Bug Fixes

  • Transient Stability: Prevent storing transient limit monitor violations twice to a PWB file. If older files are read where there is the possibility of multiples of the same violation being stored, check for and remove any duplicates.
  • Transient Stability: Fixed error in keeping track of the transient contingency results for "Total Gen MW Tripped". Value was being calculated by multiplying the generator per unit power by the SYSTEM MVABase instead of the machine MVA Base.
  • Transient Stability: Fixed potential error when using a negative END time in a transient stability simulation.
  • Transient Stability: The Transient Stability Dialog was preventing a start or end time which was negative. You could specify a negative time in the case information display showing multiple contingencies, but the edit box for Start and End Time on the dialog was always limiting those values to between 0 and 9999. This has been fixed so negative times may be entered.
