Power distribution virtual networking

Abstract

An electrical distribution system includes a plurality of electrical substations. Each of the electrical substations includes a plurality of intelligent electronic devices (IEDs), and a communications network interconnecting the plurality of IEDs at that substation. The communications networks at the plurality of substations are configured as at least one virtual network spanning multiple ones of the plurality of electrical substations, and interconnecting at least some of the IEDs within the multiple ones of the plurality of electrical substations, and so that delays experience by messages on the at least one virtual network are below a defined threshold. The virtual networks may be reconfigured when/if the threshold is not met.
