Load Characteristic Model: LD1PAC

Following checks and corrections are applied during Validation and AutoCorrection.

• If 0.0 < Tv < 0.5*Mult*TimeStep then Tv = 0
  ElseIf 0.5*Mult*TimeStep < Tv < Mult*TimeStep then Tv = Mult*TimeStep
• If 0.0 < Tth < 0.5*Mult*TimeStep then Tth = 0
  ElseIf 0.5*Mult*TimeStep < Tth < Mult*TimeStep then Tth = Mult*TimeStep
• If 0.0 < Tf < 0.5*Mult*TimeStep then Tf = 0.0
  ElseIf 0.5*Mult*TimeStep < Tf < Mult*TimeStep then Tf = 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
