An automated integrated monitoring (IM) algorithm that automatically puts
data from a utility monitoring system into context by temporally aligning
the data to a common reference point and by identifying the location of
each monitoring device in a hierarchy relative to other devices.
Frequency variation data is received from all meters. The data is
automatically aligned to a common reference point, such as a precise zero
crossing, using a cross-correlation algorithm to determine the time delay
at which the data is most correlated. Once the data is aligned, power
data is received from all meters in a hierarchy, and the monitoring
system layout is auto-learned using a correlation algorithm to determine
which two meters are most likely correlated with one another based upon
their historical power readings. Once the layout is complete, additional
decisions regarding hardware and software configuration can automatically
be made by the IM algorithm.
