Features and Improvements

  • Case Information Displays: Added dc line status as a field that is available with the dc line case information display.
  • Case Information Displays: Custom expressions and custom string expressions can now be deleted from their respective case information displays.
  • File Formats: Added the ability on the File Formats Environment Options of the Simulator Options dialog to export a set of a Pattern files which describe all the fields that Simulator knows how to read from the hdbexport CSV files.
  • Power Flow Solution: When using the bus integer field "Priority" to influence the slack buses chosen, Simulator was using that integer even if the bus did not have any CLOSED generators. This meant that if the bus with the highest priority integer did not even have a closed generator then the island would end up being disconnected because no viable slack bus was chosen. This has been fixed so that any bus without any closed generation is ignored in the choice of a slack bus regardless of the Priority specified.
  • Transient Stability: Improved the network boundary convergence for handling current injection machine models
