摘要
The present invention relates to a method for analyzing the electricity consumption of a site provided with a plurality of electrical devices of different types, wherein the method comprises: periodically measuring the current and the voltage over at least one of the electrical phases upstream from the power supply network of the site; and processing a combination of digitized signals in order to determine the distribution of the consumption on the basis of at least some of the devices in accordance with a signature of each of the devices. The processing involves comparing the waveform of the measured current with a library of pre-saved signatures for each of the electrical devices. The signatures comprising at least one parameter based on the waveform of the supply voltage. The signature of each device is predetermined during a prior step that involves: applying, to each device, a predetermined series of power supply sequences with voltage signals, the waveform of which represents the waveforms observed on ordinary electrical facilities; and recording the current waveform resulting from the operation of said device. The invention also relates to a method for modeling a device for implementing the analysis method.
