The invention relates to a non-intrusive load identification method with a self-learning ability and a smart electric meter, aiming to overcome the defect that existing non-intrusive load identification technology cannot realize self-learning. A metering core of the smart electric meter provides voltage and current sampling data; a load identification core intercepts transient variation and peripheral steady state data and calculates a load characteristic, and a load identification and load characteristic library is updated and modified; and a management module interacts with a user so as to determine uncertain identification results, and calculates electric appliance running data. The load identification method realizes self-learning; when a new electric appliance is added, the existing identification method is still usable; the characteristic library size is kept within a certain range; and load identification operation amount is within a certain range.
Description
technical field [0001] The invention belongs to the technical field of non-invasive load identification, and in particular relates to a non-invasive load identification smart electric energy meter with self-learning ability. Background technique [0002] "Non-intrusive load identification" is a technology that uses electrical appliance feature construction and pattern recognition technology to analyze the power consumption status of end-users of the power grid, and specifically refines it to each household appliance; [0003] With the development of this technology, it is on the agenda of the power supply department to explore and build a real-time, sensitive terminal power grid perception, interaction and application system, and to provide "customer-centric" high-quality new power supply services; Provide data support by grasping the actual electricity consumption of the user's household appliances, predicting the electricity consumption of the terminal grid in advance, and...
