The invention discloses a combined type electrified railway flexible automatic neutral section passing device and a control method thereof. The combined type electrified railway flexible automatic neutral section passing device comprises a direct current bus DB, an alternating current bus BL, an alternating current bus BR, a measurement and control instrument MC, at least one alternating current-direct current converter AD1, at least one alternating current-direct current converter AD2, at least one alternating current-direct current converter AD3 and at least one alternating current-direct current converter AD4, dC ports of the AC-DC converters AD1, AD2, AD3 and AD4 are all connected to the DC bus DB, AC ports of the AC-DC converters AD1, AD2, AD3 and AD4 are respectively connected to the AC bus BL, the uplink neutral section N1, the downlink neutral section N2 and the AC bus BR, and the power supplies on the left side and the right side and the n AC-DC converters share a DC bus topological structure. Every two alternating-current and direct-current converters can be conveniently combined into the alternating-current, direct-current and alternating-current converters to achieve neutral section locomotive power supply, control and switching, expansion is convenient, the left power supply side and the right power supply side share the alternating-current, direct-current and alternating-current combination mode of neutral section power supply, the maximum combination function is achieved through the least alternating-current and direct-current converters, and the device cost can be reduced.
本发明公开了一种组合式电气化铁路柔性自动过分相装置及其控制方法,包括直流母线DB、交流母线BL、交流母线BR、测控器MC、至少一个交直变流器AD1、至少一个交直变流器AD2、至少一个交直变流器AD3和至少一个交直变流器AD4,所述交直变流器AD1、AD2、AD3、AD4的直流端口均连接于所述直流母线DB上,其中,交直变流器AD1、AD2、AD3、AD4的交流端口分别连接于交流母线BL、上行中性段N1、下行中性段N2、交流母线BR,该左右两侧电源与n个交直变流器共直流母线拓扑结构,便于交直变流器两两组合成交直交变流器实现中性段机车供电、控制与切换,便于扩展,左右电源侧共用‑中性段分别供电的交直交组合形式,采用最少的交直变流器实现最大组合功能,能够降低装置成本。
