摘要：

Advanced metering infrastructure (AMI) offers utilities new ways to model and analyze distribution circuits. Results from two circuits introduce a new method to identify phasing of transformers and single-phase taps using voltage and kilowatt-hour measurements from AMI. In addition to phase identification, we show how to use the same approach to create or check meter-to-transformer mappings. These algorithms are based on linear regression and basic voltage drop relationships. With this approach, secondary connectivity and impedance models can be auto generated. In addition, detection of unmetered load appears possible. Also demonstrated is use of AMI to estimate primary-side voltage profiles.
