    Abstract:

    In order to evaluate the operation status of electric energy metering devices (EEMD) more comprehensively and accurately, a state evaluation method of the EEMD is proposed on the basis of Fuzzy Analytic Hierarchy Process. The data of each state variable of the EEMD can be obtained by the Internet of Things, and are further used to construct a fuzzy judgment matrix for solving the weight of each layer element. The final score of the target device is calculated by the weighted summation of the weight and the index scores of each layer, and then the interval of the score is used to determine whether each part of the EEMD is normally operating. Through qualitative and quantitative analysis, the proposed method can systematically and effectively reveal the relationship between the final evaluation target and each level. Finally, the effectiveness and accuracy of the method are verified through realistic cases.
