摘　　要：针对现场周期性检测能效低、易受干扰的问题,为实现电能计量装置的动态监测和全面评估,本文将依托于现代信息化手段设计一种在线监测与评估系统,首先结合应用需求,给出了系统设计方案,并选定计量电压、电流、相角、功率及异常警告等作为评价指标,运用1-9标度法设定指标权重系统,由此构建基于层次分析法的评价模型,可为电能计量装置运行状态的综合评价提供有效支撑。Aiming at low efficiency and easily interfered problem of periodic detection in the field,this paper designs an on-line monitoring and evaluation system based on modern information means in order to realize the dynamic monitoring and comprehensive evaluation of energy metering device.Firstly,combined with application requirements,the system design scheme is given,and the measurement voltage,current,phase angle,power and abnormal warning are selected as evaluation indexes,the index weight system is set by1-9scale method,thus the evaluation model based on the analytic hierarchy process can be constructed,which can provide effective support for the comprehensive evaluation of the operation state of the electric energy metering device.
