Following checks and corrections are applied during Validation and AutoCorrection.

• If At <= 0 then At = Mult*TimeStep
• If 0.0 < Tt < 0.5*Mult*TimeStep then Tt = 0, ElseIf 0.5*Mult*TimeStep < Tt < Mult*TimeStep then Tt = Mult*TimeStep
• If 0.0 < Tp < 0.5*Mult*TimeStep then Tp = 0, ElseIf 0.5*Mult*TimeStep < Tp < Mult*TimeStep then Tp = Mult*TimeStep
• If 0.0 < Tw < Mult*TimeStep then Tw = Mult*TimeStep
• If Pmax < Pmin 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 GV > Gmax , then Gmax = GV or if GV < Gmin , then Gmin = GV
