Features and Improvements

  • Case Information Displays: Added ability to use other object type filters with the GenVarLim object.
  • File Formats: When loading the hdbexport file, modified to automatically add two labels to each transmission line. One label starts with the "from" substation name and the other label starts with the "to" substation name.
  • Transient Stability: Added support for storing interface MW, Mvar, and MVA flows as part of the transient stability results.
  • Transient Stability: Added ability to show the number of elements in a Transient Contingency.
  • Transient Stability: Modified the Transient Contingency Element Dialog to show the filter information for choosing the object by default.
  • Bug Fixes

    • Contingency Analysis: Fixed bug that would prevent creating the following object types from an Auxiliary File or by copy/paste from a spreadsheet: ContingencyElement, CTGElementBlockElement, GlobalContingencyActionsElement, PostPowerFlowActionsElement.
    • Oneline Diagrams: Fixed flashing hint windows caused by interaction between navigation arrows and oneline hints.
    • Transient Stability: Fixed bug with writing TSR files. The bug was introduced in July 2 patch.
    • Transient Stability: Some problems with access violations when running stability were encountered related to the plot designer. These should be fixed now.
    • Transient Stability: When auto-correcting the Xl value for a GENSAL, GENROU, or other synchronous machine model, the informational message had a typo indicating it was changing Xqp. This typo has been fixed.
    • Transient Stability: The auto-correction routine was not allowing the Linc value of a GAST_GE model to be near zero. This restriction has been removed.
