摘要：
The boundary frequency characteristics of continuous co-phase AT(AutoTransformer) traction power supply system and the traction network composed of the capacitor at the exit of the traction substation and a section of catenary line outside the traction network are analyzed. The attenuation effect of traction network and traction network boundary on high-frequency transient signals, and the impact of fault location on high-frequency transient signals detected at protection are analyzed. The study results show that in the current continuous co-phase AT traction power supply system, the attenuation effect of the traction network on the high-frequency transients is smaller than that of the traction network boundary, and the high-frequency transient signals detected by the protection are closely related to the fault location. A simulation model is established to verify the attenuation effects of the traction network of the continuous co-phase AT traction power supply system and the traction network boundary, and the simulative results verify the correctness of the study results. © 2021, Electric Power Automation Equipment Press.
