Embodiment

[0044] Such as figure 1 As shown, an evaluation method for the operation of an electric energy meter includes the following steps:

[0045] 1) Collect the original data of the on-site electric energy meter through the online monitoring system of the remote metering device, and upload the original data to the data server of the upper PC;

[0046] 2) The upper 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, which specifically includes the following steps:

[0047] 21) Obtain the initial health index HI of the energy meter operation 1 , the initial health index HI of the electric energy meter 1 The calculation of is carried out as follows:

[0048] (1) Routine settings

[0049] Set some node values ​​of the health index, including the initial health index of the new device, the theoretical aging health index, the end-of-life health index, the lower limit of...

Abstract

The invention relates to a method for evaluating the operation of an electric energy meter, and the method comprises the following methods: 1) collecting the raw data of an on-site electric energy meter through a remote metering device on-line monitoring system, and uploading the raw data to a data server of an upper PC; 2) classifying the raw data through the upper PC, and building a mathematic model of operation evaluation of the electric energy meter; 3) evaluating the electric energy meter according to the built mathematic model of operation evaluation of the electric energy meter, obtaining the final health index HI of the electric energy meter, predicting the operation tendency of the electric energy meter according to the final health index HI, and carrying out early warning. Compared with the prior art, the method is scientific and reasonable, is large in specific number of research objects, covers a wide range, is systematic, and is intelligent.

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 ...
