Features and Improvements

  • Transient Stability: Added a message when changing, setting and ramping a load in transient stability. The message will tell the user that the Mvar also change and look our web help for more info.
  • Transient Stability: Added support to read and write ESDC2C transient model from a dyd file.
  • Bug Fixes

    • Fault Analysis: Fixed a bug calculating the phase currents on the TO side of a Delta - Grounded Wye transformer when the user put in ground impedance values for RG2 and XG2. Previously the calculation specifically for this transformer configuration was incorrectly using the RG and XG ground impedance values on the FROM side of the transformer when calculating the TO side phase currents.
    • Oneline Diagrams: Fixed a bug where gauges were not showing anything for owners if the owner only had loads assigned but no buses. Changed it to work the same as for areas, etc., that the gauges will show the load value for an owner group, even if only loads are part of the owner.
    • Transient Stability: Bug Fix for UEL1 model.
    • Transient Stability: Fixed a bug with WTGPT_A in where the Pitch was miscalculated if the Generator was controlled by a remote plant.
