Protection & IEC 61850 communications
Values below are derived from the steady-state benchmark model. This page does not exchange MMS or GOOSE frames, run relay settings, or connect to real IEDs.
Bus measurements refresh when the AC power flow is solved.
No trip or interlocking messages are transmitted or evaluated.
No PTP clock, station clock, or time-quality source is configured.
Relay types are illustrative; settings, coordination, and trips are not simulated.

Switching changes the steady-state network model; protection and relay behavior are not simulated without settings.
ANSI/IEEE-style conceptual arrangement. Bus connections follow the IEEE 39-bus case; bay equipment placement is illustrative and is not an as-built switching or protection drawing.
