Machine Model: GEWTG

 

Following checks and corrections are applied during Validation and AutoCorrection.

  • fcflg:
    • If exciter is EWTGFC and model has (fcflg = 1) indicating it is a full converter model, however it is using the DFAG electrical model EXWTGE instead. Parameter fcflag changed to 0 to match this.
    • If exciter is EXWTGE and model has (fcflg = 0) indicating it is a DFAG model, however it is using the full converter electrical model EXWTG instead. Parameter fcflag changed to 1 to match this.

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
