| 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. |

| Keywords: | smart meter Weibull distribution maximum likelihood estimation failure early warning |
