Patent ID: 8825416

Claim:
A computer program product for phase determination in an electricity grid comprising: a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising: computer readable program code configured to access power consumption measurements derived from a supply electricity grid device that supplies power at a plurality of phases; computer readable program code configured to access power consumption measurements derived from a set of demand electricity grid devices connected in the electricity grid to the supply electricity grid device; computer readable program code configured to determine a phase of at least one demand electricity grid device in the set of demand electricity grid devices via: measuring, for a set of different time intervals over a series of time intervals, a total power consumed from the supply electricity grid device and power consumed individually by ones in the set of demand electricity grid devices; identifying the set of time intervals for which said measuring is performed; thereupon comparing the total power consumed from the supply electricity grid device with the power consumed individually by ones in the set of demand electricity grid devices with respect to the series of time intervals in total, using measurements from the set of different time intervals in the series; and thereupon determining a phase of at least one demand electricity grid device in the set of demand electricity grid devices, via employing calculations from said measuring and comparing steps; and computer readable program code configured to output the determined phase for at least one demand electricity grid device in the set of demand electricity grid devices.
