SYSTEM AND METHOD FOR MANAGING POWER FEEDS THROUGH WAVEFORM MONITORING
First Claim
1. A system comprising:
- a data center configured to operate based on a supply of low-voltage power;
an electrical substation electrically coupled to the data center, the electrical substation comprising;
a transformer configured to step down high-voltage power into low-voltage power supplied to the data center, andat least one switching device configured to selectively route high-voltage power to the transformer from one of a primary utility power source and an alternate utility power source; and
a power waveform monitoring system configured to;
monitor at least a primary waveform associated with high-voltage power received from the primary utility power source for a first waveform pattern indicating potential interruption of high-voltage power received from the primary utility power source, andin response to identifying the first waveform pattern, direct the switching device to switch from selectively routing high-voltage power from the primary utility power source to selectively routing high-voltage power from the alternate utility power source, such that switching occurs prior to the interruption, and further such that operations of the data center are uninterrupted due to the switching.

Abstract
Managing power feeds includes monitoring a waveform of a high-voltage power feed supplied to an electrical load to detect potential interruption of the high-voltage power feed and switching to another power feed to supply power to the electrical load in response to identifying the waveform pattern. Monitoring a waveform includes processing the waveform to determine if one or more waveform patterns are present in the waveform. A waveform pattern indicates, by its presence in a waveform of a power feed, a power event associated with the power feed, and some waveform patterns indicate potential interruption of the power feed. Switching to another power feed in response to determining potential interruption of the power feed based on waveform monitoring enables an uninterrupted power supply.
