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.

This paper describes the commissioning methodologies and roadmap for an IEC 61850-90-5 based synchrophasor system, including PMUs, PDCs, IRIG-B and IEEE 1588 GPS clocks, synchrophasor streaming protocols and historian storage. It especially addresses lessons during the commissioning of this large-scale synchrophasor system deployment.
