Embodiment Construction

[0037] 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 only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] The present invention provides a VLAN-based method for suppressing broadcast storms in the process layer network of smart substations. figure 1 Shown is a schematic diagram of the central switch and multiple bays in the smart substation. The multiple bays are one bus bay, two transformer bays and six feeder bays. The bus bay is equipped with a bus bay switch, and each transformer bay is equipped with a A transformer bay switch, each feeder bay is provid...

Abstract

The invention discloses a VLAN-based method for suppressing broadcast storms in the process layer network of intelligent substations. The method is used to suppress broadcast storms in the process layer network of intelligent substations. Bay and six feeder bays, bus bay with a bus bay switch, each transformer bay with a transformer bay switch, each feeder bay with a feeder bay switch, transformer bay switch, each transformer bay switch and each feeder The bay switches are all connected to the central switch. The present invention gives different VLAN IDs to each port of the switch through VLAN technology and sets whether to support each VLAN ID. Wherein, if the VLAN ID of one port A supports the VLAN ID of another port B, then port A can forward the VLAN ID from port B. If the message is not supported, it cannot be forwarded to limit the transmission range of the message, thereby reducing the impact of the broadcast storm on the real-time communication.

Description

technical field [0001] The invention relates to the technical field of message sending / receiving in an intelligent substation, in particular to a VLAN-based method for suppressing broadcast storms in a process layer network of an intelligent substation. Background technique [0002] The communication system of the smart substation includes substation level equipment, bay level equipment and process level equipment. IEC61850 divides the smart substation into process level, bay level and station control level. The communication network can be divided into: the station control layer network between the station control layer and the bay layer, and the process layer network between the bay layer and the process layer. The process layer network is mainly used to transmit GOOSE (Generic Object Oriented Substation Event, object-oriented substation event) messages and SV (Sampled Value, sampled value) messages between bay layer devices and process layer devices. At present, the proc...
