PERFORMANCE IMPROVEMENT SYSTEM APPLIED TO NON-INTRUSIVE ELECTRICAL-LOAD MONITORING

摘要

A system (1) applied to non-invasive electrical load monitoring, is provided with: a metering unit (2), coupled to a power line (3) connected to a building (4) where a plurality of electrical loads (5) are located, configured to measure one or more electrical quantities on the power line (3) associated with the consumption of the electrical loads (5), so as to provide an associated aggregated consumption signal (S_c); and a load disaggregation unit (6), operatively coupled to the metering unit (2) so as to process the aggregated consumption signal (S_c) by means of an electrical load disaggregation algorithm. A detection unit (8) is operatively coupled to the load disaggregation unit (6), so as to detect significant variations on the power line (3) and cause the load disaggregation unit (6) to perform sampling and processing of the aggregated consumption signal (Sc) by means of the electrical load disaggregation algorithm mainly at time intervals in which said significant variations occur.
