Abstract

The invention discloses a real-load detection method and system for a non-intrusive load electric energy meter. The method comprises the following steps: S11, connecting a plurality of high-precisionelectric energy meters arranged on real-load branches to a detected non-intrusive load electric energy meter; S12, connecting a standard electric energy meter with the detected non-intrusive load electric energy meter, with the standard electric energy meter being used for obtaining the true value of the total electricity consumption; and S13, comparing the accuracy of the metering data with the accuracy of the load type identification, generating a test result, and judging whether the error, the load type identification and the load switching identification of the detected non-intrusive loadelectric energy meter are qualified or not. The acquired data of the non-intrusive load electric energy meter and the high-precision intelligent electric energy meter are acquired, the acquired electric quantity data of each load branch are compared, and whether the load electric quantity identification of the non-intrusive load electric energy meter is qualified or not is judged.

Description

Technical field [0001] The invention relates to a real-load detection method and system of a non-invasive load electric energy meter, belonging to the technical field of electrical equipment detection. Background technique [0002] With the increase in types and numbers of smart homes, many household appliances have inductive and capacitive non-resistive loads, such as asynchronous motors, rectifier equipment, etc. The huge fluctuations in the electric load current of this kind of dynamic load can cause problems such as frequency deviation, voltage fluctuation, voltage flicker, harmonic distortion, and DC injection, and cause great hidden dangers to the electrical performance and stability of the smart meter. [0003] Household users are an important consumer of a strong smart grid and an important component of the grid. With the increase in types and numbers of smart homes, many household appliances have inductive, capacitive and other non-resistive loads, such as asynchronous mot...
