Topology real-time verification method for process level switch of intelligent substation

Abstract

The invention discloses a topology real-time verification method for a process level switch of an intelligent substation, and relates to the technical field of intelligent switches in the power industry. The method comprises the steps of obtaining subnet information, equipment information and switch port connection information by analyzing an SCD file; obtaining process layer switch equipment information from the equipment information, and obtaining a process layer switch port expected connection table according to the process layer switch equipment information and the connection information of each port of the switch; establishing MMS communication for all process level switch devices in a switch communication subnet, and acquiring public information logic node information and neighbor information logic node information of each port of all process level switch devices under the same subnet in real time; according to the neighbor information logic node information of each port, obtaining real-time actual connection relation information of the process layer switch equipment; and according to the real-time actual connection relation information of the process layer switch equipment, judging whether sub-network division and switch interfaces are wrong, thereby completing process layer switch topology real-time verification.

Description

technical field [0001] The invention belongs to the technical field of intelligent switches in the electric power industry, and in particular relates to a real-time topology verification method for process layer switches in intelligent substations. Background technique [0002] As the basic communication facilities of smart substations, Ethernet switches play an important role in supporting the safe, stable and reliable operation of smart substations. In recent years, with the advancement of smart substation construction, traditional power industry Ethernet switches have gradually highlighted certain limitations in the application process of smart substations. The configuration of optical fiber connection is complicated, and it is difficult to check after the configuration is completed. On-site staff often have errors in subnet division and port connection during the connection process. [0003] The network communication and physical optical fiber connection ports of the sm...
