Bug Fixes

  • Case Information Displays: The Multi-section Line case information display would not allow use of Paste functionality. This has been fixed.
  • Transient Stability: A PWB file containing a PlayIn model could not be closed when exiting Simulator or loading a new case. This has been fixed. This bug was introduced in the March 19, 2014 patch.
  • Transient Stability: Updates were made to WT1G and WT2G default parameters.
  • Transient Stability: When clicking to insert a new type of model on the generator dialog, it is possible that there are no available models allowed. For example, for a WT1G (type 1) wind turbine then no exciter (electrical) model is allowed. Previously this would cause an "index out of range" error. It will now show a dialog indicating that "None available for this machine type".
  • Transient Stability: Added checking of Vbmax to the EXST3A model.
  • Transient Stability: In the Plot Designer portion of the transient stability dialog, when right-clicking on the list of plots and choosing "Generate Selected Plot", Simulator would not properly convert the @CtgName magic string into the name of the active contingency. This works when opening the plot in other ways, and it will now work via the right-click menu as well.
  • Transient Stability: Added ability to read the TIOCRS model from the DYD format.
  • Transient Stability: When showing transient stability model parameters in a case information display or when writing to an auxiliary file, Simulator will ALWAYS show 7 significant digits (excluding trailing zeros). Therefore, the user input for number of decimal places is always ignored.
  • Transient Stability: Fixed bug in TIOCRS model when used with a transformer on the "FROM" Bus. There was an error in converting the AMP pickup value which is now fixed. Would only matter for a transformer because the "CurrentBase" is different on each end of those branches.
  • User Interface Dialogs: Modified how the Initial Directory of the Open Case Dialog is handled when launching Simulator using a Short Cut and the Windows short cut setting for "Starts In". Simulator will now make sure that the first time the Open Case dialog is brought up it will start in the directory specified by "Starts In". Windows behavior changes in Windows Vista or Windows 7, so users switching from Windows XP will appreciate the behavior so it matches the behavior from Windows XP.
  • User Interface Dialogs: Fixed a bug that would not allow using the Enter key after editing a cell in a grid. This could cause dialogs containing grids to close instead of simply exiting the grid cell. This could also cause access violations.
  • User Interface Dialogs: Auxiliary File Export Description blocks allow specifying a special Use Selected filter. This was not working but has been fixed.
  • User Interface Dialogs: The Dynamic Formatting dialog now allows easier access to formatting any Object Type that is available in Simulator.
