Control de voltaje en redes de distribución mediante el uso de cambiadores de toma bajo carga empleando el software Open DSS

Abstract

The operation of an electrical system in the distribution stage leads to the management of different control variables, one of the most important being the voltage level in an unbalanced system, so that an inadequate control of the voltage can contravene the normal operation of the system. For this reason, the present research work is developed in order to establish voltage control through the use of on-load tap changers in unbalanced electrical distribution networks, whose modeling will be carried out to the IEEE type electrical system of 13 nodes using the OpenDSS software, the aforementioned network subject to different case studies in which variations in demand will occur and generation implementation will be distributed in the network, thus authorizing the evaluation of various electrical variables, including voltages, powers of distributed generation , supplements of regulating transformers, the results of which have made it possible to establish the quality indexes of the voltage level and the technical strategies that must be observed for the operation of this type of electrical systems, considering the cases and study scenarios proposed.
