The invention provides a new energy power generation system applied to an electrified railway, and belongs to the technical field of electrified railway traction power supply. A power generation unit is electrically connected with a collection bus, and a traction alternating current unit a and a traction alternating current unit b are connected to the collection bus in parallel; the alternating-current output end of the traction alternating-current unit a and the alternating-current output end of the traction alternating-current unit b are connected with an overhead line system; the power generation unit, the traction alternating current unit a and the traction alternating current unit b are all in communication connection with the control unit; and the control unit is used for realizing energy management of the whole system. The new energy power generation unit, the traction converter unit a and the traction converter unit b all comprise independent converters, two-way controllable transmission of energy can be achieved, and electric energy management is more flexible; the traction converter unit a and the traction converter unit b only need one transformer to be connected to a traction network, namely, one traction converter unit can be directly connected to the traction network for operation through a multi-level converter.

    本发明提供一种应用于电气化铁路的新能源发电系统,属于电气化铁路牵引供电技术领域,发电单元电性连接汇集母线,牵引交流单元a和牵引交流单元b并列连接在汇集母线上,牵引交流单元a的交流输出端和牵引交流单元b的交流输出端均连接接触网;发电单元、牵引交流单元a、牵引交流单元b均通信连接所述控制单元;所述控制单元用于控制单元用于实现整个系统的能量管理。本发明新能源发电单元和牵引变流单元a、牵引变流单元b均包含独立变流器,可实现能量的双向可控传输,电能管理更加灵活;牵引变流单元a、牵引变流单元b仅需一台变压器接入牵引网,即其中一个牵引变流单元可由多电平变流器实现直接接入牵引网运行。
