IEC 61850-90-12 “Wide Area Network Engineering Guidelines”

The first draft Technical Report (TR) for the future IEC TR 61850-90-12 has been published the other day (57/1536/DTR):

IEC 61850-90-12 TR: Communication networks and systems for power utility automation - Part 90-12: Wide area network engineering guidelines

Voting on this 202 page draft closes 2015-03-13

Wide area networks comprise in this context optical, radio, power line carrier, copper physical layers, with many topologies like rings, trees, and meshed networks, using different protocols (SDH, IP, MPLS, ...), data traffic (packet switching, TDM), and for a variety of applications (protection, SCADA, voice, video, …) for applications: between substations, between substations and control centers, and between control centers. One crucial aspect relates to protection data transmission via GOOSE, and the multicast data exchange of large amounts of sampled values (SV).

The list of normative references is quite long: some 150 documents are listed. Some examples are:

• IEEE 802.1ag, IEEE standards for local and metropolitan area network; Virtual Bridged Local Area Networks Amendment 5: Connectivity Fault Management)
• IEEE 802.1ah, IEEE standards for local and metropolitan area network; Provider Backbone Bridges
• IEEE 802.1Qay, Provider Backbone Bridge Traffic Engineering
• IEEE 802.1x, Port-based Network Access Control
• ITU-T G.0774-04: Synchronous Digital Hierarchy (SDH) - Management of the sub network connection protection for the network element view.
• RFC 3261, SIP: Session Initiation Protocol
• RFC 3376, Internet Group Management Protocol, Version 3

The list of abbreviations comprises some 300 terms from AAA (Authentication, Authorization and Accounting (security)) to ZBFW (Zone-Based Firewall).

The utilities all over have to get prepared for the huge amount of information to be shared on many different levels from switch gears all the way up to control centers … for many applications. You have to expect that the content of the IEC 61850-90-12 is a MUST reading for utility experts.

You could find a report that shows the importance of this part to a large utility:

IEC 61850-90-4 Network Engineering – Just Published

IEC just published a crucial document on network engineering:

IEC/TR 61850-90-4 ed1.0
Communication networks and systems for power utility automation -
Part 90-4: Network engineering guidelines

Congratulation to the editors of this great technical report – worth to study in detail!

IEC/TR 61850-90-4:2013 is intended for an audience familiar with network communication and/or IEC 61850-based systems and particularly for substation protection and control equipment vendors, network equipment vendors and system integrators. This Technical Report focuses on engineering a local area network focused on the requirements of IEC 61850-based substation automation. It outlines the advantages and disadvantages of different approaches to network topology, redundancy, clock synchronization, etc. so that the network designer can make educated decisions. In addition, this report outlines possible improvements to both substation automation and networking equipment. This Technical Report addresses the most critical aspects of IEC 61850, such as protection related to tripping over the network. This Technical Report addresses in particular the multicast data transfer of large volumes of sampled values from merging units. It also considers the high precision clock synchronization and "seamless" guaranteed transport of data across the network under failure conditions that is central to the process bus concept.

This 250+ page report could be used as a compendium of solutions for the various applications found in power automation systems. The communication infrastructure is one of the crucial aspects of the future energy delivery system – in the electric power world, gas delivery, heating and cooling systems as well as in E-Mobility. The recommendations given in this new part of IEC 61850 could be applied in many application domains even outside the energy world.

As you may have seen, network infrastructure vendors like MOXA and Kyland have integrated IEC 61850/MMS in their infrastructure.

IEC 61850 together with IEC 61400-25 and IEC 62351 provides a complete suite of standards for automation – even the title restricts the scope to power utility automation. This restriction is just toner on the paper! Almost all definitions in these standards can be used in many other domains. The communication stack (including object dictionary, ACSI, MMS, TCP/IP, Ethernet, … most of SCL) are completely independent of the electrical world.
