This paper proposes a distributed computing architecture for protection functions within a digital substation,in order to achieve data redundancy,functional redundancy and functional coordination.This can be realized primarily due to the advances in digital and communications technology within a substation,particularly the process bus which allows data sharing between Intelligent Electronic Devices (IEDs).Results of backup protection investigation,using redundant information both within the substation and on a wide area basis,are then presented.A campus microgrid protection scheme was used as a test case to demonstrate the concept of protection using shared information.Finally,the paper proposes a multi-agent system as a simulation platform,which can be used to further demonstrate some of these concepts.
