摘　　要：为满足智能变电站过程层网络及自动化应用系统的性能分析需求,提出了基于OPNET(optimizednetwork engineering tools)的变电站过程层网络建模与仿真方法。基于变电站自动化系统应用需求,分析了实体设备、IEC 61850标准、调度策略和组网结构的建模要求,研究了变电站过程层网络关键对象的建模方法。结合220 kV典型变电站,构建了完整的变电站过程层网络性能分析模型,分析了正常运行和故障运行状态下的网络性能,为开展智能变电站过程层网络及其自动化系统的性能分析提供了研究工具。For meeting the demand of performance assessment of process level networks and automation application system of smart substations, a substation process level network modeling and simulation method was provided based on OPNET（Optimized Network Engineering Tools）. This paper analyzed the modeling requirements of physical units, IEC 61850, scheduling strategies and networking architecture; and studied the key object modeling method of process level networks of substation. Based on a typical 220kV substation, the performance assessment model of substation process level networks was established and the network performance was analyzed under normal and fault operations respectively. This paper provides an effective research tool for the performance assessment of process level networks and automation system of smart substations.
