Stabilizer Model: STBSVC
Following checks and corrections are applied during Validation and AutoCorrection.
- If 0 < Ks1 < Mult*TimeStep then Ks1 = Mult*TimeStep
- If 0 < Ks2 < Mult*TimeStep then Ks2 = Mult*TimeStep
- If 0 < T9 < Mult*TimeStep then T9 = Mult*TimeStep
- If 0 < T12 < Mult*TimeStep then T12 = Mult*TimeStep
- If 0 < T14 < Mult*TimeStep then T14 = Mult*TimeStep
- If 0.0 < T7 < 0.5*Mult*TimeStep then T7 = 0, ElseIf 0.5*Mult*TimeStep < T7 < Mult*TimeStep then T7 = Mult*TimeStep
- If 0.0 < T10 < 0.5*Mult*TimeStep then T10 = 0, ElseIf 0.5*Mult*TimeStep < T10 < Mult*TimeStep then T10 = Mult*TimeStep
- If Vscs = 0 then Vscs = 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
