Features and Improvements

  • Transient Stability: Added a new Injection Group transient stability model named GroupMSS.
  • User Interface Dialogs: Modified the dialog that appears offering the user the ability to add "Case Comments" when choosing options to Save Case, Save Case As, Save Case with Comments, or Save Case As with Comments. Previously once you got to that dialog there was no way to "Abort the Save". Hitting the X in the upper right would just skip adding the comment but you would still save the case. There are now separate buttons to Add a comment, Skip adding comment, and Abort Save all together. Also removed the X in the upper-right of this dialog to force the user to choose one of the buttons making it very clear what is desired.
  • Bug Fixes

    • Case Information Displays: Fixed an access violation that could result when using the option to Export Case Object Fields related to the new ModelPlane object
    • Transient Stability: Bug fix in Modal Analysis for catching exception during floating point overflow, which happens rarely, but typically while using a large time window, or a time window which has a "discontinuous" signal (like when a generator opens up, causing a sudden change)
