The invention provides a railway vehicle, a railway vehicle ventilation system and a control method thereof.The railway vehicle ventilation system comprises a main power supply circuit and a standby storage battery power supply circuit, the main power supply circuit is provided with a ventilator frequency converter, and the standby storage battery power supply circuit is provided with an emergency ventilation inverter; comprising the following steps: judging whether a ventilator frequency converter fails and is locked; if the ventilator frequency converter is not subjected to fault locking, the main power supply circuit is opened or kept and controlled to supply power to the ventilator through the ventilator frequency converter; and if the ventilator frequency converter fails and is locked, the standby storage battery power supply circuit is opened and controlled to boost and invert the storage battery power supply through the emergency ventilation inverter and then supply power to the ventilator. According to the system, when the ventilation function fails due to reasons, the ventilation system autonomously enters the emergency ventilation inverter operation mode, the alternating current power supply is provided for the ventilator, the ventilator is started to operate, and the reliability of the air conditioning unit and the comfort of passengers are effectively improved.

    本发明提供了轨道车辆、轨道车辆通风系统及其控制方法,轨道车辆通风系统包括主供电线路和备用蓄电池供电线路,主供电线路具有通风机变频器,备用蓄电池供电线路具有紧急通风逆变器,包括以下步骤:判断通风机变频器是否故障锁定;若通风机变频器未故障锁定,则开启或保持主供电线路并控制主供电线路通过通风机变频器向通风机供电;若通风机变频器故障锁定,则开启备用蓄电池供电线路并控制备用蓄电池供电线路通过紧急通风逆变器将蓄电池电源升压逆变后向通风机供电。在本发明中,通风系统实现在通风功能因故失效时,自主进入紧急通风逆变器运行模式,为通风机提供交流电源,通风机得以启动运行,有效的提高了空调机组的可靠性和乘客舒适性。
