Three-phase load flow [PDF]

open access: yesZbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2011
This paper presents a method for calculating three-phase load flow and voltage conditions in radial distribution systems with unbalanced loads. Asymmetries present in the distribution networks are the result of the unbalanced load and inductive and ...
