Features and Improvements

  • Sensitivity Calculations: Greatly increased the speed of calculating multiple element TLR sensitivities.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): Fixed access violation caused when calling MergeLineTerminals() with no branches actually meeting the filter. This will now simply do nothing instead.
    • File Formats: Fixed potential error when reading an PTI *.seq file for sequence data. It was possible for the transformer zero sequence impedance to not properly read from this file.
    • Oneline Diagrams: Fixed error with anchoring of transmission line objects after saving some oneline diagrams.
    • PV and QV Curve (PVQV) Tool: Fixed problem with plotting base case values on the horizontal axis. Need to determine plot points based on a common nominal shift and can't assume that there will be the same number of points in a scenario and the base case results.
    • Transient Stability: Fixed error when plotting either 7 or 10 subplots on a single plot. The subplots were not laid out properly.
