Machine Model: WT3G

 

Following checks and corrections are applied during Validation and AutoCorrection.

  • If LVPL1 < 0 then LVPL1 = 0.0 per unit. We will ignore all low voltage power logic and treat model as though Lvplsw = 0.
  • If Td < 4*TimeStep then Td = 4*TimeStep, and if Td > 0.2 then Td = 0.2

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
