Embodiment

[0078] Such as figure 1 As shown, a method for determining a substation network VLAN configuration problem includes the following steps:

[0079] Step 1, compare the VLAN configuration of the design document with the VLAN configuration of the switch; if the VLAN configuration of the design document is the same as that of the actual device, go to step 2;

[0080] Step 2, compare the VLAN division of the SCD with the VLAN division of the switch; if the VLAN division of the SCD is the same as that of the switch, go to step 3; if the VLAN division of the SCD is different from the VLAN division of the switch, go to step 5;

[0081] Step 3, monitor the data flow of the VLAN port of the SCD and the data flow of the VLAN port of the switch in real time; if the data flow of the VLAN port of the SCD is inconsistent with the data flow of the VLAN port of the switch, perform step 4;

[0082] Step 4, if the difference between the data traffic of the VLAN port of the SCD and the data traff...

Abstract

The invention discloses a method for determining the VLAN configuration problem of a substation network, which comprises the following steps: step 1, comparing the VLAN configuration of a design document with the VLAN configuration of an actual device; step 2, determining the VLAN configuration problem of the VLAN configuration of the actual device; step 3, determining the VLAN configuration problem of the VLAN configuration document. If the VLAN configuration of the design document is different from that of the actual device, the VLAN configuration of the actual device is incorrect; If the VLAN configuration of the design document is the same as the VLAN configuration of the actual device, go to Step 2; 2, comparing the VLAN configuration of the SCD with the VLAN configuration of the switch; if the VLAN configuration of the SCD is the same as the VLAN configuration of the switch, go to Step 3; if the SCD VLAN configuration is not the same as the switch VLAN configuration, go to Step 5. The invention also discloses a system for determining a VLAN configuration problem of a substation network. The invention judges which one of the SCD configuration error, the optical fiber blockingand the switch configuration error is the specific network communication problem, so as to achieve the purpose of comprehensively and accurately judging the network communication problem of the intelligent substation.

Description

technical field [0001] The invention relates to the field of network VLAN configuration, in particular to a method and system for determining the problem of substation network VLAN configuration. Background technique [0002] The traditional problem of judging the network communication of smart substation is generally to establish a communication fault monitoring server to network with cascaded switches and devices through the entrance switch. status, so as to judge the fault of smart substation network communication according to the status of network communication. However, this method cannot comprehensively and accurately judge the communication problem for the situation caused by single or comprehensive effects such as the configuration of the SCD, the configuration of the switch, and the status of the real-time communication port. Contents of the invention [0003] In order to solve the above technical problems, the present invention aims to provide a method and syste...
