Following checks and corrections are applied during Validation and AutoCorrection.

• f_cut must be greater than 0. If true, deadband will be ignored.
• For Param T4, T5, T6 and T1 then If 0.0 < Param < 0.5*Mult*TimeStep then Param = 0, ElseIf 0.5*Mult*TimeStep < Param < Mult*TimeStep then Param = Mult*TimeStep
• For Param Kls, Kp, Tn, Kd and Td then If 0 < Param < Mult*TimeStep then Param = Mult*TimeStep
• If Pmax< Pmin then swap the values.

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

Following treatment is handled during the transient numerical simulation

• If P > Pmax, then Pmax = P limits or if P < Pmin, then Pmin = P
