Method for evaluating operation of secondary loop of metering device

Abstract

The invention relates to a method for evaluating the operation of a secondary loop of a metering device, and the method comprises the following steps: 1) collecting original data of the secondary loop of an on-site metering device through a remote metering device on-lie monitoring system, and uploading the original data to a data server of an upper PC; 2) classifying the original data through the upper PC, and building a mathematic mode for the operation evaluation of the secondary loop of the metering device according to the classified original data; 3) evaluating the operation of the secondary loop of the metering device according to the built mathematic mode for the operation evaluation of the secondary loop of the metering device, obtaining the final health index HI of the secondary loop of the metering device, predicting the operation tendency of the secondary loop of the metering device 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 a secondary circuit of a 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] 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 conjunct...

AI Technical Summary

Problems solved by technology

[0004] At present, the electric power company mainly judges the operation status of the secondary circuit of the metering device in the field through periodic verification, but the periodic verification has a large workload, consumes a lot of manpower and material resources, the fault is not found in time, and the basis for power recovery after the fault is not sufficient. Therefore, it is urgently needed to establish an evaluation method for the operation status of the secondary circuit of the metering device.
