Design and Commissioning of a Massive IEC61850 Multivendor Substation Automation Project: A twisted Path

Abstract

Technologies, such as IEC61850, introduce the need for a different engineering approach to electrical protection networks (EPN). Traditional telecommunication networks transporting information, require a new approach in design and architecture capable of responding to these emerging technologies.

These new protection networks have very precise requirements, such as GOOSE messages, in which a time greater than 3 ms is not allowed between the moment an event occurs and a protection signal is received.

This is why factors such as performance, reliability, redundancy, and cybersecurity are elements that become relevant when defining the network architecture and telecommunication protocols to use.
