A system and method for statistical processing of operating error data of a smart electric energy meter

Abstract

The invention proposes a system and method for statistical processing of operating error data of a smart electric energy meter. Based on the error statistics requirements, an error statistics terminal closely related to other parts of the system is designed, and a sample table is provided by connecting the feedback receiving terminal and the monitoring terminal for system decision-making. Based on the statistical results of error statistics, an online monitoring and data acquisition system and method based on the distributed acquisition system, station configuration information and the same type of reference information are designed. Affects light load error, sampling circuit sampling error and attribution error. By normalizing the ternary verification information, it realizes error statistics that are convenient for UI display and system management, and based on multi-dimensional underlying monitoring parameters Realize convenient system monitoring.

Description

technical field [0001] The invention belongs to the new-generation intelligent Internet of Things information technology field, and in particular relates to a system and method for statistical processing of running error data of an intelligent electric energy meter. Background technique [0002] Error is the measured quantity minus the reference quantity. The measured value is referred to as the measured value, which represents the value of the measurement result. The error that the electric energy measuring instrument has under the specified working conditions. The allowable basic error limit is referred to as the basic error limit for short. Working conditions refer to the verification working conditions stipulated in the national verification regulations. The basic error of the electric energy meter stipulates the relative percentage error, which is determined as follows: relative error = ((measured result (indication) - measured true value) / measured true value) * 10...
