Governor Model: WESGOV and WESGOVD
Following checks and corrections are applied during Validation and AutoCorrection.
- If 0.0 < Ti < Mult*TimeStep then Ti = Mult*TimeStep
- If 0.0 < T1 < 0.5*Mult*TimeStep then T1 = 0, ElseIf 0.5*Mult*TimeStep < T1 < Mult*TimeStep then T1 = Mult*TimeStep
- If 0.0 < T2 < 0.5*Mult*TimeStep then T2 = 0, ElseIf 0.5*Mult*TimeStep < T2 < Mult*TimeStep then T2 = 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
