Substations Based System Protection System Based on Intelligence Center

The present invention discloses a substation protection system based on intelligent center system. Substation systems with a wireless local area network, wide area network, and three kinds of optical fiber communication networking, using their respective advantages achieved within each substation, efficient communication between substation and substation protection and smart center; the same time, protection intelligent center system using an optical fiber communications to achieve its acquisition and processing module real-time acquisition of operating data substation substation system, via its communication module, fault location determination module and a trip decision module for analysis and calculation of the collected data, ultimately in station domain to protect the substation exit inspection by the intelligent protection system as a central backup protection system failure substation to replace the substation failure protection function, which greatly improves the reliability of the system hub substation.
