METHOD AND DEVICE FOR FILTERING ELECTRICAL CONSUMPTION CURVES AND ALLOCATING CONSUMPTION TO CATEGORIES OF APPLIANCES

摘要

The invention relates to a method for analysing the electrical consumption of a plurality of electrical appliances operating on a consumption site, by filtering a demand curve representing the electrical consumption of said appliances according to time. Said method is characterised in that it comprises the following steps: before the filtering per se of the demand curve, the demand curve is recorded and digitalised in such a way as to obtain a demand curve digitalised by periods of time; a set of categories of appliances is defined, each category being defined by similar cycles of power variation according to the time; an algorithm is defined for each category of appliances, for filtering the demand curve for said category of appliances, said algorithm being able to extract the power variation cycles from the digitalised demand curve and to allocate the electrical consumption to said category of appliances; then during the filtering per se of the digitalised demand curve, the filtering algorithms for each category of appliance are used successively to identify and regroup the power variation cycles consumed by said electrical appliances, from the digitalised demand curve.
