Features and Improvements

  • Transient Stability: Added more descriptive messages to Transient Events for LHVRT, LHFRT, LHSRT models configured to be in Alarm Mode. They will now show the MW of the generator from the initial condition to provide information about how much generation would have tripped if the model was not in alarm mode
  • Transient Stability: Added a new field that can be added as a column to the Transient Stability Events for "MVA Base". This field will show the generator MVA Base, load MVA, Branch Limit MVA Normal, and Switched Shunt maximum Mvar value. Events for other object types will return a blank.
  • Bug Fixes

    • Contingency Analysis: When reporting disconnected buses as violations, Simulator was using the options regarding ignoring radial buses for limit checking. The ignore radial checking was added for low and high bus voltage violations, but it is not appropriate to ignore radial buses when flagging disconnected buses. Simulator will now report these radial buses as disconnected.
    • Oneline Diagrams: Fixed bug with GDV mosaic transitioning -- it could hang when the Animation Frames was set to zero. Also, now on the transition is using the minimum of either the total time or the total frames.
