FEEDER SIMPLIFICATIONS FOR DISTRIBUTION-SYSTEM ANALYSIS

Three bilateral feeder models have been developed in this paper. These models are formed on the assumption that a complex feeder can be simp lified into an equivalent representation by simulating either the feed er line losses, the feeder voltage drop or both accurately. Bilateral models allow calculations to be performed easily regardless of the dir ection of power flow in the feeder. Furthermore, the power factor of e ach individual load has been taken into account in the developing proc ess. This implies less compromise and hence better accuracy. The propo sed methods will be presented in detail later in this paper and their accuracies compared using a sample feeder. (C) 1997 Elsevier Science S .A.
