On-line monitoring area inaccurate rate calculation method, equipment and medium

Abstract

The invention discloses an on-line monitoring area inaccurate rate calculation method, equipment and a medium. The method comprises steps as follows: S1, acquiring time-point electric quantity data ofeach user meter under a master meter in an area online; S2, verifying whether acquired electric quantity data of the master meter in the area are 0, determining that the master meter is not used or the master meter fails if the electric quantity data of the master meter in the area are 0, and performing further calculation if the electric quantity data of the master meter in the area are not 0; S3, calculating error rates of each user meter, line loss rate of the area and fixed loss of the area according to a prototype flow conservation formula of a data application electric energy meter error rate model acquired online; and S4, calculating the error rate of the master meter by use of a correction model, and correcting the error rates of each user meter, the line loss rate of the area andthe fixed loss of the area. With the implementation of the method, for online monitoring calculation of the inaccurate rate of an intelligent electric meter, considering factors for calculation of the inaccurate rate are richer, output of result amount is increased, and the result is more reliable and accurate.

Description

technical field [0001] The invention belongs to the field of information technology, and relates to a calculation method, equipment and media for the misalignment rate of an online monitoring station area. 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:...

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.
