Abstract

The invention relates to a transformer loss analysis and control method based on remote calibration of an operation error of a grid line. The method based on a novel electric energy metering theory isa mathematical method; and an actual error of an electric energy metering device is measured by detecting an electric energy data error. Therefore, a technical problem of poor practicability of the metering function of the power automatic equipment is solved. Calculation and analysis are carried out by using bid electric energy data; transformer loss calculation is completed rapidly while the power is not interrupted; and thus the transformer loss analysis and control method based on remote calibration of an operation error of a grid line is realized.

Description

technical field [0001] The invention belongs to the field of electric energy measurement, in particular to a transformer loss analysis and control method based on remote calibration of grid line operation errors. Background technique [0002] At present, the general "energy meter + transformer" structure determines that there is an unmeasurable "dead knot" in the energy metering device: the error of the energy meter is a scalar, and the error of the current and voltage transformer is a vector of the ratio difference and the angular difference. Operations cannot be performed between vectors and scalars. The error of the electric energy metering device cannot be obtained by separately detecting the error of the electric energy meter and the transformer. Moreover, the number of household electric energy meters is huge, the inspection workload is too large, and the detection must be powered off, which constitutes a major problem that the error of the electric energy metering de...
