摘　　要：以IEC 61850中的D2-2型变电站为例,针对几种典型的继电保护通信系统结构,通过不交化最小路集法,计算并分析系统的可靠性,筛选出同时兼顾可靠性和经济型的二次系统配置方案,并运用Optimized Netw ork Engineer tools(OPNET)仿真软件,结合继电保护相关信息流的特点,应用IEEE 802.1Q优先级标签和划分本地虚拟局域网(Virtual Local Area Network,VLAN)技术对D2-2型变电站进行仿真,得出了不同继电保护通信系统结构下影响保护实时性的主要因素,并针对智能变电站的保护控制系统配置提出了建议.With IEC61850 D2-2 type of substation,by adopting disjoint minimal path sets algorithm,the system＇ s reliability is calculated and analyzed, and the configuration schemes of protective network is given which takes into considetation the reliability and economy. Under this configuration, by using Optimized Network Engineer Tools （OPNET） simulator, the protective data in D2-2 type substation is simulated based on IEEE 802.1Q priority-tag and VLAN technology. The main factors affecting the delay of protective data are discussed under different system configura- tion. Suggestions of intelligent substation protection and control system are proposed.
