高海拔典型环境下电能表误差与环境影响因素研究
Study on Error of Meter with Environmental Factors under High Altitude Typical Environment
In this paper, we use meter basic error test data, what were extracted from the monitoring platform in Tibet typical environments built by the State Grid, to analyze the relationship between the error of meter and environmental factors under high-altitude environment. First of all, with using environmental data, the establishment of XGBoost model has accurately identified and predicted the out of tolerance of meter error. Then, by establishing multiple linear regression model, the quantitative analysis of the environmental factors on the meter error has been done. Finally, it is concluded that temperature is the most important environmental factor that affects out of tolerance and the value of meter error, and the influence of humidity and rays of the sun is more important. Wind speed, air pressure, rain&snow have little effect on the error of meter.
