Embodiment

[0066] Such as figure 1 As shown, the process layer network includes multiple switches at the process layer, measurement and control devices and protection devices at the process layer, intelligent terminals and merging units at the bay layer. Each switch is connected to at least one interval device and one process layer device, which is used for transparent transmission of GOOSE / SV information transmission between the interval layer and process layer devices to replace the direct connection of physical terminals in traditional substations.

[0067] Such as image 3 As shown, the measurement and control device CXL2201 subscribes to the PRIT / gocb0 of the intelligent terminal IXL2201, the measurement and control device CXL2201 is connected to the switch SW2201, and transmits signals to the intelligent terminal IXL2201 through the switch SW2201. The specific implementation steps are as follows:

Abstract

The invention discloses an intelligent substation process layer switch configuration information analysis method, including the following steps that: 1) a background host first parses an SCD file of an intelligent substation, and extracts valid information under an IED node in the SCD file and under a communication node in the SCD file of the intelligent substation, stores the valid information ina database, and distinguishes the information stored in each table by using different table names; 2) the background host executes a pre-designed database script file, and finally generates a GOOSE / SV release control block signal flow table; and 3) the background host extracts and converts the information in the control block signal flow table, and exports a switch VLAN, a multicast forwarding table and port default VLAN information as configuration files. By adopting the scheme of the invention, intelligent substation process layer switch configuration files can be rapidly and accurately generated and delivered to a switch to complete automatic configuration, and thus the efficiency of forwarding table configuration of a switching device at an intelligent substation site can be greatly improved, and an effective means of reducing artificial configuration errors can be achieved.

Description

technical field [0001] The invention relates to a method for analyzing configuration information of a process layer switch in an intelligent substation, and belongs to the technical field of electric power automation. Background technique [0002] In the smart substation, the communication network with the switch as the core plays a key role. The traditional hard-wiring method is canceled between the interval layer and the process layer, and information such as switch signals and sampling values ​​are transmitted through the switch network. The information is GOOSE / SV message format transmission. On-site manual configuration of switch VLAN, multicast table, etc. to ensure the correct forwarding of GOOSE / SV packets, the workload is heavy and error-prone, and the error correction process after errors are also very cumbersome. Therefore, it is of great significance to realize the automatic configuration of switches in engineering applications. Contents of the invention [...
