  2. 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.

  3. The future gride Wide Area Network • Electrical grids are shifting to an any-to-any power delivery model.

  4. AnArchitectural Approach

  5. 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

  6. Examples of Evolving Requirements • 61850 Edition 2 • Next Generation Energy Management Systems • Wide Area Monitoring, Control and Protection Schemes

  7. Network Design Principals • Determinism • Path selection control • Security • Resiliency • Quality of Service • Traffic Engineering • Ease of Operations • Timing and Synchronisation • Multiple Traffic Type Support

  8. ConclusionsIndia 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
