Abstract Existing flexible phase-separation passing technologies for electrified railways face problems including large capacity requirements for converters and arcing caused by the separation with current between pantograph and contact wire. Thus, this paper proposed a more practical flexible uninterrupted phase-separation passing system and its control strategy. The proposed system connects the power phases on both sides of the phase-separation through a back-to-back converter. The single-phase inverter is drawn from the DC link of the back-to-back converter and connected with a phase-shifting transformer in series to maintain the voltage on the neutral wire. The connected phase-shifting transformer can effectively reduce the capacity of converters. With the goal of passing the phase-separation without power interruption, overvoltage and arcing, the working principle of the proposed system is analyzed in detail, and a control strategy with flexible voltage transition and power adjustment ability is proposed. Next, the effectiveness of the proposed system and control strategy is verified by the Matlab/Simulink-based simulation and the RT-Lab-based hardware in the loop experiment. Finally, the required capacity of the converters in the proposed system is analyzed, according to the practical operation scenarios of electric railways. Based on the analyzed results, some application suggestions of the proposed system are advised.

Key words： Electrified railway phase-separation uninterrupted phase-separation passing power adjustment phase-shifting transformer
