In response to the external power supply connection requirements of power distribution stations in areas with weak local power grids,elaborate on the technical scheme of 220(110)kV power supply for shared traction substation.Based on the analysis of the availability of 27.5 kV power supply on the traction secondary side,a detailed comparison is made between the system principles and advantages/disadvantages of the 27.5 kV single-phase power supply inverter scheme using cascaded AC-DC-AC conversion technology and the traction 27.5/10 kV series compensation power supply purification scheme,Propose utilization plans for traction power systems that can adapt to different application scenarios.
