The invention discloses a distributed power supply access control system. The system comprises a hardware layer, an operating system layer, a support platform layer and an application layer. The hardware layer is used for supporting hardware equipment of the distributed power supply access control system. The hardware equipment includes IBM servers, HP servers and PC machines. The operating system layer is used for supporting an operating system of the distributed power supply access control system. The support platform layer is used for processing integrating servers, data servers and public service servers. The application layer which comprises an EMS system, a DMS system and a marketing system is used for integrating real-time systems of the EMS system, integrating real-time systems of the DMS system and further integrating real-time systems of the marketing system. The distributed power supply access control system which can conveniently and rapidly achieve distributed power supply access control further achieves distributed power supply distribution information integration and eliminates information isolated islands. The distributed power supply access control system achieves distributed power supply application intelligentization integration and sharing.
