Abstract The low-frequency oscillation in the traction network is a new phenomenon as with AC-DC-AC locomotives utilized in electric railways. However there are few researches focused on it. It has been noted that the low-frequency oscillation in Xuzhou North Railway Hub is particularly extraordinary because it caused abnormal voltage fluctuation. Therefore, it is necessary to investigate this low-frequency oscillation phenomena in detail. By designing test plan, we do some measurements in Xuzhou North Traction Substation and Sub-feeder Switching Post (SFSP). Besides, the voltage and current of primary winding of traction transformer in HXD2B locomotive are also measured to fully analyze whether low-frequency oscillation is caused by traction network or locomotive. And then through the analysis on data and waveform, the cause of low-frequency oscillation of electric railway is concluded. Finally, some measures to suppress low-frequency oscillation are put forward.
