Research on the state evaluation of electric energy meter based on double entropy correction index weighting
A comprehensive and accurate evaluation of the state of the electric energy meter will help guide the actual maintenance work and reduce the waste of resources. In this paper, based on the double entropy correction index weighting, a state evaluation method of electric energy meter is proposed. Specifically: First, according to the principle of index establishment, a relatively complete evaluation index system of electric energy meter status is sorted out and constructed. Secondly, the traditional entropy method has been improved, and a method to determine the index weighting based on the double entropy is given, which takes both the subjective experience and objective regularity of the evaluation index into account. Then, a state evaluation model of electric energy meters is proposed and applied in a provincial power grid, and the state characteristics of electric energy meters of different categories and batches are preliminarily analyzed. Compared with traditional evaluation methods, the effectiveness and superiority of the proposed method are highlighted. Finally, combined with the field experience and the state evaluation results of the electric energy meter, a flexible periodic inspection strategy of the electric energy meter is given, which can reduce the consumption of material and manpower.
