Abstract

The invention discloses an ammeter misalignment detection method and device based on linear regression and electronic equipment; the method comprises the steps: carrying out the generalized partial correlation analysis of the electricity consumption data of all user ammeters in a transformer area, and obtaining the electricity consumption data of the user ammeters meeting a preset condition; and constructing a quadratic programming model which meets the following formula: solving a regression coefficient of the quadratic programming model, and judging the misalignment state of the ammeter of each user according to the solved regression coefficient. The electricity meter misalignment detection method can realize electricity meter misalignment detection when the total number of the electricity meters in the transformer area is larger than the electricity consumption collecting days. Meanwhile, the method can detect the electricity meter misalignment state under the condition that the electricity consumption collecting days are short, and can reduce the possibility of changing the corresponding relation between the electricity meters and the transformer area.

Description

technical field

[0001] The invention relates to the technical field of electric meter detection, in particular to a linear regression-based electric meter misalignment detection method, device and electronic equipment. Background technique

[0002] Due to the comprehensive promotion of the intelligent transformation of electric meters by the State Grid, hundreds of millions of electric meters have been deployed all over the country. The so-called inaccuracy of the electricity meter means that the actual electricity consumption measured by the electricity meter and the electricity measured by the electricity meter are obviously inconsistent. When the actual electricity consumption of the user is greater than the electricity measured by the meter, this is the undercount of the meter, which will damage the operating income of the power supply company; the reason for the undercount of the meter is usually the failure of the meter or the theft of electricity; The actual electric...
