Bug Fixes

  • General: In some situations when the recently opened files list in PowerWorld Simulator was cleared out when it should not have been. This has been fixed.
  • Oneline Diagrams: Fixed an "Invalid pointer operation" error that could occur when opening a PWD file that contains substation, owner, or balancing authority objects with the same number key field as a different object type within these three object types. If choosing to open a oneline using either secondary key fields or labels instead of numbers, mis-identification of objects within these three types might occur if they have the same number. This can be fixed by opening the oneline with a case where the numbers for these types of objects on the oneline match the case and saving the oneline with this patch or later.
  • Transient Stability: Fixed a bug an issues with Transient Stability Plots when saving the data using the Show/Save Selected Plot Data. The Save to... options were not working properly when saving certain data that is calculated from other fields such as Bus Voltage in KV. Also it wasn't working properly when the data contained RAM and Hard drive data in the plot. Those issues were corrected. This change also corrected the TSGetResults script commands and TSGetContingencyResults SimAuto function for the same issues.
  • Transient Stability: Fixed error when using the "Copy All Charts and Title Block" when either the right or left memo contained multiple lines of text, then only the last line of text was being written to the image. This also impacted memos with multiple lines of text when exported to an image. The dialogs shown in the user interface were always correct, but the images are now also correct.
