分析了郑西高铁越区供电时保护方案存在的问题。高铁全并联AT越区供电时,如果被越区段发生阻抗一段和变电所的电流速断出口故障,将导致被越区段停电,影响越区供电的正常进行。本文给出了改进方案。
It analysis the existing problem of protection schemes at the all parallel AT traction with cross-area power supply mode of the ZhengXi-high speed railway. When using the Cross-area power supply, if the cross-area section goes wrong, the power supply of section occurs would interruption, which would disturb the normal operation.
