Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Can now refer to custom expression by name rather than number location of the field. Instead of using "CustomExpression:location" can now use "CustomExpresion:name". Using this option for custom expressions requires that a name be specified for the custom expression
  • Auxiliary Files (SCRIPT and DATA Sections): When saving out an entire case as an auxiliary file, the field "AllLabels" is included for each object type that allows labels and has some labels defined.
  • Auxiliary Files (SCRIPT and DATA Sections): Improved speed of loading a large number of Model Expressions or Custom Expressions from an auxiliary file.
  • Auxiliary Files (SCRIPT and DATA Sections): Allow the SaveCase script command to take special keywords as part of the filename. Simulator will replace these special strings as desired when creating the filename to save. @DATETIME will replace the keyword with the actual date an time in the format yyyymmdd_hhnnss-hhmm with the UTC offset included on the end of the time. The other special keywords @DATE, @TIME, @BUILDDATE,and @VERSION can also be used but are not as useful as the @DATETIME.
  • Case Information Displays: Show the "Disable If True in CTG Ref" and "Evaluate in CTG Ref" fields by default with the Model Condition case info.
  • Transient Stability: Add ability to right-click on a plot series trace in a transient stability plot and choose "Bus View". This will automatically open the bus view related to the object associated with the plot series.
  • User Interface Dialogs: Add an option the bottom of any dialogs System Menu for "Print" which will send an image of the dialog to the printer.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): Using the script command "Scale" with injection groups, the scaling was not functioning properly since the patch release on August 24, 2012. This has been fixed.
    • Power Flow Solution: Fixed error in how area interchange was handled when solving a DC power flow solution in a case which had transformers with non-zero magnetizing conductances.
    • Transient Stability: Fixed error in the transient stability contingency command requesting that loads within an Injection Group be opened. Previously this wasn't working properly.
