Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Added Length function that can be used with expressions. This function takes a string as a parameter and returns an integer.
  • Case Information Displays: Added Case Path as an available field for the PWCaseInformation object type.
  • Case Information Displays: Added Bus and Bus Group fields to show the generator MW range (total, up, down). There are three options: either 1) the AGCable generators that are online, 2) all online generators, 3) all generators.
  • Case Information Displays: Added fields to show switched shunt values aggregated at the bus, area, zone, substation, and superarea level.
  • GIC: Added Bus GIC field to show the GIC related losses allocated to the bus. These include the losses from the implicit GSUs and the other transformers. To avoid double counting the explicit transformer losses, the losses are allocated to the transformer's from bus only. Modified in v23 and v22.
  • GIC: Added showing GIC electric field magnitude and angle on the substation dialog. Also, the code now transfers back the substation electric field magnitude and angle from TS (this would mostly be used for EMP analysis).
  • GIC: In GIC I modified the code that calculates the substation and line electric field values for the non-uniform fields to be more efficient. This should make the Setup Time Varying Series function faster (which is called whenever a b3d file is loaded).
  • Oneline Diagrams: Added support for GDV two field rectangle objects. These are similar to the kites, except using rectangles. The objection are either top and bottom values, or left and right values.
  • Transient Stability: Added new injection group command to open or close all devices in the injection group.
  • Transient Stability: Added TS Interface Open and Close commands. These commands open or close all the branches in the interface.
  • Transient Stability: Added the ability to make plots from Result Analyzer Signal Violations. See "Make New Plot..." in the right-click local menu.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): Fixed bug that would not identify CustomExpressionStr objects with the correct key field identifier. The result was that multiple string expressions for the same object type would all have the same key field resulting in only one being created when loaded from an aux file.
    • File Formats: PSSE RAW file generator records will be written out with WMOD = 1 when the FuelType =SUN (Solar) OR Unit Type = PV (Photovoltaic) within Simulator
    • GIC: Added read/write support for the EMP E1 fields (so they don't get lost in load/saving with v22)
    • GIC: Added code to prevent an exception error when the GIC Form is close while the transient stabilty simulation is running.
    • Oneline Diagrams: Fixed bug when trying to delete points from the Contour Symbol Dialog.
