Intelligent electric energy meter operation and maintenance replacement method and device based on on-line comprehensive evaluation

Abstract

The invention relates to an intelligent electric energy meter operation and maintenance replacement method and device based on on-line comprehensive evaluation, wherein the method comprises the stepsof: obtaining at least one evaluation index affecting the operation state of the intelligent electric energy meter; obtaining index data of the intelligent electric energy meter corresponding to the at least one evaluation index respectively; calculating an evaluation score of the intelligent electric energy meter corresponding to the at least one evaluation index respectively based on the index data of the at least one evaluation index; synthesizing at least one evaluation score to obtain an evaluation total value of the intelligent electric energy meter; determining whether to rotate the smart electric energy meter according to the total evaluation value. By evaluating the running state of intelligent watt-hour meter, whether the intelligent watt-hour meter needs to be rotated is determined, so that the intelligent watt-hour meter can be rotated only for the intelligent watt-hour meter which needs to be replaced, so that the rational and accurate replacement of the intelligent watt-hour meter is realized, the waste of resources can be reduced, the positive operation of the intelligent watt-hour meter can be ensured, the workload of the intelligent watt-hour meter installation, disassembly, replacement and fault treatment can be reduced, and the operation and maintenance cost of the power system can be reduced.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to an operation and maintenance management method of an intelligent electric energy meter, especially an operation and maintenance replacement method and device for an intelligent electric energy meter based on online comprehensive evaluation. Background technique [0002] Smart grid is an informatized, digitized, automated, and interactive power transmission network. Smart energy meter is a basic information collection unit in smart grid and plays a very important role in the process of grid intelligence. With the prolongation of use time, problems such as mechanical wear and aging of electronic components will occur in smart electric energy meters, which often lead to inaccurate measurement of intelligent electric energy meters. In order to ensure the measurement accuracy of smart energy meters, maintenance management such as inspection and regular rotation o...

Problems solved by technology

[0003] However, the existing smart energy meters all use a unified manual fixed cycle for on-site inspection and rotation. The degree of aging is not the same, which is likely to cause a large part of the smart energy meters in normal operation to be removed for testing, or a large part of the overloaded smart energy meters cannot be rotated in time, resulting in low rotation accuracy. Not only will it consume a lot of manpower and material resources, but it will also cause power outages for users, and there may be friction with users and the possibility of on-site operation safety accidents. The method of manually repairing and rotating electric energy meters can no longer meet the lean operation and maintenance requirements of modern smart grids. need
