Embodiment 1

[0029] see image 3 , a smart substation process layer multicast management method, comprising the following steps:

[0030] Step S1, using static multicast technology, performing static multicast configuration on the switch according to predetermined rules, and generating a static multicast configuration table;

[0031] Step S2, forwarding the multicast of the MAC address registered in the static multicast configuration table according to the configured port.

[0032] The static multicast technology realizes the forwarding of the multicast frame of a specific MAC address to the configured port by manually configuring the static multicast configuration table of the switch, and the multicast frame of the MAC address will not appear on other ports.

[0033] As a better example, such as Figure 4 As shown, the process of performing static multicast configuration according to predetermined rules and generating a static multicast configuration table can be specifically as follows...

Embodiment 2

[0055] Corresponding to the above-mentioned smart substation process layer multicast management method, the present invention also provides a smart substation process layer multicast management device, such as Figure 7 As shown, the device includes:

[0056] The static multicast configuration module (1) is used for adopting static multicast technology, performing static multicast configuration on switches according to predetermined rules, and generating a static multicast configuration table;

[0057] A forwarding module (2), configured to forward the multicast of the MAC address registered in the static multicast configuration table according to the configured port.

[0058] preferred, such as Figure 8 As shown, the static multicast configuration module may include:

[0059] A first initialization unit (10), configured to determine the quantity and mutual relationship of MUs and IEDs;

[0060] A second initialization unit (12) connected to the first initialization unit i...

Abstract

The invention provides a multicast management method and a device for an intelligent substation process level. The multicast management method includes the steps of according to a scheduled rule, performing static multicast configuration by utilizing a static multicast technology to generate a static multicast configuration table; and forwarding multicast of a media access control (MAC) address registered in the static multicast configuration table according to a configuration port. According to the multicast management method and the device for the intelligent substation process level, the multicast technology is adopted, the static multicast configuration table is generated in advance, the forwarding of the registered multicast at a designated port is achieved according to the static multicast configuration table, which multicast addresses are received by each intelligent electronic device (IED), namely, which merging unit (MU) are associated with the IED is quite intuitive, when the designated port receives other multicast massages, problems can be determined to exist in network settings or other network aspects, and therefore on-site maintenance of engineering debugging staff is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a process layer multicast management method of an intelligent substation and a process layer multicast management device of an intelligent substation. Background technique [0002] Intelligent substations and digital substations are based on the same standard IEC 61850 and the same communication platform Ethernet. According to the IEC61850 standard, the substation communication system is divided into three layers, namely the station control layer, the interval layer and the process layer. Among them, the process layer network refers to the network between the interval layer and the process layer, which mainly transmits GOOSE (Generic Object Oriented Substation Event, Generic Object Oriented Substation Event), SV (Sample Value, sampling value) and IEEE1588 clock synchronization data. We know that data packets on the Ethernet can be divided into unicast (Unicast) packets, multi...
