Features and Improvements

  • GIC: Updated GIC code to better handle intermediate buses of multi-section lines. If the intermediate bus does not have any latitude/longitude specified then we will estimate the location using branch resistance values.
  • User Interface Dialogs: Updating the multi-section line dialog. There is now a regular listing of the buses in the object.
  • Bug Fixes

    • Contingency Analysis: When saving a PWB file and the contingency analysis dialog was open, the options as set on the dialog were not always being saved to the PWB file. This has been fixed.
    • File Formats: When reading an EPC file and SVCs are allowed to control fixed shunts the linking to the fixed shunts was not being done correctly. This has been fixed.
    • Oneline Diagrams: Fixed a bug where the Snap To Grid setting was continually being reset to True
    • Power Flow Solution: When multiple lines that are not in series are closed and they have common bus terminals, angle smoothing does not work correctly. When this situation is encountered voltage estimates will be done instead on the buses that are involved in the line closures
