System and method for automatic partition of intelligent substation and optimization of VLAN

Abstract

A system for automatic partition of an intelligent substation and optimization of a virtual local area network comprises a data importing module, a generating module, a checking module and a performance evaluation module, wherein the data importing module, the generating module, the checking module and the performance evaluation module are sequentially connected in the importing data flow direction, the generating module directly transmits data to the performance evaluation module and the checking module, the performance evaluation module further feeds the data back to the generating module, and the performance evaluation module outputs the data finally. The invention further relates to a method for automatic partition of the intelligent substation and optimization of the VLAN. The system and the method have the uniform partition principle, are reasonable and distinct in partition, can conduct conversion check, will not produce human errors, and reduce workload of manual configuration of the VLAN of the intelligent substation.

Description

technical field [0001] The invention relates to a system for automatically dividing and optimizing VLAN (Virtual Local Area Network) in an intelligent substation. The invention also relates to a method for using the system to automatically divide and optimize VLANs in intelligent substations. Background technique [0002] At present, smart substations are based on networked communication, and its biggest feature and advantage is information sharing. In the substation, more and more message data will be transmitted in the communication network, and the system puts forward higher requirements for the real-time and reliability of message transmission. Devices are logically divided, and devices with the same working nature are concentrated in the same VLAN, limiting the transmission of information within each VLAN, reducing the data flow across VLANs to reduce the workload of switches, improving network transmission efficiency and communication quality, and meeting the real-tim...

AI Technical Summary

Problems solved by technology

[0004] 1. It is difficult to divide the substation VLAN, there is no unified division principle, mainly based on the work experience of the management personnel, and the number of equipment in the substation is large, resulting in fuzzy VLAN division;

[0005] 2. There is no anti-verification in the existing VLAN division of smart substations. Generally, it is only required that the equipment can receive the messages that should be received, and it does not perform corresponding processing on the received messages that should not be received;

[0006] 3. The configuration of VLAN division is mainly set manually one by one, which is prone to human errors, resulting in unreasonable VLAN division.
