The invention discloses a ground electrified automatic neutral section passing system and a control method thereof, and relates to the technical field of electrified railway traction power supply, the system is provided with a first neutral section and a second neutral section, and a neutral section passing execution unit comprises a first phase-change switch, a second phase-change switch, a third circuit breaker and a fourth circuit breaker; a first phase-change switch and a second phase-change switch are connected with a first power supply arm and a second power supply arm on the two sides of a traction network respectively, and dynamic adjustment of the length of a neutral section is achieved by controlling the opening and closing states of a third circuit breaker and a fourth circuit breaker through a control unit. The position detection unit is used for detecting the position information of the train, and a basis is provided for the control unit to open and close the neutral section passing execution unit. The length of the neutral area is changed according to the working state of the ground electrified automatic neutral section passing system, the requirements that a train passes through the long neutral section in an electrified mode in the normal state and passes through the short neutral section in a power-off coasting mode in the fault state can be met at the same time, and the traffic capacity of a line is improved.

    本发明公开了一种地面带电自动过分相系统及其控制方法,涉及电气化铁路牵引供电的技术领域,系统设置第一中性段和第二中性段,过分相执行单元包括第一换相开关、第二换相开关、第三断路器和第四断路器;通过第一换相开关、第二换相开关分别与牵引网两侧的第一供电臂和第二供电臂连接,通过控制单元对第三断路器和第四断路器的开闭状态控制实现中性段长度的动态调整;利用位置检测单元检测列车的位置信息,为控制单元对过分相执行单元的分合操作提供依据。本发明依据地面带电自动过分相系统的工作状态变换中性区的长度,能够同时满足正常状态下列车带电通过长中性段以及故障状态下列车断电惰行通过短中性段的需求,提高了线路的通行能力。
