Embodiment Construction

[0042] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 as shown, figure 1 It is a structural diagram of the substation process layer message common network and common port transmission system in this embodiment; the system includes a process layer network that connects the interval layer and the process layer through edge preprocessing equipment; the process layer network includes a network based on all-optical switching technology all-optical switch.

[0044] The process layer network realizes the transmission of GOOSE messages and SMV messages on the same network and port through the edge preprocessing equipment process layer, edge preprocessing equipment and all-optical switches.

[0045] All-optical switching means that optical signals are directly switched from input terminals to different output terminals without any optical-electrical conversion in the ...

Abstract

Provided is a transformer substation process layer message network-sharing port-sharing transmission system. The system comprises a process layer network, wherein the process layer network is connected to a spacing layer and a process layer via an edge pre-processing device, and the process layer network comprises a switch based on an all-optical switching technology. The system adopts the all-optical switching technology to achieve the network-sharing port-sharing transmission for GOOSE and SMV messages of the process layer of a transformer substation via the edge pre-processing device, thereby avoiding multiple times of optical-electric conversion on each node of a communication network.

Description

technical field [0001] The invention relates to a method in the technical field of communication network in an intelligent substation, and specifically relates to a transmission system for substation process layer messages sharing a network and a common interface. Background technique [0002] At present, the network switching equipment in the substation is based on the Ethernet core switching chip that processes electrical signals, and adopts the "store-and-forward" network switching mode. Send it to the Ethernet core switch chip, the switch chip first caches the incoming data packets from the input port and checks them. After confirming that the packets are correct, take out the destination address, find the address of the output port you want to send through the lookup table, and then send the packet go out. Optical-to-electrical conversion in multiple links will cause a large conversion delay and affect the real-time performance of services. At the same time, the elect...
