摘要： 随着智能电网的建设，智能电能表投运数量出现大幅增长。基于现场可靠性数据，使用极大似然法对智能电能表的分布参数进行估计，提出了智能电能表批次故障预警和寿命预估方法。实际验证结果表明，所提方法可以预警存在故障的智能电能表批次，预估可靠寿命，为智能电能表轮换机制的优化提供理论和数据支撑。

关键词: 智能电能表, 威布尔分布, 极大似然法, 故障预警

Abstract: With the construction of smart grid, the number of smart meters has increased significantly. Based on the field reliability data, the maximum likelihood method is used to estimate the distribution parameters of batch smart meters, and a batch fault early warning and life prediction method of batch smart meters is proposed. Verification results show that the proposed method can warn the batch of faulty smart meters, predict the reliable life, and provide theoretical and data support for the optimization of smart meter rotation mechanism.

Key words: smart meter, Weibull distribution, maximum likelihood estimation, failure early warning
