摘要
Unbalance and harmonics are two major distortions in the three-phase distribution systems. In this paper new loss coefficients describing correlation between power losses due to unbalance and voltage unbalance in the distribution system, are introduced. The loss coefficients enable fast evaluation of unbalance losses in real life distribution systems by using available voltage data obtained from measurements in the field. For loss analysis a general power flow algorithm for three-phase four-wire radial distribution networks, based on backward-forward technique, is applied. Results obtained from several case studies using medium and low voltage test feeders with unbalanced load, are presented and discussed Copyright (C) 2008 Praise Worthy Prize S.r.l. - All rights reserved.
