Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Added script command CTGSaveViolationMatrices.
  • Contingency Analysis Tool: Contingency Violation Matrices tables now allow access to the fields associated with the object type displayed in the row of the table.
  • File Formats: Added reading the ELIGIBLE field from the LNLIM, XFLIM, and ZBLIM records from the hdbexport file. If this field is not in the file or if it is TRUE then we set the Monitor field in Simulator to YES. If the ELIGIBLE field is in the file and FALSE then we set the Monitor field to NO.
  • General: Added fields for three-winding transformers to show MonitorPri, MonitorSec, MonitorTer, LimitSetPri, LimitSetSec, and LimitSetTer.
  • Transient Stability: Initial implementation of generator plant controller model REPC_B.
  • User Interface Dialogs: Documentation images of three-winding transformer base conversions are now shown on the three-winding transformer dialog.
  • User Interface Dialogs: Added new menu item under Onelines Ribbon Tab-->List Display to show the list of Geo Data View Styles.
  • Bug Fixes

    • General: Modified the Bypass field for a branch to be either YES or NO. Previously it would show "Bypassed" or "Not Bypassed" which was cumbersome
    • Oneline Diagrams: If opening multiple onelines containing the same Geo Data View Styles, the styles could become undefined causing access violations or geo data view objects not to display. This has been fixed.
    • Oneline Diagrams: GIC sparkline var loss values are now reported in Mvar rather than per unit.
    • Oneline Diagrams: When exporting a KML file, the bus name used is just the Name of the bus instead of the LongName field.
    • Simulator Automation Server (SimAuto): "ALL" busloc qualifier is now allowed for the GetParametersMultipleElement/FlatOutput/Rect functions.
    • Transient Stability: Fixed error in svsmo1 and svsmo2 when Kp > 0 and Ki > 0.
    • Transient Stability: Fixed some PI blocks error in parameters with the Kp/Ki term been in the wrong order. Affected models are svcals, svsmo3, UEL1 and UEL2.
    • Transient Stability: Fixed issues with enforcing field limits on SEXS_PTI and SEXS_GE.
    • Transient Stability: Added subintervals for SVSMO1, SVSMO2, and SVSMO3 if inv(Kp)*Ki > 1/(2*time step).
