Plant Controller: VAR1

 

Following checks and corrections are applied during Validation and AutoCorrection.

  • If VREFmax < VREFmin then swap the values.

Mult represents the user-specified value Minimum time constant size as multiple of time step option on the Validation page of the Transient Stability Dialog

TimeStep represents the integration time step being used as described on TimeStep

Following treatment is handled during the transient numerical simulation

  • If VADJ > VREFmax, then VREFmax = VADJ limits or if VADJ < VREFmin, then VREFmin = VADJ
