SCD file based VLAN automatic configuration method and device, and switch

Abstract

The invention discloses an SCD (Substation Configuration Description) file based VLAN (Virtual Local Area Network) automatic configuration method and device, and a switch. The SCD file based VLAN automatic configuration method comprises the steps of inquiring an FDB (Forwarding Database) table to obtain a corresponding relationship between a port number and an MAC (Media Access Control) address; analyzing a GOOSE message or SV message received by a port, obtaining the MAC address and iedName of an IED (Intelligent Electronic Device) which sends the GOOSE message or SV message, and building a corresponding relationship between the port number and the iedName; analyzing the SCD file to obtain a corresponding relationship between the iedName of a publisher with a publishing-subscribing relationship and the iedName of a subscriber; and dividing the port number with the publishing-subscribing relationship into the same VLAN. According to the SCD file based VLAN automatic configuration method and device provided by the embodiment, other data list information is unnecessary to guide into the switch as information is obtained based on the message received by the port and the information is combined with the SCD file information, automatic configuration is realized really, manual workload is reduced, the complexity of the existing VLAN distribution method is reduced, and good compatibility with other technologies of an intelligent switch is obtained.

Description

technical field [0001] The invention relates to the technical field of VLAN configuration of switches, in particular to an SCD file-based VLAN automatic configuration method, device and switch. Background technique [0002] The IEC61850 standard is the only universal standard in the field of power system automation in the world. IEC61850 divides the substation into a "three-layer and two-network" structure, where the "two networks" represent the station control layer network and the process layer network respectively. The process layer network includes substation secondary protection devices, measurement devices, control and signal devices, etc. SCD (abbreviation for substation configuration description, that is, the system configuration file of the whole station) describes the communication relationship and the publish-subscribe relationship of the secondary devices of the whole station. The GOOSE message issued by each publishing device has a VLANID identifier. Automatic...

Problems solved by technology

[0003] However, the currently commonly used VLAN (Virtual Local Area Network abbreviation, virtual local area network) configuration is based on manual configuration, the workload is huge, and errors are prone to occur, which is contrary to the development trend of smart substations.

However, the current SCD-based automatic VLAN configuration technology cannot obtain all the information and data automatically allocated from the SCD. It needs to manually import other record data tables to assist in the completion of VLAN configuration, and there is no real realization of fully automated VLAN configuration.
