Source data: ratings and rules from control philosophy. Load MW values are simulated.
Primary LS: predictive reserve calculation.
Backup LS: independent 81U/81R; thresholds and delays per transient-stability study.
Essential LS: active only on EDG supply.
ATS: transfer after delay, blocked on electrical fault/86/unavailable breaker.
