Software Patches

Features and Improvements

  • Transient Stability: Adding initial draft of VHVDC_A1
  • Bug Fixes

    • File Formats: Added ability to read and write from a RAW file the transformer "Load Drop" impedance. These are read into the PowerWorld Line Drop values.
    • File Formats: Also modified reading of switched shunts, FACTS, and Bus shunts to clean up writing those back out to RAW version 35 and later which can have IDs with the shunts.
    • Oneline Diagrams: When displaying the default font size for a oneline, the value in the dialog is shown as a point size. This value was not being set correctly when using the font size that is specified with the DefDrawOneline object. This has been fixed.
