Machine Model: MOTOR1
AutoCorrection Properties
Following checks and corrections are applied during Validation and AutoCorrection.
- If H < 0.1, then H = 0.1
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
