Machine Model: REGC_C

 

Following checks and corrections are applied during Validation and AutoCorrection.

  • If Tfltr < 4*TimeStep then Tfltr will use 0.0
  • If Tg < 4*TimeStep then Tg will use 4*TimeStep, and if Tg > 0.2 then Tg = 0.2

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
