With the continuous development and improvement of smart power grid, smart electricity meters are widely used as terminal products for measuring electric energy, and the degree of automation of their verification is also getting higher and higher. Therefore, the automatic verification pipeline of smart electricity meters has been rapidly developed. At the same time, in the environment of automatic verification pipeline of intelligent electricity meters, the electromagnetic radiation effect of high-frequency radio signals of mobile communication on the metering accuracy of electricity meters is also gradually attracting attention. In order to study the influence of high-frequency rf signal on the metering of electricity meters, this paper firstly analyzes the interference way of the influence of rf signal on the metering of electricity meters, and analyzes the mechanism of the influence of rf signal on the metering of electricity meters. Second, test the automatic detection line of high frequency radio frequency interference signal strength, environment based on the interference signal modulation mode interference signal mathematical model is established, and then, according to the mathematical model and the measured interference signals of rf signal power spectrum, through the simulation analysis to determine the effect of interference signals of watt-hour meter belongs to a kind of uniformity of the distribution of noise. Finally, the mathematical model of the influence of rf signal on the metering error of electricity meters is established, and the influence of rf signal on the pipeline of intelligent electricity meters is given by analyzing the error of electricity meters through simulation.
