Stabilizer Model: PSS3B

Following checks and corrections are applied during Validation and AutoCorrection.

• If 0 < Tw1 < Mult*TimeStep then Tw1 = Mult*TimeStep
• If 0 < Tw2 < Mult*TimeStep then Tw2 = Mult*TimeStep
• If 0.0 < Tw3 < 0.5*Mult*TimeStep then Tw3 = 0, ElseIf 0.5*Mult*TimeStep < Tw3 < Mult*TimeStep then Tw3 = Mult*TimeStep
• If 0.0 < T1 < 0.5*Mult*TimeStep then T1 = 0, ElseIf 0.5*Mult*TimeStep < T1 < Mult*TimeStep then T1 = Mult*TimeStep
• If 0.0 < T2 < 0.5*Mult*TimeStep then T2 = 0, ElseIf 0.5*Mult*TimeStep < T2 < Mult*TimeStep then T2 = Mult*TimeStep
• If Vstmax < Vstmin then swap the values. If Vstmax < 0 then Vstmax change sign to positive. If Vstmin > 0 then change sign to negative.

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
