Bug Fixes

  • Transient Stability: For the CHSVCT SVC model for switched shunts, when setting Bmax, Bmin, Bfmax, and Bfmin to 0.0, the software automatically determines those values from the power flow data by summing up the available capacitors and basing Bmax and Bfmax on this sum and summing up the reactors to set Bmin and Bfmin. There was a bug that resulted in an error because we were not properly converting this value to per-unit on the SVC MVABase and were instead using the system base. This error has been fixed.
  • Transient Stability: Fixed enforcement of the non-windup limit on the svsmo3 model for the Ki/s state
