Abstract

The invention relates to a metering device fault judgment method based on four-quadrant electric energy data, and the method comprises the steps of obtaining the electric energy data collected by a metering automation terminal, filtering the electric energy data, and obtaining tide reverse data; determining corresponding identification information according to the tide reverse data, and calling historical data in a preset time period from a database through the identification information, wherein the historical data comprises four-quadrant electric energy data; determining the active electricquantity and the reactive electric quantity of the four-quadrant electric energy data at each continuous moment, performing comparative analysis on the active electric quantity and the reactive electric quantity, and judging whether a metering device corresponding to the identification information has a fault or not according to an analysis result; according to the invention, the four-quadrant electric energy data is used for analyzing the tide reverse data, manual operation is not needed in the process, the judgment time is short, the labor cost and the time cost are greatly reduced, and meanwhile the working efficiency is effectively improved.

Description

[0001] This application claims the priority of the Chinese patent application with the filing date of June 28, 2020 and the application number of 202010597337.0. technical field [0002] The invention relates to the technical field of electric energy metering data analysis, in particular to a method and system for determining faults of a metering device based on four-quadrant electric energy data. Background technique [0003] With the development of smart grids, electric power companies use metering automation systems and remote communication technology to obtain data from multi-function electronic energy meters for power settlement, data analysis and line loss statistics, replacing the original manual meter reading. , On-site inspection, relying on the data of the loss of pressure and cut-off timer to judge the working mode of the fault. [0004] In the current metering automation system, the system master station can screen abnormal data by itself, such as current interru...
