IEC 61850 communication based distance protection

IEC 61850 is the standard for communication substation which determines new applications of protection based on peer-to-peer communications between multifunctional protection devices (IEDs). The GOOSE messages (Generic Object Oriented Substation Event) can be used to replace the hard wired control signals exchanged between IEDs for interlocking and protection purposes. The idea is that the implementation of high-speed peer-to-peer communications should be equal or better than what is achievable by existing technology. The paper focus on using IEC 61850 based protection relays and on possibility of modeling of this processes in Matlab.
