Performance Of Iec 61850 Different Communication Channels Protection Networks For Smart Grids
IEC 61850 is starting to be used in substation automation systems and now it has become a communication standard for the smart grid. This paper provides an evaluation on the real-time capability of the communication network in inter- substation communication in three scenarios using Ethernet and WLAN analyzing for over-current protection. Communication is modelled according to the standard IEC 61850 stack using both simulation for WLAN and the analytical approach of Network Calculus for Ethernet. Thus, we determine the delay of SV and GOOSE messages, evaluating the impact of varying packet length and sampling frequency on network and traffic conditions. For performance evaluation we developed a simulation model along with an analytical approach on basis of Network Calculus, enabling to identify worst case boundaries for inter-substation communication.
