Stabilizer Model: PTIST3
Following checks and corrections are applied during Validation and AutoCorrection.
- If 0 < Tp < Mult*TimeStep then Tp = Mult*TimeStep
- If 0 < Tf < Mult*TimeStep then Tf = Mult*TimeStep
- If 0 < T2 < Mult*TimeStep then T2 = Mult*TimeStep
- If 0 < T4 < Mult*TimeStep then T4 = Mult*TimeStep
- NCL: Warning because PowerWorld has not implemented the Limit Function of this stabilizer. The limit function will be ignored.
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
