中文摘要:

智能电能表作为电能计量装置的核心设备,其运行状态直接影响着电能计量的准确性和公平性,因此对电能表运行状态进行准确评价至关重要。针对现有的电能表状态评价方式存在的问题,提出了一种新型电能表运行状态评价方法。以电能表现场试验、基本信息和运行监测指标为基础建立了运行状态评价体系；针对评价体系指标众多,各项指标重要性横向比较困难、缺乏客观性的问题,建立了基于模糊层次分析法(FAHP)的运行状态评价模型；考虑到异常状态值的淹没问题,提出了通过权重自适应调整对运行状态评价模型的改进,动态反映各个指标对电能表的影响。算例分析证明了FAHP可得到合理的评价权重系数,权重自适应调整算法避免了单个子指标异常越限的淹没,评价结果更加准确、合理。
