The invention relates to the technical field of rail transit electrification, and discloses an alternating current and direct current cooperative compensation power supply system. The incoming power supply is coupled with a rectification compensation transformer and a single-phase transformer; the single-phase transformer is connected with the alternating-current bus through the rectification compensation device to form an alternating-current output line; the rectification compensation transformer is communicated with the direct-current bus and the grounding steel rail to form a direct-current output line; and alternating-current and direct-current cooperative compensation power supply is realized through the alternating-current output line and the direct-current output line. The problems that a vehicle base power supply system is low in system electric energy utilization efficiency, large in occupied area and high in cost, and the electric energy quality of an incoming line power source is poor can be solved.
