Abstract

The significant growth in the number of connections of distributed generation (DG) units in distribution networks increases the operational complexity of such networks. One of the complicating factors is the improper action of the DG protection against islanding using an undervoltage relay in the event of short-circuits in feeders adjacent to the generation connection. In this sense, this study investigates through computer simulation in which situations this undue actuation occurs and which circuit elements influence the occurrence or not of these actuations.
