Method for calculating misalignment rate of electric meter

Abstract

The invention discloses a method for calculating the misalignment rate of an electric meter. The method comprises the following steps: S1, acquiring related data in a transformer area on line througha metering monitoring instrument; S2, according to the condition of the related data, determining a reference value, that is, the electric quantity of the transformer area, as the reference value, andcalculating the misalignment rate of each electric meter by utilizing the law of conservation of energy; S3, after the misalignment rate of each electric meter is obtained through calculation, conducting secondary screening on the misalignment electric meters according to misalignment reasons, and independently marking the electric meters which cannot be solely solved through meter replacement. According to the invention, online monitoring of all intelligent electric meter data is more accurate, the misalignment rate of each electric meter in the transformer area is obtained based on calculation of the data model, electric meter state evaluation is carried out according to the misalignment rate, and accurate meter replacement is completed.

Description

technical field [0001] The invention belongs to the field of information technology and relates to a calculation method for the misalignment rate of electric meters. Background technique [0002] With the further popularization of smart meters, grid data has been further enriched and expanded in terms of quantity and timeliness, especially the online monitoring data of equipment has been further enriched, providing data support for online monitoring of metering asset status. The full life cycle of metering equipment covers all stages from procurement and delivery management, equipment acceptance management, verification and testing management, warehousing and distribution management, equipment installation management, equipment operation management, equipment dismantling management to final asset scrap management. Among them, the power grid mainly includes the following processes in the operation and management process of smart meters: the first mandatory verification, the f...

Problems solved by technology

However, the actual operating life of electric energy meters can generally reach 10 to 15 years, and the quality level of electric energy meters on the grid can be effectively monitored, so the "one size fits all" expiration rotation mechanism is unreasonable, and the number of electric energy meters that pass the verification and are scrapped in advance is huge. It is not conducive to energy saving and environmental protection, and wastes social resources. At the same time, changing the meter will cause the old dismantling, new purchase and installation, etc., resulting in a huge waste of manpower and material resources.
