Abstract:
A Process Control (PC) or Substation Automation (SA) system is disclosed with appropriate message filtering based on Virtual Local Area Network identifiers VLAN-IDs as communication sub-network identifiers. The VLAN-IDs are determined in order to optimize data flow in the sense that receiver IEDs only receive the intended messages, while at the same time the number of sub-network identifiers can be reduced to a maximum extent. Restricting the real time traffic in such a way can ensure proper operation of the systems, such as large SA systems using GOOSE for interlocking and having sensors connected with the Sampled Value (SV) protocol according to IEC 61850-9-2.
