基于IEC61850的变电站通信网络组网研究

Study on Substation Communication Networking Based on IEC 61850

以IEC 61850-5标准规定的D2-1配电变电站为实例,利用OPNET软件建立了统一组网和独立组网的变电站通信网络仿真模型,并基于该模型对两种组网方式的网络性能和VLAN技术对变电站网络性能的影响进行了对比分析。仿真结果表明:两种方案下各交换机负载独立组网低于统一组网;以太网延时统一组网高于独立组网;VLAN技术对统一组网网络性能的影响较独立组网大。

Taking substation D2-1specified by IEC61850-5 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.
