Intelligent substation station control layer network topology structure

The invention discloses an intelligent substation station control layer network topology structure, which comprises a first switch, a second switch, a third switch, a fourth switch and a central switch, wherein the first switch, the second switch, the third switch and the fourth switch are mutually connected to form a ring network; the central switch is respectively connected with the first switch, the second switch, the third switch and the fourth switch; and the first switch, the second switch, the third switch and the fourth switch are respectively connected with an intelligent substation bay level device to form a cobweb structure. The intelligent substation station control layer network topology structure has the beneficial effects that advantages of a star network and the ring network are both provided; the network structure is distinct; and on the premise of not increasing network facilities, the network redundancy is high, the reliability is high, the expansibility is good, a network storm does not ex
