The invention discloses a combined type pressure wave control system and method for a power concentration motor train unit. The combined type pressure wave control system comprises pressure protection before and after entering a tunnel, pressure protection after entering the tunnel and pressure protection before and after leaving the tunnel. The pressure protection before and after entering the tunnel adopts a pressure wave valve closing mode for pressure protection; the pressure protection after entering the tunnel adopts the combination of passive pressure protection and forced pressure wave valve control protection; the pressure protection before and after the tunnel exit adopts a pressure wave valve closing mode for pressure protection. According to the system, in-vehicle pressure protection and air quality can be greatly guaranteed when the vehicle runs in and out of the tunnel, in and out of the continuous tunnel group, in and out of the short tunnel and in the tunnel, the comfort of passengers is improved, and a technical basis is provided for running of the power-concentrated motor train unit in a more complex line environment.
本发明公开了一种动力集中动车组用复合式压力波控制系统及方法,包括进隧道前后的压力保护,进隧道后的压力保护和出隧道前后的压力保护;所述进隧道前后的压力保护采用压力波阀关闭的方式进行压力保护;所述进隧道后的压力保护采用被动式压力保护和强制压力波阀控制保护相结合;出隧道前后的压力保护采用压力波阀关闭的方式进行压力保护。本发明可以大大保证车辆进出隧道、进出连续隧道群、进出短隧道、隧道内运行时的车内压力保护及空气质量,提高乘客舒适性,为动力集中动车组在更复杂线路环境运行提供了技术基础。
