The Portuguese transmission system operator REN continues to trust on Efacec Automation products and solutions. Last November, a new reference was added to the Efacec Automation portfolio, being successfully concluded the installation of automation system featuring protection and control in the Feira transmission substation (400/60 kV).

The Feira substation is integrated in the REN transmission network in the north of Portugal, with one-and-a-half circuit breaker layout topology for 400 kV, two transformers of 400/60 kV, five 60 kV lines and one bus-bar of 60 kV.

The supply, turn-key type, included project, configuration, test and installation supervision and commissioning of the automation system, based on the CLP 500SAS platform, integrating protection relays from Efacec and third parties.

The communication at substation level was implemented over IEC 61850 international standard. The substation system communicates with SCADA remote system located in the REN dispatch is performed over IEC 60870-5-101 protocol.

This project confirms, ones again, REN’s preference in Efacec solutions and services. Furthermore, at the same period of time two other projects, regarding new additions of 60 kV bays, were concluded. The substations, object of the expansions, were Bodiosa (400/60 kV) and Mourisca (220/60 kV), both already working with Efacec’s automation systems.
