Switched Shunt Model: CHSVCT
AutoCorrection Properties
Following checks and corrections are applied during Validation and AutoCorrection.
- Tw, T2 and Tm2 must be great than Mult*TimeStep. If they are not, they are set to Mult*TimeStep
- T4 and Tm4 can be zero. If they are less than 0.5*Mult*TimeStep they are set to zero. If they are between 0.5*Mult*TimeStep and Mult*TimeStep they are rounded up to Mult*TimeStep.
- If Vsmax < Vsmin then swap the values.
- If Bfmax < Bfmin then swap the values.
- If Bmax < Bmin then swap the values.
- SMF Bus must be one of the terminal of the SMF Branch. If it is not, then SMF Bus is treated as the from bus of the SMF Branch.
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
