Governor Model: WT4T

Following checks and corrections are applied during Validation and AutoCorrection.

• If dPmx < Pmnthen swap the values. If dPmx < 0 then dPmx change sign to positive. If Pmn> 0 then change sign to negative.
• If 0.0 < Tpw < 0.5*Mult*TimeStep then Tpw = 0, ElseIf 0.5*Mult*TimeStep < Tpw < Mult*TimeStep then Tpw = Mult*TimeStep
• If 0.0 < Tf < 0.5*Mult*TimeStep then Tf = 0, ElseIf 0.5*Mult*TimeStep < Tf < Mult*TimeStep then Tf = Mult*TimeStep
• If Kip > 1/(Mult*TimeStep) then Kip = 1/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
