摘　　要：文章将传统模糊层次分析法进行改进并应用于配电网电能表运行质量评价。模型将电能表运行质量采用准确率指标、故障率指标、可靠率指标,事件记录可靠性四类宏观指标进行评估并分别制定方案层指标。在数据的预处理工作之后通过专家打分法形成两两之间的成对比较矩阵,并基于反馈过程对主观性较强的评分权重进行调节;针对成对比较矩阵计算其最大特征值以及相应的最大特征向量,将该向量进行归一化处理得到各指标的评价权重,并基于最大特征值构建相关并进行一致性检验。最后采用所建立的模型对某地区配电网内电能表运行质量进行改进模糊层次评估,针对实际电能表的评估结果表明所建立的模型能够有效评价电能表的运行状态。In this paper,the traditional fuzzy analytic hierarchy process is improved and applied to the operation quality evaluation of electricity meters in distribution network.The operation quality of electricity meter is evaluated by four macro indices including accuracy rate index,failure rate index,reliability rate index and event record reliability,and the scheme level indices are formulated respectively.After data preprocessing,a pairwise comparison matrix is formed by expert scoring method,and the subjective scoring weight is adjusted based on the feedback process.For the pairwise comparison matrix,the maximum eigenvalue and the corresponding maximum eigenvector are calculated,the vector is normalized to obtain the evaluation weight of each index,and the correlation is constructed based on the maximum eigenvalue and the consistency is tested.The model established in this paper is used to improve the operation quality of electricity meters in a regional distribution network.The evaluation results of actual electricity meters show that the established model can effectively evaluate the operation status of electricity meters.
