Aerodynamic Model: WTGAR_A and WTARA1

In PTI: WTARA1 is the same as WTGAR_A model.

Following checks and corrections are applied during Validation and AutoCorrection.

  • If Ka = 0 then Error is created because Ka > 0.
  • If Theta < 0 then Error is created because That >= 0.

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
