Patent ID: 8000910

Claim:
A method of automatically recommending modifications to improve voltage regulation in an electrical system including a plurality of intelligent electronic devices (IEDs), comprising: determining a hierarchy of said electrical system, said hierarchy indicating how said plurality of IEDs are linked to one another in said electrical system; receiving from at least some of said plurality of IEDs respective voltage data indicative of at least one characteristic of a measured voltage; aligning or pseudo-aligning temporally said respective voltage data in mutual temporal context to produce aligned voltage data; analyzing said aligned voltage data to automatically determine at least one anomalous voltage condition present in said electrical system; based on at least said automatically determined hierarchy, automatically identifying at least one source of said anomalous voltage condition; and storing recommendation data in a memory, said recommendation data indicating a modification associated with said at least one source for ameliorating or eliminating said at least one anomalous voltage condition.
