Estudio de las corrientes transitorias causadas por el arranque de motores trifásicos en la red de medio voltaje (13.8 KV), Cerro Pelado mediante la herramienta ATP DRAW

Abstract

This study deals with the analysis of transient currents generated during the starting of three-phase motors in the medium voltage network (13.8 kV) in the Cerro Pelado feeder using the ATP Draw simulation tool. Transient currents can produce significant disturbances in the stability and operation of the electrical system, so their study is essential to guarantee a reliable and safe electrical supply. Through ATP Draw simulation, different three-phase motor starting scenarios were modeled to evaluate the impact of these transient currents on the network. The results obtained allowed the identification of peak current levels and their duration, as well as the possible effects on the system components. The analysis revealed the importance of implementing adequate mitigation measures, such as coordination of protections and soft-start devices to reduce the adverse effects of transient currents on the network. Therefore, this study provides a solid basis for developing strategies to improve the reliability and operational efficiency of the medium voltage network in the Cerro Pelado feeder.
