Governor Model: GPWSCC

Following checks and corrections are applied during Validation and AutoCorrection.

• If 0.0 < Bturb < Mult*TimeStep then Bturb = 0
• If 0.0 < Tturb < Mult*TimeStep then Tturb = 0
• If 0.0 < Td < 0.5*Mult*TimeStep then Td = 0, ElseIf 0.5*Mult*TimeStep < Td < Mult*TimeStep then Td = Mult*TimeStep
• If 0.0 < Tt < 0.5*Mult*TimeStep then Tt = 0, ElseIf 0.5*Mult*TimeStep < Tt < Mult*TimeStep then Tt = 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 0.0 < Tp < 0.5*Mult*TimeStep then Tp = 0, ElseIf 0.5*Mult*TimeStep < Tp < Mult*TimeStep then Tp = Mult*TimeStep
• If Velopen < Velclose then swap the values. If Velopen < 0 then Velopen change sign to positive. If Velclose > 0 then change sign to negative.
• If Pmax < Pmin 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

Following treatment is handled during the transient numerical simulation

• If GV > Pmax , then Pmax = GV or if GV < Pmin , then Pmin = GV
