E-REDES is testing Self-Healing solutions in underground and overhead medium voltage distribution networks.
This project seeks to develop and test the evolution of the FLISR (Fault Location, Isolation and Service Restoration) and coordination of protections (IEC 61850 R-Goose) architectural models, aimed at:
- Increased network operation efficiency, through fast detection, fault isolation and network reconfiguration, fully automated (reduction of operation time associated with events and non-distributed energy).
- Improve quality of service indicators, namely SAIDI, SAIFI, voltage dips, among others. With this system it should be possible to isolate the fault and re-feed the grid autonomously.
In order to implement these projects, it was necessary to involve different areas of knowledge with a view to digitalizing, sensing and automating the distribution network’s operation. The project team, comprising E-REDES members, among other challenges, integrated a unique solution in Portugal without compromising normal business processes and with the strong involvement of the partners EFACEC (Overhead HS) and SIEMENS (Underground HS).
