Stabilizer Model: WTGPT_A and WTPTA1

 

Following checks and corrections are applied during Validation and AutoCorrection.

  • If 0 < Tp < Mult*TimeStep then Tp = Mult*TimeStep
  • If RThetaMax < RThetaMin then swap the values. If RThetaMax < 0 then RThetaMax change sign to positive. If RThetaMin > 0 then change sign to negative.
  • If ThetaMax < ThetaMin then swap the values.

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
