    摘要:

    为了更全面准确地对电能计量装置运行状态进行评估,提出了一种基于模糊层次分析法的电能计量装置状态评估方法。通过物联网传输电能计量装置的各状态量数据,构造模糊判断矩阵并进一步求解各层元素的权重,再由权重和各层次指标评分通过加权求和计算出评估目标的最终得分,由得分所在的区间段来判断电能计量装置各个部分是否正常运行,通过定性与定量综合分析,能够系统有效地分析最终评估目标和各层次之间的关系,最终通过实例分析验证了该方法的有效性和准确性。

    Abstract:

    In order to evaluate the operation status of electric energy metering devices more comprehensively and accurately, a state evaluation method of the electric energy metering device based on Fuzzy Analytic Hierarchy Process is proposed. The data of each state quantity of the electric energy metering device transmitted by the Internet of Things are used to construct a fuzzy judgment matrix and further solve the weight of each layer element, and then calculate the final score of the evaluation target through the weighted summation of the weight and the index score of each level. The final score of the evaluation target is calculated by weighted summation from the weight and the index scores of each level, and then the interval of the score is used to determine whether each part of the electric energy metering device is operating normally. Through qualitative and quantitative comprehensive analysis, it can systematically and effectively analyze the relationship between the final evaluation target and each level. Finally, the effectiveness and accuracy of the method are verified through case analysis.
