Abstract

This work presents a study of the effectiveness of the compensation impedance calculation methodology for the intrinsically unbalanced three-phase power distribution system (T2F). The calculation methodology in question is based on the Carson’s image method to obtain impedance values that, when arranged longitudinally and transversally to the system, equalize it in order to reduce voltage unbalance levels (%DT). The comparison of the effectiveness of the calculated compensation is performed through the proposal of a computational method to obtain the impedance values that equalize the system in order to completely eliminate the unbalance between the phases. This study shows that factors such as the value of impedances implemented and their arrangement in the system directly imply the results of %DT measured in the load coupled to the circuit.
