Abstract

This paper describes differences of two
approaches for voltage computation at the point of common
coupling (PCC) in three-phase low voltage (LV) systems.
The first approach is based on topology of three–wire threephase
system and the second one is based on four-wire
topology. The paper is aimed mainly for computation of
supply voltage variations and voltage unbalance due to
unsymmetrical loads. The presented method is suitable for
engineers engaged in power quality evaluation.
