Abstract

The real-time transaction processing was a key and challenging technology to protect systems from various failures in smart substation. This paper introduces the time critical communication between the protection and control devices and the primary apparatuses in threelevel communication network architecture based on IEC61850, and analyses the process of information exchange and delay requirement of Protection and Control (P&C) applications between level and level, bay and bay, station and station in smart substation. The generic model of the P&C applications was modelling by latency requirement on OPNET, then the simulation and discussion on using those models to construct IEC61850 network validated the real-time of the application model. In the meantime, the delay performance of the P&C application is analysed in scenarios multiple services sharing substation network, which is an attempt to discuss the possibility of establishing a smart substation network simulation platform on OPNET.
