Automatic Network Device Electrical Phase Identification

摘要

Techniques detect an electrical phase used by electrical network devices (e.g., a transformer, electrical meter, etc.). Voltage measurement data is obtained, such as from electrical meters. The voltage measurement data may be associated with a timestamp, and may be made at intervals over a period of time. Voltage changes may be calculated using the voltage measurement data. In an example, the voltage change is a difference determined between sequential voltage measurements. In some instances, voltage changes data is removed if it exceeds a threshold. An initial classification of network devices (e.g., randomly or by assumed electrical phase) is determined. A clustering technique (e.g., k-means) is applied, wherein the classification is updated in a manner that segregates the network devices according to actual electrical phase.

1. A method, comprising:
under control of one or more processors configured with executable instructions: obtaining voltage measurement data; calculating voltage change data using the obtained voltage measurement data; excluding voltage change data from among the calculated voltage change data that are outside a threshold range; configuring an initial classification of network devices; and iteratively updating the initial classification according to a clustering technique acting on the calculated voltage changes, thereby segregating the network devices according to electrical phase.
