Implementación de un tablero de comunicación con RTU SAITEL-DP de Schneider-Electric para interoperabilidad de IEDs en subestaciones

Abstract

This project aims to design, implement, and validate a control panel based on a Remote Terminal Unit (RTU), intended for the integration and testing of modern digital power protection systems. The main hypothesis states that a properly designed RTU panel, integrated with real devices and real-time simulation, allows the safe and early verification of protection behavior prior to commissioning in actual power systems. The justification of the project is based on the need to strengthen testing, supervision, and technical training processes for modern electrical protection schemes. The project development was carried out through the construction and integration of the RTU panel as the central element of the system, incorporating digital protection relays, communication interfaces, and a real-time simulator. Standardized communication protocols such as IEC 61850 were used, along with configuration and SCADA-type visualization tools. In addition, secondary injection techniques and electrical signal simulation were applied, following international technical standards. The results demonstrated the correct operation of the RTU panel, interoperability among the connected devices, and reliable real-time monitoring of statuses, alarms, and events. Finally, it is concluded that the implemented RTU panel represents an effective solution for the comprehensive validation of electrical protection systems, reducing operational risks and improving testing and technical training processes.
