Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0022] The embodiment of the invention discloses a substation networking system. The networking system of the substation is based on the smart substation with three layers and two networks. Specifically, the networking system of the substation includes: a process layer, a process layer network, a bay layer, a station control layer network and a station control layer. Each of the process layer, the interval layer and the station control layer is provid...

The embodiment of the present invention discloses a substation networking system, including: a process layer, a process layer network, an interval layer, a station control layer network, and a station control layer; each wireless access device of the process layer network is connected to at least Electronic equipment on one process floor, or connected to at least one electronic device on the interval floor; each wireless access device on the station control floor network is connected to at least one electronic device on the station control floor, or connected to at least one interval floor between the wireless access devices of the process layer network, between the wireless access devices of the station control layer network, between the wireless access device of the process layer network and the wireless management device of the process layer network, and the station control layer network The wireless access device and the wireless management device of the station control layer network are connected wirelessly, so that both the process layer network and the station control layer network form a star-assisted grid-type wireless networking topology, which solves the problem of broadband bottlenecks and Defects such as forwarding delay.
Description
technical field [0001] The invention relates to the technical field of substations, in particular to a networking system of a substation. Background technique [0002] At present, smart substations generally use wired media and switches to connect smart substation secondary equipment (protection, measurement and control, smart terminals, merging units, etc.) and smart substation monitoring systems. The commonly used network topologies are bus, star and ring. The devices in the bus network share the same wired transmission medium. When two nodes in the network send data at the same time, conflicts will occur; the star network consists of a central node located in the center of the network and slave nodes connected to it. The communication between nodes must be forwarded by the central node to proceed smoothly. When there are many devices, a problem with the central node will cause the entire network to be paralyzed; the ring network consists of multiple switches connected to...
