Abstract
(EN)
A computer-implemented method for evaluating the energy consumption in an industrial plant, comprising: at a plurality of time instants, capturing with a plurality of sensors, sensor data from at least one level of the industrial plant, wherein said plurality of sensors comprises energy measuring sensors; from said sensor data, digitally obtaining a plurality of energy consumption curves xj, an energy consumption curve representing, along a certain time period T, discrete values of energy consumption corresponding to time intervals Δt into which said time period T is divided; from said energy consumption curves xj, applying a clustering algorithm for digitally computing a plurality of K energy consumption patterns Ck, wherein each energy consumption pattern Ckrepresents a set of energy consumption curves xjgrouped together according to a similarity metric, wherein each energy consumption pattern Ckcomprises discrete values of energy consumption corresponding to said time intervals Δt into which said time period T is divided; capturing data of the production achieved during said time period T at said at least one level of the industrial plant; calculating, for each energy consumption curve belonging to each pattern, the aggregated sum of the discrete values of energy consumption during said time period T, thus obtaining the aggregated energy consumption for each energy consumption curve during said time period T; digitally establishing a relationship between aggregated energy consumption for each energy consumption curve during said time period T and said captured data of production.
