The Error Model of the Smart Meter Under the Influence of Low Temperature

摘要

This paper focuses on the impact of low temperature environment on the measurement performance of smart meter. Based on the actual test data of the smart meter in the low temperature environment and processing software such as Matlab and Origin, we can investigate the relationship and influence level among the low temperature environment, operating load and metering performance of the smart meter. The data from the test field of smart meter in the actual operating condition of low temperature is set up in Mohe county of Heilongjiang province. The test functions of the meter include short and long-distance detection system, load control system, protection system and environmental monitoring system. And the research results show that the low temperature environment induces a shift to negative direction of the smart meter error, so that we can obtain the mathematical model of the smart meter with the change of temperature at different loads.
