Features and Improvements

  • File Formats: When writing out an EPC file, the generator baseload flag is now written as a 2 if also using the option that the baseload flag means to prevent post contingency AGC response and post contingency AGC response is being prevented.
  • General: Testing
  • Oneline Diagrams: Added option to convert a background line to a multi-section line.
  • Oneline Diagrams: New multi-section lines can now be created by adding a new multi-section line object to a oneline diagram.
  • Oneline Diagrams: Model Conditions and Model Filters can now be selected for Generic Model Fields on a oneline diagram.
  • Transient Stability: Added two new fields with the transient contingency results to report the total load and total gen tripped during simulation of that contingency.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): When using the SaveData script with CSVColHeader file type and saving multiple TLR results, the column headers are now properly displayed for the multiple TLR elements instead of displaying a generic header.
    • Case Information Displays: When viewing the Bus case information display, switched shunt MW information was not being displayed. This has been fixed.
    • File Formats: When loading in an EPC file, the IDs of bus shunts (Bus Shunt Fixed Control Mode in Simulator) will be changed to new unique IDs if SVDs (non-Bus Shunt Fixed Control Mode in Simulator) are read in with the same ID at the same bus. Previously, switched shunts with the same ID at the same bus would just be overwritten. SVDs with the same ID can still overwrite each other and Bus Shunt Fixed with the same ID can still overwrite each other.
    • General: When using Difference Flows and viewing the Difference Case, the MW generation for a bus was showing the sum of the generation for the two cases instead of the difference. This has been fixed.
    • General: When creating an equivalent, owners were not getting updated. This has been fixed.
    • Sensitivity Calculations: When using the SaveData script with CSVColHeader file type and saving multiple TLR results, the column headers are now properly displayed for the multiple TLR elements instead of displaying a generic header.
    • Time Step Simulation: When saving results to a CSV file, the results were all being saved to a single line in the file. This has been fixed.
    • Transient Stability: Fixed a bug on the Transient Stability dialog if you were on the Simulation page. If you selected the Definitions or Violations tab, the Control tab was shown without being refreshed correctly.
    • Transient Stability: Fixed some bugs with creating dynamic equivalents in cases with phase shifters.
    • Transient Stability: When creating dynamic equivalents, set the voltage setpoint for dynamic equivalent generators.
    • Transient Stability: When loading in contingency line elements from an auxiliary file and you had an event that opened or closed a line at the near end and the far end, the second event was not loading. This has been fixed.
    • Transient Stability: When a single relay sends multiple tripping amounts at the same time at the same time delay, the total amount that is tripped is now reported as a transient event.
    • Transient Stability: Fixed an access violation that could occur when showing the Results table that included generators that are open.
