Diseño y desarrollo de un sistema SCADA para el monitoreo en tiempo real de un banco de pruebas de líneas de transmisión eléctrica

Abstract

The implementation of the SCADA system on the transmission line test bench validated the interoperability of its key components. The system successfully integrated the SACI ANG96, Siemens PAC3100, and PAC3200 network analyzers through the Modbus RTU communication protocol. The SEL-3530 controller, programmed with customized logic via AcSELerator RTAC, served as the core of the system, establishing a direct link between the Modbus addresses of the analyzers and the internal system variables. The HMI interface, developed using TIA Portal and WINCC software, was successful in enabling the visualization and supervision of the system. The implemented interface displayed real-time electrical parameters such as voltages, currents, powers, and respective power factors. Accurate operation was ensured by allowing individual access to each analyzer directly from the HMI. The system demonstrated stable and precise behavior in each of the different test configurations, which included short, medium, and long line connections. This performance validates its applicability in academic studies that contribute to the analysis of electrical phenomena and load imbalance. The project has a solid foundation that can continue to expand in the future, including the addition of historical data recording.
