IED modelling for IEC61850 based substation automation system performance simulation

This paper introduces the modeling of intelligent electronic device (IED) on OPNET modeler, a communication network modeling and simulation tool developed by OPNET TECHNOLOGIES. These configurable IED models allow to easily build substation automation system (SAS) network model with different topologies for all kinds of substations so that the dynamic performance issues could be studied during the planning stage and network performance problem could be caught ahead of the deployment stage. An example of using those models to construct SAS network on OPNET Modeller as well as the network performance simulation results is also included in this paper
