Impact Analysis and Testing of Harmonic of Electrified Railway on Energy Metering

This paper analyzed the characteristics of electrified railway power supply combine of the status quo on electrified railway power supply and energy metering. According to the metering principle of the electrical energy meter, this essay theoretically analyzed the impact of harmonic of electrified railway on energy metering. By comparing the analytical laboratory and field test data, the adverse influence of harmonics generated by electrified railway power supply on energy metering is studied and come to a conclusion that the electrified railway user is less metered the power while the linear user is more metered.
