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.
