Bug Fixes

  • Auxiliary Files (SCRIPT and DATA Sections): In an unusual situation, when deleting a branch connected to a star bus of a three-winding transformer, an access violation or reference notification error could occur. This has been fixed.
  • GIC: Fixed bug with writing and reading *.gic files.
  • GIC: Updated GIC handling of Earth Resistivity models. Also fixed some bugs and added a GIC Earth Region Set dialog.
  • GIC: Minor change so with GIC regions if there are no lat/lon values the fields are blank.
  • Transient Stability: Modified how VHVDC_A1 is initialized when KiVac1w = 0. Also fixed bug in derivative of state related to KiIac1w
  • Weather: When using the Save to Aux button on a branch options dialog and the branch is a transformer, transformer fields will be included in the aux file.
