Machine Model: REGFM_C1

Following checks and corrections are applied during Validation and AutoCorrection.

• The following parameter pairs should have a maximum value that is positive and a minimum value that is negative:
  DEmax/DEmin, DPDmax, DPDmin, Dwmax/Dwmin, DPGFMmax/DPGFMmin
  If both values are positive, then we will assume the minimum value should have had a negative sign.
  If both values are negative, then we will assume the maximum value should have had a positive sign.
  If the Max < 0 AND Min > 0, then we will assume the numbers have been entered backwards and we will swap the values.
• The following parameter pairs should have a maximum value that is greater or equal to than the minimum value:
  PcmdGFLmax/PcmdGFLmin, QcmdGFLmax/QcmdGFLmin
  If the Max < Min then the values will be swapped by the Auto Correction.
  
• 0.04 <= Xe <= 0.40. Any value outside this range will be set to the edge of this range
• 0.0 <= Re <= 0.25*Xe. Any value outside this range will be set to the edge of this range
• H >= 0.1. Any value less than 0.1 will be treated as 0.1
• dbVL1 represent low side deadbands which should always be negative. We will assume a parameter equal to the negative of the absolute value entered.
• dbVH1 represent high side deadbands which should always be positive. We will assume a parameter equal to the positive of the absolute value entered.
• Kf > 0, so value that is negative or zero will be treated as 1.0
• A zero or negative Ifaultmax is interpreted as ignoring the limit
• For TVr, TVSM, Twr, Twm, TVf, TPf, and TIf time constant, any value less than Mult*TimeStep will be modified. If less than 0.5*Mult*TimeStep will be set to 0.0, otherwise it will be increased to Mult*TimeStep.

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
