| Abstract: | In recent years,the CRH series EMU are launched into high-speed railway lines. The power factor and the current harmonic contents of the CRH series EMU are different from the traditional AC-DC type electric locomotives. This paper briefly analyzes the electrical principle of CRH380AL EMU. On the basis of measured data, the power factor and the current harmonic contents of CRH380AL EMU are analyzed by using curve-fitting method. This basic work is believed to have a certain reference value on analyzing the operation performance of CRH series of EMU and the power quality problem of traction power supply systems. |
