Features and Improvements

  • Transient Stability: Added REEC_E Exciter Transient Model.
  • Transient Stability: Improved Algebraic Network Boundary equation solutions at the time of fault or fault clearing for the REGC_B, REGC_C and DER_A machine models.
  • Bug Fixes

    • Case Information Displays: Fixed bug with the wrong object type being used in the Advanced Filter dialog when the dialog is opened using the Find button on the Filter toolbar.
    • File Formats: When loading a DYD file if duplicate _cmp_der_a or _cmp_dgpv with the same data number (such as -103) were read an error occurred. This has been fixed so that whatever the final entry read will be maintained.
    • Transient Stability: For both the PlayInGen and InfiniteBusSignalGen machine models, when Rth was not 0 there was a bug. This has been fixed.
