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.
