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.
A method for analysing the electric consumption of a plurality of electric household equipment operated on a consumption site, by filtering a load curve representing the electric consumption of said household equipment as a function of time, comprising the following steps:
A method according to 2, characterised in that the step of restoration consists in restoring, for each piece of household equipment, the complete or quasi-complete set of the power variation cycles for this piece of household equipment between the turning on and off thereof, by chronologically integrating in the set of the valid cycles of such piece of household equipment, cycles selected from the set of provisionally rejected cycles, with such selection being made using criteria and thresholds resulting from the step of learning.
A method according to any one of the preceding claims, characterised in that the set of predefined class of household equipment includes at least one of the classes among the following ones:
A method according to one of the preceding claims, characterised in that the digitized load curve is successively filtered using a specific algorithm for each class of household equipment, and in that the succession of said algorithms is sequenced.
A method according to any one of the preceding claims, characterised in that the steps of acquisition of the load curve and of filtering the load curve are carried out locally on the consumption site.
A processing device intended to be connected to the electric supply line of a consumption site, characterised in that it includes software able to implement the method according to any one of the preceding claims.
