need to identify an appropriate solution to improve the power quality. It was proposed to use a four-wire shunt active power filter (SAPF) with split filtering capacitor.
