Propuesta de implementación de un sistema SCADA bajo la normativa IEC 61850 para la observación remota de la bahía de la subestación Porotillos

Abstract

The digitalization of electrical substations based on the IEC 61850 standard requires SCADA systems with high interoperability, speed, and reliability. This project develops and implements a SCADA system for the Porotillos energization bay, integrating Intelligent Electronic Devices (IEDs) through IEC 61850 communications and validating its performance through laboratory testing at Universidad Politécnica Salesiana. The methodology included the design of the communication architecture, the configuration of logical signals between IEDs, and their integration into the SCADA system for supervision and control. Functional tests were conducted under normal and fault conditions to verify correct signal transmission and protection response. The results confirmed effective communication and reliable system performance under simulated protection events. It is concluded that the implemented architecture meets the functional and operational requirements of a modern digital substation and provides a solid foundation for future improvements focused on redundancy and high availability.
