Ethernet
in Substation Automation Applications
This paper looks at the key issues and requirements for Ethernet
in the substation environment and for substation automation
applications requiring real-time performance. Specific topics
addressed are: EMI phenomena and atmospheric conditions in
substations which can affect network performance, new standards
introduced by the IEC and IEEE that establish new EMI and
environmental requirements specifically for communications networks
(i.e. Ethernet) in substations, critical Layer-2 features of modern
Ethernet switching hubs (i.e. switches) which enhance real-time
deterministic performance as well as fault tolerant loop
architectures and network redundancy.

Zero-Packet-Loss™
in the Substation
This paper explores the emerging trends of using the network to
perform mission critical real-time control applications, the new IEC
and IEEE standards for communications systems and networking
equipment in the substation, and the reasons/needs for
Zero-Packet-Loss™ in the substation.

The
Need for "Substation Hardened" Ethernet Switches
What Does It Mean to be ‚Substation Hardened™? This paper
explores this question in light of the special issues of substation
networking and new IEC & IEEE standards.

A
Comparison of Dispersed Topologies for Ethernet
The trend for automation and control networks in various industries
is to use Ethernet as the physical layer. This leverages a vast
array of both networking equipment and end devices. However,
deploying a real-time control Ethernet network in a geographically
dispersed area has a unique set of challenges. When the distance
between end stations is many kilometers, the network is still
logically a LAN, but physically is anything but local. Cabling costs
can be significant in such a network; choosing a topology that
minimizes these costs yet provides for a robust, fault tolerant
network is more difficult. This paper compares several different
topologies that address these needs.

Rapid
Spanning Tree in Industrial Networks
This paper discusses the application of Rapid Spanning Tree to the
construction of robust industrial networks. It is intended for
networking professionals wishing to better understand the operation
of the Rapid Spanning Tree Protocol (802.1w). |
