Abstract

The invention discloses a sub-item metering smart electric energy meter based on non-intrusive load identification, which includes a non-intrusive load identification module integrated inside the intelligent electric energy meter, and the non-intrusive load identification module can be printed on the intelligent electric energy meter or the non-intrusive load identification module is connected to the circuit main board of the smart energy meter through a connector, and the non-intrusive load identification module is installed in the smart energy meter box or installed in the smart energy meter module In the warehouse: the non-intrusive load identification module is used to identify various types of loads installed indoors, and separate the sub-item measurement results of each load type, and output the corresponding sub-item measurement results. The invention integrates the non-intrusive load identification with the existing intelligent electric energy meter, improves the existing intelligent electric energy metering level, provides users with more abundant electricity consumption information, and 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...
