Selectivity as Code: Closing the Loop Between PowSyBl and SEAPATH
summary
Claims that PowSyBl can act as a grid engine feeding Scc and Icc into a protection test chain are demonstrated by closing the loop into SEAPATH: PowSyBl exports line and source strength, an injector streams IEC 61850 SV and GOOSE from comtrade or pcap files, and a virtual distance relay on Cpass runs campaigns end‑to‑end. A full campaign plays in ~30 minutes, injector samples at 4,000 kHz, zone‑one trips occur ~12 ms (example 37 ms reported), and zone delays (150 ms, 600 ms) match expected selectivity.
