The invention discloses a grid-side converter system of a rail train and a control method thereof. The grid-side converter system comprises a voltage transformation module, a non-electrical power supply module, a rectification module, a support capacitor and a controller. the controller is used for detecting whether a pantograph is connected with a power supply line or not after the pantograph ascends, if so, detecting a power supply mode of the power grid voltage on the power supply line, and controlling the voltage transformation module and the rectification module to operate in a working mode corresponding to the power supply mode so as to enable the rectification module to charge the support capacitor and keep the voltage of the support capacitor at a preset target voltage for the inverter to use, and if not, controlling the non-electrical power supply module to output the electric energy to the rectification module to enable the rectification module to charge the support capacitorafter receiving the electric energy, and maintaining the voltage of the support capacitor at a preset target voltage. Visibly, the requirements of multiple power supply systems can be met, and the rail train can run in a non-electrified railway section, so that the fusion of various types of rail transit lines can be promoted.
本发明公开了一种轨道列车的网侧变流系统及其控制方法,网侧变流系统包括变压模块、非电气供电模块、整流模块、支撑电容及控制器;控制器用于在受电弓升弓后,检测受电弓上是否连接有供电线,若是,则检测供电线上电网电压的供电制式,并控制变压模块和整流模块在供电制式对应的工作模式下运行,以使整流模块为支撑电容充电,并将支撑电容电压保持在供逆变器使用的预设目标电压;若否,则控制非电气供电模块输出电能至整流模块,以使整流模块在接收到电能后为支撑电容充电,并将支撑电容电压保持在预设目标电压。可见,本申请可满足多供电制式的要求,且轨道列车可实现在非电气化铁路区段运行,从而有助于推动各类型轨道交通线路的融合。
