Description: UTC Training Webinar: Protective Relaying over Packet Network including Leased Ethernet Services - A Case Study There is no doubt that today’s telecommunications infrastructure for
industrial industries, including mission-critical infrastructure such as
the power utilities, are migrating toward an all-packet-based transport
network. Today, the emerging trend for substation automation is a
“Smart Network” optimized for data networking and able to support multi-functional IEDs using packet-based switching communications. Most
importantly, protective relays and teleprotection devices using data
communications as part of their operating principles have very stringent
requirements with regard to latency and reliability. Providing that
channel over packet-based infrastructure including leased Ethernet
services poses a challenge for these existing devices that were designed
for direct fiber, T1/E1 or SONET/SDH networks. While there are several
solutions that are paving the way to modernize the substation
communications infrastructure, power utilities are looking for a path
forward that minimizes operational impact, requires little engineering,
and assures comparable security and high reliability for their
protection and SCADA system. This presentation explores the
modernization of substation automation. It outlines the major challenges
power utilities face as the substation communications infrastructure
migrates toward an all-packet-based network including the migration of
4-wire-audio leased-line services to Ethernet-leased services. It also
addresses the stringent requirements for Protective Relaying and SCADA
applications over packet-based networks, particularly over
publicly-leased Ethernet services. Finally, it presents in detail,
several case studies from several power utilities that have successfully
migrated their system protection and substation automation applications
to a packet-based communications network including leased Ethernet
services.
