Co-Simulation for the Evaluation of IEC 61850 based Protection Schemes

The paper describes a dedicated co-simulation architecture to combine power system (PS) simulation and information and communications technology (ICT) simulation, to assess new protection schemes fully compliant with the IEC 61850 standard. The interaction between the two simulators has been validated by an example showing the generated Ethernet traffic by a simple substation protection scheme under a power system fault condition. Simulation results are presented from the power system perspective, by means of voltage and current oscillography and from the ICT system perspective, using an especially developed sequence diagram of the transferred Ethernet messages. By using the proposed architecture, the time performance of protection schemes based on process bus can be assessed.
