Bug Fixes

  • Auxiliary Files (SCRIPT and DATA Sections): Many ObjectTypes in AUX files have fields that are a string representing a reference to another object. Those strings have the format of "ObjectType KeyField1 KeyField2 etc". For example, a branch may be represented by the following string: "BRANCH 12345 98765 '12'" . This string is the word BRANCH followed by a SPACE, then integer bus number, followed by a SPACE, and so on. The syntax calls for using a SPACE character as the delimiter between key fields. Users however sometimes edit AUX files in a text editor and may use a TAB character instead of a SPACE. PowerWorld's AUX file parser will now handle a TAB character in those locations and treat them just like a SPACE character.
  • Transient Stability: Fixed a bug when closing a generator in transient stability when no governor was available in the generator. This was causing an access violation. This bug was fixed.
