Claim:
1. A method of restoring power in a power distribution network having a plurality of power sources, a plurality of loading zones, a plurality of switching devices interconnected between the plurality of power sources and the plurality of loading zones, an intelligent electronic device associated with each of the plurality of switching devices to control the switching devices, and a power restoration controller in communication with the intelligent electronic devices, the method comprising: isolating the loading zone that is in a faulted state; identifying one or more un-served load networks including loading zones downstream from the loading zone in a faulted state; restoring power to each un-served load network from a single power source; opening the switching device or switching devices that separate each un-served load network into two or more sub-networks if no single power source is capable of restoring power to the un-served load network; and restoring power to each of said sub-networks from a single power source, until the source capacity is exhausted or switching device loading capacity is violated.
