摘要: 在分析智能变电站过程层网络主要数据SMV、GOOSE、PTP1588报文共网传输的可行性基础上,指出过程层组网最佳方案是星形拓扑;对比VLAN与GMRP 2种报文过滤技术,以IEC 61850标准中的D2-1典型变电站为例,提出了一套基于间隔的VLAN局域网逻辑结构划分方案,对其中存在的各种数据流流量、通信时延及时延抖动进行了详细说明和计算,最后利用OPNET仿真软件对共网传输时数据流时延进行仿真,论证了采用VLAN技术共网传输的可行性。

Abstract: On the basis of a feasibility study of the common network transmission of the main data SMV, GOOSE and PTP1588 message of intelligent substation process level network, the star topology is considered to be the optimal scheme for process layer network. Through comparison of two packet filtering technologies, VLAN and GMRP and by taking the typical substation D2-1 in IEC 61850 as an example, a set of interval-based VLAN logic structure classification schemes were proposed, and a detail description and computation was made of common the existing data flow, communication delay and delay shaking. Finally, the data flow delay of the common network transmission was simulated with software OPNET, which demonstrated the feasibility of the common network transmission by VLAN technology..

Key words: intelligent substation, common network transmission, VLAN, data flow analysis
