Abstract

The invention discloses an electric energy meter structure and an error checking method for a user himself / herself. Establishing a mathematical model by using an electric energy conservation relationship of an electric energy system, and calculating an electric energy measurement error of the user electric energy metering module according to electric energy data detected by the user electric energy metering module, the auxiliary meter module and the error reference standard device of the three-way array structure; and compensating the newly measured electric energy data through the calculated error, continuously iteratively calculating the measurement error of the user electric energy metering module and the auxiliary meter module, and obtaining the user electric energy metering module without error or with equal error. According to the method provided by the invention, the multi-collinearity influence of electric energy data calculation caused by similar electric energy using habits of users can be weakened, and the calculation efficiency and the calculation precision are improved.

Description

technical field [0001] The invention belongs to the technical field of smart meter measurement, and more specifically relates to an electric energy meter structure and a method for verifying errors by users themselves. Background technique [0002] At present, a large number of flow sensors, such as electricity meters, water meters, gas meters or other flow meters, cannot be dismantled back to the laboratory to detect flow errors because they are used too much in real life. There is an urgent need to find technologies and methods for online detection of these flow sensor errors; [0003] For mathematical algorithms, when the flow measurement system is relatively large, there are many flow sensors included in the flow measurement system, and the similarity of user flow consumption habits will lead to multicollinearity problems in flow meter data. Calculation accuracy is affected. [0004] The traditional method is to install a flow sensor on the pipeline or node of the meas...
