Method for evaluating operation state of gateway electrical energy metering device

Abstract

The invention relates to a method for evaluating the operation state of a gateway electrical energy metering device, and the method is characterized in that the method comprises the following steps: 1) collecting the raw data of an on-site gateway electrical energy metering device 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 gateway electrical energy metering device according to the classified raw data; 3) carrying out the grade evaluation of the operation state of the gateway electrical energy metering device according to the built mathematic model of operation evaluation of the gateway electrical energy metering device, building an operation evaluation system for the gateway electrical energy metering device, predicting the operation tendency of the gateway electrical energy metering device according to the operation evaluation system for the gateway electrical energy metering device, 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 systematized, and is intelligent.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method for evaluating the operating state of a gateway electric energy metering device. 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] At present, the operating status of electric energy metering devices operating on site is mainly judged through periodic verification. However, there are a series of disadvantages in periodic verification, such as heavy workload, high manpo...

AI Technical Summary

Problems solved by technology

[0005] At present, domestic and foreign electric power research institutions and enterprises have not formed an evaluation system for the operation status of power metering devices at gateways, and most of them focus on single-direction or decentralized research, most of which are monitoring systems, which are fundamentally limited to status research
