摘 要:以IEC 61850-5標準規定的D2-1配電變電站為實例,利用OPNET軟件建立了統一組網和獨立組網的變電站通信網絡仿真模型,并基于該模型對兩種組網方式的網絡性能和VLAN技術對變電站網絡性能的影響進行了對比分析。仿真結果表明:兩種方案下各交換機負載獨立組網低于統一組網;以太網延時統一組網高于獨立組網;VLAN技術對統一組網網絡性能的影響較獨立組網大。

Abstract: Taking substation D2-1specified by IEC 61850-5 for example, this paper established the unified networking and independent networking dynamic simulation models of substation communication network using software OPNET. Based on the built models, this paper analyzed and compared the impacts from the network performance and virtual local area network (VLAN) technology of the two networking modes on substation network performance. The simulation result shows that each exchanger of load independent networking is lower than that of unified networking, the Ethernet delay of unified networking is higher than that of independent networking and the VLAN technology impacts on unified networking more than on independent networking.
Key words: smart substation; IEC 61850; OPNET simulation; unified networking; independent networking; virtual local area network
