Abstract

The invention discloses a three-meter-method three-phase electric energy meter structure for user error self-checking and a checking method. A mathematical model is established by using an electric energy conservation relation of an electric energy meter structure, and electric energy data detected by a split-phase total meter metering module, a split-phase auxiliary meter module and a split-phase meter calibration circuit metering module of a three-way structure are calculated. Calculating electric energy measurement errors of a split-phase total meter metering module, a split-phase auxiliary meter module and a split-phase meter calibration circuit metering module of the three-way array structure, and compensating electric energy data obtained by new measurement through errors obtained by calculation; measuring errors of the split-phase total meter metering module, the split-phase auxiliary meter module and the split-phase meter calibration circuit metering module are continuously and iteratively calculated, a phase combination error is calculated, and error-free or equal-error data of the three-meter-method three-phase electric energy meter with the user self-calibration error is obtained. 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 a three-meter method three-phase electric energy meter structure and a verification method for user self-verification errors. 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...
