The invention discloses a motor train unit neutral section passing traction assistance and train supply no-interconnection power supply implementation method. The method comprises the steps that S1, a neutral section passing prediction signal is detected; the forecast signal is sent to a traction system, an auxiliary system and a train supply system, and the motor train unit begins to pass through the neutral section; s2, four quadrants are pulled to start neutral section passing control preparation, so that a first actual power grid phase is synchronized to a simulated power grid phase of a phase section; s3, synchronizing the simulated power grid phase to a second actual power grid phase; and S4, the main section is closed, the traction four-quadrant, the auxiliary four-quadrant and the train supply four-quadrant enter a normal working mode, and the neutral section passing power supply process is ended. According to the invention, interconnection lines among the traction four-quadrant, the auxiliary four-quadrant and the train supply four-quadrant are cancelled, so that the cost is reduced, and the difficulty of production, manufacturing and maintenance is reduced; Meanwhile, in the neutral section passing implementation process, virtual power grid signals are transmitted between the traction supply auxiliary system and the train supply system, so that the reliability of neutral section passing power supply of the motor train unit is improved.

    本发明公开了一种动车组过分相牵引辅助及列供间无互连线供电实施方法,包括:S1:检测到过分相预告信号;并将预告信号发送到牵引系统、辅助系统和列供系统,动车组开始过分相;S2:牵引四象限开始进行过分相的控制准备,以将第一实际电网相位同步到分相区的模拟电网相位;S3:将模拟电网相位同步到第二实际电网相位;S4:主段闭合,牵引四象限、辅助四象限和列供四象限进入到正常工作模式,过分相供电过程结束。本发明取消牵引四象限、辅助四象限和列供四象限之间的互连线,降低成本,同时降低生产、制造、维护的难度;同时在过分相实施过程中,牵引给辅助系统及列供系统之间传递虚拟电网信号提高了动车组过分相供电的可靠性。
