Embodiment Construction

[0025] Such as figure 1 As shown, the MAC address matching based intelligent substation network equipment topology dynamic identification method proposed by the present invention firstly constructs 4 modules, configuration module, network equipment topology identification module, visualization module and event trigger module, and realizes its functions on each module , the implementation steps are as follows:

[0026] Step 1: Complete the necessary configuration for the dynamic identification of smart substation network topology through the configuration module. The functions of the configuration module include: 1) Import the SCD configuration file of the smart substation to be identified, and simplify it through program processing, only including substation communication configuration, IED 2) Select the message listening port (that is, the network interface card); 3) SNMP parameter configuration, including SNMP version (such as version1, version2c) and port (161), etc.; 4) Au...

Abstract

The invention discloses a dynamic recognition method for intelligent substation network device topology based on MAC address matching. The method includes the steps that an corresponding relation table between the IP address / multicasting address of an intelligent electronic device (IED) and the name of the IED is obtained through analyzing an intelligent substation configuration file (SCD), and a corresponding relation table between the IP address / multicasting address of the IED and an MAC address is obtained through analyzing a section data message; an MAC address forwarding table of a switch is obtained through a simple network management protocol (SNMP); the MAC address serving as a foreign key is matched with the two-dimensional table to generate a switch port-IED name table, so that topology recognition of the switch and the connected IED is finished, and graphic displaying is performed. Based on a common topology search method of the switch, the method achieves dynamic recognition of IED topology in a network and helps the operation management level of the intelligent substation network to be improved.

Description

technical field [0001] The invention relates to a method for dynamically identifying topology of network equipment in an intelligent substation based on MAC address matching, and belongs to the technical field of electric power automation. Background technique [0002] The intelligent substation based on IEC61850 adopts Ethernet as the communication network of the substation, and its automation system is logically divided into a three-layer architecture of station control layer, bay layer and process layer. Equipment (IED), the process layer equipment includes intelligent terminals, merging units and other IEDs that interface with primary equipment. The network communication between the station control layer and the bay layer of the smart substation follows the manufacturing message specification (MMS), and the switch signal is transmitted between the bay layer and the bay layer, between the bay layer and the process layer equipment using the general object-oriented substati...
