Electric energy meter error correction method, device and equipment

Abstract

The invention relates to an electric energy meter error correction method, device and equipment. The method comprises the following steps: extracting corresponding comparison data from a preset errortable, obtaining the temperature value data with the highest fitting degree with the current temperature data of the electric energy meter as the fitting temperature, extracting a metering deviation value corresponding to the fitting temperature from the comparison data, and obtaining a corrected metering result. According to the method, comparison data is obtained from a preset error table; the current temperature data of the electric energy meter is fit with the comparison data, fit temperatures is obtained, and a corresponding metering deviation value is obtained from the comparison data according to the fitting temperature; and finally, the initial meter calibration data is updated according to the metering deviation value, so that the electric energy meter can adopt the updated initial meter calibration data to correct the electric quantity metering at different temperatures, the accuracy of the electric quantity metering of the electric energy meter at different environment temperatures is ensured, and the adaptability of the electric energy meter at different environment temperatures is improved.

technical field [0001] The present application relates to the technical field of distribution network terminals, in particular to a method, device and equipment for error correction of electric energy meters. Background technique [0002] With the development of the economic level, the power consumption level of users has also increased accordingly. When each user uses the electric energy provided by the power grid system, it needs to use an electric energy meter to measure the power consumption of the user, so as to facilitate the power grid. The staff manages the users. [0003] However, the energy meter is easily affected by temperature when measuring electricity, resulting in errors in the measurement data. For example, in some areas with harsh climates and relatively low ambient temperatures or areas with high ambient temperatures, the energy meter is prone to measurement errors.

[0003] However, the energy meter is easily affected by temperature when measuring electricity, resulting in errors in the measurement data. For example, in some areas with harsh climates and relatively low ambient temperatures or areas with high ambient temperatures, the energy meter is prone to measurement errors. Inaccurate measurement occurs

[0004] The traditional electric energy meter comes with corresponding calibration data when it leaves the factory, but the calibration data is obtained according to the reference temperature of the electric energy meter in the normal temperature working environment, and the calibration data cannot be changed with the actual ambient temperature of the electric energy meter. Adjustment, when the energy meter is working in a harsh environment, the meter calibration data cannot accurately calibrate the energy measurement of the energy meter, resulting in the problem of poor applicability of the energy meter
