Features and Improvements

  • User Interface Dialogs: Added the ability to search the Case Description using the Search Bar that can be added to the dialog.
  • Bug Fixes

    • Available Transfer Capability (ATC) Tool: When using the option to create an interface from a limiting element and contingency, three-winding transformer open and bus open contingencies are now included. A three-winding transformer contingency will add the two-winding transformers as interface contingent elements, and a bus contingency will add all branches connected to the bus as contingent elements.
    • Case Information Displays: Fixed a few bugs with the case information display search bar: (1) no longer beep when enter is pressed, (2) no longer clear selected text when enter is pressed, (3) no longer disallow the first entry after hitting enter to conduct a search, and (4) unselect last selection if new search text is not found.
    • Contingency Analysis: When using the option to create an interface from a contingency and violation, three-winding transformer open and bus open contingencies are now included. A three-winding transformer contingency will add the two-winding transformers as interface contingent elements, and a bus contingency will add all branches connected to the bus as contingent elements.
    • Transient Stability: Removed special subinterval integration for GENCLS when using Euler's method on a small case (less than 200 buses).
    • Transient Stability: For the H6E Governor model if the bgvmin is greater than 1 or less than 0 this will be treated as a warning instead of an error.
