LOCATION MAPPING OF GRID DEVICES USING FEATURES OF PASSIVELY-OBSERVED CURRENT DISTURBANCES

摘要

A method of assessing an electrical grid includes measuring an electrical signal at downstream and upstream locations locations in the grid. The downstream locations include devices that receive electrical power from the grid. Based on measurements in the downstream locations, a downstream current profile is determined for the downstream locations. Based on measurements in at least one of the upstream locations, an upstream current profile is determined for the upstream locations. The downstream current profiles and the upstream current profiles have characteristics produced by at least one of the devices. For at least one of the devices, the downstream current profile is compared to one or more of the upstream current profiles. Based on the comparison, an electrical location is determined for the device. In some embodiments, a grid map is generated based on comparisons between upstream current profiles and downstream current profiles.
