Bug Fixes

  • Auxiliary Files (SCRIPT and DATA Sections): Assigning data objects to supplemental data might not identify the correct supplemental data when assigning through AUX files.
  • File Formats: Fixed a bug that was occurring when exporting sequence data to SEQ files. Writing out the zero sequence impedances for three winding transformer devices was incorrect for newer SEQ files that allow two digit connection codes for transformers. Older SEQ files with single digit connection codes were unaffected.
  • Oneline Diagrams: Supplemental Data Field display objects were not supported in AXD files. They are now.
  • Oneline Diagrams: Supplemental Data Geo Data View objects were not supported in AXD or PWD files.
  • Oneline Diagrams: Fixed bug saving Geographic Data View Supplemental Data objects to a PWD file and being able to display these objects when the PWD is opened.
  • Transient Stability: Corrected bug with WT3E and WT3E1 that had an incorrect path with vltflg=0. For this case the connection should be directly to state1. This only impacted models with vltflg=0, which only occurred in the East grids, not the WECC. This did fix a lot of initial limit violation changes.
