Features and Improvements

  • General: On the Tools, Connections, Determine Shortest Path Between
    1) added a tab that shows the lines that are in the path
    2) corrected the order in which the buses are shown to start at the start bus and go to the end bus, 3) on the list displays for the buses, substations, areas and zones added a local menu entry to get access to this form. Because the Buses list display already had local menu entry to another form for showing the shortest path it now has two options with the original (older) approach labeled as old. A difference with the older approach is it did include DC lines show some folks might prefer that. This old form also now shows lines.
  • Transient Stability: Changed the transient stability so when a generator is closed by default its MW setpoint is not set to zero. However the generator is taken off of AGC control.
  • Bug Fixes

    • Transient Stability: Changes associated with closing a generator in transient stability. Now they work correctly when closed at off-nominal speed. Also, AGC control is disabled when a generator is reclosed.
    • Transient Stability: Cleaning up captions for transient events when specifying to close generators.
    • Transient Stability: Fixed a bug where TS plots in a Distributed run were showing up blank if other results were not saved.
    • Transient Stability: Fixed a bug with the OEL2C that was creating an initialization problem for the exciters derivatives because it was setting the OEL output to the incorrect initial value.
    • User Interface Dialogs: Fixed errors on the Direction dialog
