Non-intrusive sub-metering collection system

Abstract

The invention discloses a non-intrusive sub-metering collection system, wherein an intelligent electric energy meter transmits local sub-metering information to an II type concentrator through an RS485 communication bus; the II type concentrator communicates with a main station device through a 4G network; the local sub-metering information includes time scales, total electric quantity of time intervals, total number of electrical appliances and detailed operation information of each electrical appliance; the detailed operation information of each electrical appliance includes types of indoorelectrical appliances, and electricity consumption of time intervals, operation situation of time intervals, and start-stop time information which are respectively metered by category through the indoor electrical appliances; the intelligent electric energy meter is internally provided with a load identification function module, which identifies categories of the local indoor electrical appliancesthrough a built-in algorithm unit, respectively meters the categories to form local sub-metering information and output the result, transmits the result to the intelligent electric energy meter and uploads the same to the II type concentrator. The invention can maximize the transmission of sub-metering information by using the existing power consumption information collection system.

Description

technical field [0001] The invention relates to a non-invasive sub-item metering collection system and method, belonging to the technical field of intelligent electric energy measurement. Background technique [0002] At present, smart energy meters can be combined with load identification technology to identify and measure the electricity consumption of indoor appliances, thereby enabling power supply companies to provide users with more intelligent electricity services. [0003] Load identification technology is an emerging smart grid advanced measurement technology, which is divided into two types: intrusive and non-intrusive. The load identification technology is integrated with the smart energy meter, and electrical appliances are identified at the main incoming line, which is the non-intrusive load. identification technology. [0004] Non-intrusive load identification electrical equipment has the advantages of convenient installation and maintenance, no user sense, an...

AI Technical Summary

Problems solved by technology

[0004] Non-intrusive load identification electrical equipment has the advantages of convenient installation and maintenance, no user feeling, and large-scale promotion. However, because this technology is in its infancy, there is no precedent for large-scale collection based on it. The existing load identification technology and The load identification technology integrated in the collection terminal adopts the manual on-site collection scheme, or builds a separate communication channel by itself, which has no promotion value
