Abstract

The invention discloses a non-intrusive load identification based subentry measuring smart electricity meter. The smart electricity meter includes a non-intrusive load identification module integratedin the smart electricity meter, wherein the non-intrusive load identification module can be printed on a main circuit board of the smart electricity meter or can be connected with the main circuit board of the smart electricity meter through a connector, and the non-intrusive load identification module is mounted in the meter box of the smart electricity meter or mounted in a reception cabin of asmart electricity meter module; the non-intrusive load identification module is used for identifying loads of different types mounted in a house, obtaining subentry measurement results of the different load types and outputting the corresponding subentry measurement results . According to the invention, non-intrusive load identification is integrated with a prior smart electricity meter, so thatprior smart electricity metering level is improved, richer electricity consumption information is provided for users and the non-intrusive load identification based subentry measuring smart electricity meter provided by the invention has a good application prospect.

Description

technical field [0001] The invention relates to a sub-item metering smart electric energy meter based on non-intrusive load identification, and belongs to the technical field of electric energy metering. Background technique [0002] Load identification technology is an emerging advanced measurement technology for smart grids. Different from the current smart energy meter that only measures the total power of residential users, it aims to collect fine-grained power consumption behavior data of users, which is an important aspect of smart power consumption. one of the research fields. [0003] Current load identification techniques can be divided into intrusive and non-intrusive load identification methods. Smart sockets are the representative of the former, but they need to be installed at home, and have disadvantages such as difficult promotion and maintenance, low online rate, and high cost. The non-intrusive load identification method only needs to sample the voltage an...
