Abstract
Harmonic characteristics of catenary current and traction characteristics play so important role in the traction systems of electric multiple unit (EMU). Throughout the track and measurement of a new type EMU, this paper is aimed to analyze the harmonic characteristics of catenary current by Fourier transform method and figure out the curve of traction characteristics by electric power method. Test results indicate that the catenary current of the new type EMU are in low harmonic, whether the EMU is at the state of traction or braking. When the input power of EMU is above 5 MW, harmonic content of the catenary current is below 1% and total harmonic distortion rate is less than 3%. At the same time, equivalent disturbance current is below 1.5 A and power factor is above 0.98. In addition, the new type EMU has the similar traction characteristics as other EMUs.
