value
-100 Minimum expected load
100 Maximum expected load
3000 Set zero point clamping to 60 MW that is, 3% of
200 MW
db Select magnitude deadband supervision
2000 Set ±Δdb=40 MW that is, 2% (larger changes than
40 MW will be reported)
60 High alarm limit that is, extreme overload alarm,
hence it will be 415 MW.
50 High warning limit that is, overload warning, hence
it will be 371 MW.
-50 Low warning limit -500 MW
-60 Low alarm limit -600 MW
1 Set ±Δ Hysteresis 20 MW that is, 1% of range
