An Evaluation Method for Electric Energy Meter Operation

Abstract

The invention relates to a method for evaluating the operation of an electric energy meter, comprising the following steps: 1) collecting original data of an on-site electric energy meter through an online monitoring system of a remote metering device, and uploading the original data to a data server of a host PC; 2) the host computer The PC classifies the original data, and establishes a mathematical model for the operation evaluation of the electric energy meter according to the classified original data; 3) According to the established mathematical model for the operation evaluation of the electric energy meter, evaluate the operation of the electric energy meter, and obtain the final result of the electric energy meter. Health index HI, according to the final health index HI to predict the running trend of the electric energy meter and give an early warning. Compared with the prior art, the present invention has the advantages of scientific rationality, many specific research objects, wide coverage, systematization, intelligence and the like.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an evaluation method for the operation of an electric energy meter. Background technique [0002] Gateway metering is an important part of the large marketing system among the three sets of five major systems. The operation of the gateway metering device not only reflects the management level, but also affects the economic benefits of both the electricity seller and the buyer. In order to manage devices fairly, justly, openly, and with credibility, and maintain the seriousness of measurement, it is necessary to refine and classify the operating conditions to provide a scientific basis for technical countermeasures. [0003] This time, the project "Research on the Operation Evaluation System and Remote Status Monitoring Scheme of Gateway Electric Energy Metering Devices" undertaken by the Electric Power Research Institute of Shanghai Electric Power Company in conjunction with Xiamen ...

AI Technical Summary

Problems solved by technology

[0004] At present, electric power companies judge the operating status of electric energy meters operated on site mainly through periodic verification, and periodic verification has problems such as heavy workload, high manpower and material resources, untimely fault discovery, and insufficient basis for power replenishment after faults. series of disadvantages, therefore, it is urgently needed to establish an evaluation method for the operating state of electric energy meters
