Abstract

The invention relates to an original meter reading data processing method for remote calibration of operating errors of an intelligent electric energy meter. The original meter reading data processingmethod comprises the processing steps that 1, real-time checking is performed; 2, data integrity is checked; 3, data integration is adding of electric energy meter reading data to historical meter reading data of the electric energy meter based on original meter reading data; 4, missing items are processed; 5, data analysis is performed to find out abnormal data; 6, orthogonal checking is performed. The original meter reading data processing method utilizes a flow conservation principle and a big data analysis technology to achieve remote detection of massive online operating electric energymeter errors without standard device adding, meter structure change and electric energy meter cluster topology change. By adopting the method, a correction topology model based on virtual branch circuits is established, wire loss is a variable value, calculation results and change are concerned, 100% reliability of electric energy meter error measurement is achieved, and the electric energy meteris more accurately guided to change work.

Description

technical field

[0001] The invention belongs to the field of electric energy measurement, in particular to a method for processing original meter reading data used for remote calibration of operating errors of intelligent electric energy meters. Background technique

[0002] The accuracy of electric energy metering devices in operation has always been a hot issue that residents and State Grid Corporation are most concerned about. At present, the State Grid Corporation uses statistical analysis methods or adding online detection equipment to realize the supervision and evaluation of the operating errors of smart energy meters. Although the statistical analysis method has changed the single-phase electric energy meter used by residents in the past from regular rotation to random inspection, it is still the control of the overall batch; adding online monitoring equipment will definitely increase the purchase and maintenance costs of the enterprise. This method maintains Costly...
