Features and Improvements

  • Case Information Displays: Modified so that the Selected field can be edited or toggled while iin Difference or Base Case mode for the Difference Flows tool.
  • Contingency Analysis Tool: Added an option to auto-insert contingencies and name them by label.
  • Fault Analysis: Added an option to auto-insert faults and name them by label.
  • Oneline Diagrams: While in Run Mode, left clicking on a bus name or number field will open the Bus View for that bus.
  • Sensitivity Calculations: Added LODF Screening tool to screen single line contingencies by LODF magnitude or loading. Pairs of contingencies can be created from contingencies that are deemed to be significant based on screening thresholds. Purpose is to create a more manageable list of contingencies rather than run all pairs of single contingencies.
  • Transient Stability: Added an option to auto-insert transient contingencies and name them by label.
  • User Interface Dialogs: In Set Selected from Network Cut tool, added option to prompt user asking if they would like to initialize the Selected field.
  • User Interface Dialogs: Added Line length information on Branch Information dialog while in Run mode.
  • Bug Fixes

    • Contingency Analysis: When using one of the linear solution techniques or when solving in dc power flow mode, the impact of contingencies that closed lines was not being correctly calculated. This has been fixed.
    • User Interface Dialogs: When using the equivalencing tool to save out a portion of the system to a PWB file, an error could result when appending the file to another case if transient stability data existed in the original system. Transient stability data is now currently not stored with the portion of the system saved to file.
