1. An electronic device configured to switchover power supplied from a primary source to an alternate source to maintain continuity of power supplied to a load bus, wherein the electronic device comprises one or more processors configured to:
identify availability of the alternate source using source monitoring in order to measure and calculate a tracking frequency for controlling a variable sampling interval of the one or more processors; obtain signal samples having associated time stamps from the primary source, the alternate source, and the load bus; store load bus signal samples and associated time stamps of the load bus into a variable length buffer; calculate a new time stamp for transferring to a fixed length buffer from a measured load bus signal frequency for applying a dual buffer sampling interval transfer to estimate a new sample value at the calculated new time stamp; store the new sample value and associated new time stamp into the fixed length buffer; determine a set of attributes from samples of the alternate source using the tracking frequency and fixed length buffer samples of a load bus supply, wherein the set of attributes comprise a magnitude, an angle, a frequency, a slip, an acceleration, or any combination thereof; and calculate supervising conditions to execute a source switchover signal when the primary source is unavailable based at least in part on comparing the set of load bus attributes to alternate source attributes at an estimated instance of switchover. |
