Features and Improvements

  • Case Information Displays: Modified the Column Metrics to show more information.
  • File Formats: When writing out an EPC file, no longer check to see if there is a generator with a closed status at a bus to identify it as type 2 or -2.
  • File Formats: When writing out buses to an EPC file and specific voltage ratings for a bus have not been specified, write 1.1 as the default for max ratings and 0.9 for min ratings.
  • Oneline Diagrams: New Oneline Script Command called InsertConnectedBuses that will add connected buses to a display object bus in a online diagram. The input parameter of the script command will be the bus where the user wants to insert the connected buses.
  • Transient Stability: Modified the format for transient stability plot axis numbers so that for values below 100,000 they will continue showing values in the format 30,000 instead of showing 3.0E4.
  • Transient Stability: Added @CTGEVENTSUSER keyword that can be used in transient stability plot title block to display the transient events that are user defined, i.e. the Transient Contingency Elements. Events with other event levels will not be displayed.
  • Transient Stability: DER_A model is now read from a dyd file
  • User Interface Dialogs: Modified the Keyboard Shortcuts features so that they can load AXD files into the presently active oneline
  • Bug Fixes

    • Case Information Displays: For case information display columns shown an color entry, the ability to flood fill the color using the small rectangle in the bottom left of the cell was not working. This has been fixed.
    • Contingency Analysis: The option found on contingency violation case information menus to Create Contingent Interface for Selection was disabled even for some allowed contingency actions. This has been fixed.
    • Difference Case Tool: When writing an auxiliary file with Difference Case added objects, new star buses of three-winding transformers were not being written. This has been fixed.
    • GIC: Fixed issues associated with loadiing JSON electric field data files. Also added ability to automatically update the time-series data when the files are loaded.
    • Oneline Diagrams: Fixed bug when pasting objects with the option to create new model objects. If prompted, the user selected option was working.
    • Transient Stability: Fixed initialization of the H6E governor integrator state when Fd<>0 and Kp<>0.
    • Transient Stability: Modified transient plots so that the format of the label text for horizontal axis and vertical axis labels do not appear with scientific notation if the actual range of the values is very narrow. Previously it was basing the label format only on the values.
