Abstract

The invention discloses an alternating-current and direct-current integrated power distribution station. The alternating-current and direct-current integrated power distribution station comprises an alternating-current power distribution system and a direct-current power distribution system which are arranged in a power distribution station room. The alternating-current power distribution system supplies power to the direct-current power distribution system through a 0.4 kV feeder switch cabinet; the alternating-current power distribution system comprises two sets of alternating-current power distribution devices which are connected in parallel through a 10kV section switch and a 0.4 kV section switch; and the direct-current power distribution system comprises two sets of direct-current power distribution devices which are connected through a 750V section switch. According to the alternating-current and direct-current integrated power distribution station of the invention, on the basis of satisfying a conventional alternating-current power distribution function, the access requirement of a direct-current power supply and a load can be met.
