Diseño de un sistema de monitoreo con enfasis en pruebas de inyeccion de corriente para una RED de 9 barras bajo el estandar IEC61850

Abstract

The organizations that operate electrical systems and distribute this supply to different populations must keep each part of the electrical system stable. Therefore, in this study, the general objective was to design and simulate a monitoring procedure for a 9-bar electrical network, using SEL 751 relays in accordance with IEC61850 standard standards, with the purpose of measuring the electrical parameters of the branches of the bars and the operating status of the electrical system switches. For this purpose, the qualitative-quantitative, descriptive and field method was applied as the main method, where the ETAP system, Ómicron equipment, SEL 751 relays and Fluke 87V multimeter were used. The results evidenced in the study indicated the stability of the electrical system in question, with a power factor greater than 95% in each of the buses of the network in question, where the amperages and voltages detected in each of the buses of the 9-bar electrical network, were found at the same level, both in the simulation and current injection tests, corroborating high protection and high response capacity of the monitoring system to real fault events, evidencing compliance with the parameters electrical stipulated in the IEC61850 standard. In conclusion, the design and simulation of monitoring a 9-bus network, using SEL 751 relays under the IEC61850 standard, improved the system voltage stability.
