| 摘要: |
| 目前虚拟局域网（VLAN）的配置主要由人工完成，工作量大，且缺乏统一的标准和评价指标，容易出现人为错误，给保护控制系统的可靠性带来隐患。分析了VLAN优化配置的约束条件，并基于智能变电站通信网络拓扑结构和设备间报文订阅关系等建立了VLAN配置的通信网络模型。结合VLAN模型，提出了报文最短路径的计算算法，进而实现了VLAN的自动配置与优化。以某实际智能变电站的VLAN优化配置为例，将所提优化方法与现有优化方法进行对比分析，结果证明了所提方案的有效性和实用性。 |

| Abstract: |
| Without unified standards and evaluation index，the manual configuration of VLAN（Virtual Local Area Network） may easily have mistakes，bringing potential hazards to the reliability of protection and control system. The constraints of VLAN configuration optimization are analyzed and its communication network model is established according to the topological structure of smart substation communication network and the packet subscription relationship among equipments，based on which，a method to calculate the shortest packet path is proposed for the automatic configuration and optimization of VLAN. With an actual substation as example，comparison between the proposed method and the existing method is carried out to show its effectiveness and practicability. |
