Governor Model: WT3T1

 

Following checks and corrections are applied during Validation and AutoCorrection.

  • If 0.0 < H < Mult*TimeStep then H = Mult*TimeStep
  • Freq1: If 1/Freq1 < TwoMassMassFrequencyMultiplier*TimeStep. We will treat as a one-mass model instead.

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
