Stabilizer Model: PSSSH
Following checks and corrections are applied during Validation and AutoCorrection.
- If 0 < Td < Mult*TimeStep then Td = Mult*TimeStep
- If 0 < T1 < Mult*TimeStep then T1 = Mult*TimeStep
- If 0 < T2 < Mult*TimeStep then T2 = Mult*TimeStep
- If 0 < T3 < Mult*TimeStep then T3 = Mult*TimeStep
- If 0 < T4 < Mult*TimeStep then T4 = Mult*TimeStep
- If Vsmax < Vsmin then swap the values. If Vsmax < 0 then Vsmax change sign to positive. If Vsmin > 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
