The invention provides a new energy power generation unit accessed traction power supply system, and relates to the field of electrified railway traction power supply. The two ports of a new energy power generation unit are respectively connected with the power supply arms at the two sides of a traction power supply system substation and are connected in parallel with power supply arm loads. A measurement and control unit is connected with the measuring ends of a voltage transformer and a current transformer and the control end of the new energy power generation system, and the new energy power generation unit and the traction substation jointly output power to a traction load. With the purpose that the new energy power generation unit outputs power to the railway load to the maximum degree, the power generation capacity of the new energy power generation unit is set as a reference value, when the load power is smaller than or equal to the reference value, the new energy power generation unit outputs power as needed, and when the traction load power is larger than the reference value, the new energy power generation unit and the traction substation output power to the traction load at the same time, so that the new energy power generation control, utilization and consumption are achieved, and the power quality problems of traction load peak clipping, negative sequence restraining and the like can be solved.
