ELECTRICAL LOAD IDENTIFICATION USING SYSTEM LINE VOLTAGE

摘要

Methods and systems may provide for receiving a set of voltage samples corresponding to a line voltage of a leg in an electrical system and conducting a time domain analysis to identify one or more loads in the electrical system. Additionally, the time domain analysis may be used to identify one or more loads in the electrical system. In one example, conducting the time domain analysis involves classifying events with respect to cross correlation, shape magnitude, transient amplitude, transient duration, run delta and/or standard deviation.

1. A load classification system comprising:
a sensor coupled to a leg in an electrical system, the sensor to generate a set of voltage samples corresponding to a line voltage of the leg; a front end module to receive the set of voltage samples; and a time domain module to conduct a time domain analysis of the set of voltage samples and use the time domain analysis to identify one or more loads in the electrical system, wherein the time domain module includes,
an event detector to detect an event with respect to the one or more loads; andan event classifier to classify the event with respect to one or more of a cross correlation, a shape magnitude, a transient amplitude, a transient duration, a run delta or a standard deviation.
