Load Characteristic Model: CIMW

Following checks and corrections are applied during Validation and AutoCorrection.

• R1: 1) If motor is not Double Cage or Type 1, then if circuit parameters result in a Tp time constant which is too small then set R1 to a multiple of Tp/(Minimum time constant size as a multiple of time step). 2) If motor is Double Cage or type 2, then if circuit parameters result in a Tpp time constant which is too small then change the motor to single cage by setting R2 and X2 to zero only if Tpp is less than Half the Minimum time constant size as a multiple of time step, and if not just set R1 to a multiple of Tpp/(Minimum time constant size as a multiple of time step).
• R2: 1) If motor is Double Cage and Type 1, then if circuit parameters result in a Tpp time constant which is too small then change the motor to single cage by setting R2 and X2 to zero only if Tpp is less than Half the Minimum time constant size as a multiple of time step, and if not just set R2 to a multiple of Tpp/(Minimum time constant size as a multiple of time step). 2) If motor is Double Cage and Type 2, then if circuit parameters result in a Tp time constant which is too small then set R2 to a multiple of Tpp/(Minimum time constant size as a multiple of time step).

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
