Remote Evaluation Method for Measurement Error of Large-Scale Smart Meters Considering Environmental Factors

There are some problems such as high maintenance cost, poor accuracy in smart meters on-site verification. This paper presents a remote evaluation method for the measurement error of large-scale smart meters considering environmental factors. The measurement error model of smart meter considering temperature and humidity factor is established. By calculating the fluctuation percentage of measurement error, the operation error of smart meter in the station area is inferred. Based on the analysis of actual examples, the results show that the method can effectively evaluate the measurement error of smart meters in large-scale stations and improve the accuracy and speed of judgment.
