INDUSTRY DRIVERS AND CHALLENGES
• Major grid transformation with the increased penetration of distributed and renewable energy resources, advanced metering, distributed control and automation, multiservice networks, among others.
• Increase of distributed generation is tending towards a lack of visibility and control at distribution level.
• Communication flow models have largely followed a one-way power delivery flow from generation to consumer.
• Most communication networks consist of multiple point-to-point circuits connecting substations to control centers for SCADA and EMS applications, and point-to-point circuits between substations for protection applications.

THE FUTURE GRIDE WIDE AREA NETWORK
• Electrical grids are shifting to an any-to-any power delivery model.

TELEPROTECTION OVER PACKET NETWORKS
Stringent requirements• Network Latency expected to be 4~16ms• Tolerable jitter depends on the protection relay vendor and
is typically in the range of 0.25 – 1.0 milliseconds• Relay attachment requirements: C37.94, E1/T1, X.21, E&M,
RS422, and recently Ethernet• Transport emulation: CESoPSN, SATOP and EoMPLS.• Frequency synchronisation: Sync-E, 1588 PTP.• Traffic Engineering

CONCLUSIONS INDIA 2013
• Power industry is seeing a shift in WAN design from TDM to packet based networks
• Utilities have been deploying MPLS and other packet based networks in large scale for some time.
• Successful implementation require careful consideration and planning
