Stabilizer Model: WT1P_B
AutoCorrection Properties
Following checks and corrections are applied during Validation and AutoCorrection.
- If 0.0 < Tr < 0.5*Mult*TimeStep then Tr = 0, ElseIf 0.5*Mult*TimeStep < Tr < Mult*TimeStep then Tr = Mult*TimeStep
- If 0.0 < T < 0.5*Mult*TimeStep then T = 0, ElseIf 0.5*Mult*TimeStep < T < Mult*TimeStep then T = 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
