Brazilian Utility CELPE upgrades SCADA, telemetry

CELPE, the Brazilian power utility in the state of Pernambuco, is now completing the second phase in the upgrade of its communications network by extending its digital backbone to the city of Serra Talhada, more than 250 miles from its corporate headquarters in Recife.

To accomplish this, CELPE acquired and installed fourteen Megaplex-4 multiservice access nodes manufactured by RAD, the international manufacturer of communications access solutions for power utilities.

The Megaplex units, a prime component of RAD's Service Assured Networking solution, were integrated into twelve CELPE sites, comprised of eleven substations and its main network core situated at its integrated operations center.

In the first phase of the project, which was completed about a year ago, CELPE replaced its old 2 Mbps PDH infrastructure with RAD’s Megaplex-2100 platform. In this way, the original optical transport network became a 155 Mbps Ethernet ring with central management of all legacy and new packet-switched Ethernet services. This enables the eventual migration to an all-packet infrastructure and the implementation of all Smart Grid compatible projects.

In addition to extending the optical network to Serra Talhada, which has 85,000 inhabitants, the new phase of the project and the deployment of the Megaplex-4 increases CELPE’s network speed from 155 Mbps to 1Gbps, and sets this higher speed as the standard for the company’s new projects.
