Key Object Modeling and Performance Simulation of Process Level Networks in Smart Substation

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 220 kV 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.
