Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Added another default parameter to the DiffFlowWriteCompleteModel script command called IncludeClearPowerFlowSolutionAidValues. By default this is YES. When set to YES the ClearPowerFlowSolutionAidValues script command is included in the auxiliary file saved from the case differences.
  • Difference Case Tool: When saving the Complete Model from the Preset Topological Differences from Base Case dialog, there is now an option to "Include ClearPowerFlowSolutionAidValues Script Command" that is checked by default. When checked this script command is included in the auxiliary file saved from the case differences. This script command was always included prior to this option being added.
  • Difference Case Tool: Modified the following generator fields so they are part of the Difference Case tool comparison: FuelType, FuelTypeCode, FuelTypeInteger, and FuelTypeEPC, UnitTypeInteger, and UnitTypeEPC.
  • File Formats: Added ability to read the H6E governor model from a DYD file. Removed the ability to define H6B and H6BD models from DYD models as those models are obsolete and were never used in any cases PowerWorld had previously seen. The H6E replaced this model.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): Allow fields specified with the SendToExcel script command to include user-specified digits and rod.
    • Auxiliary Files (SCRIPT and DATA Sections): Fixed bug reading ATC Extra Monitor records from auxiliary files if the objects are identified by label.
    • Difference Case Tool: When using an AUX Export Format when saving a difference case auxiliary file, the section for renumbering three-winding transformer star buses was being included even if the three-winding transformer object type was not included in the AUX Export Format. This has been fixed so that this section will be excluded if choosing not to include three-winding transformers.
    • General: Fixed a bug where advanced sorting was not properly parsing date-time strings.
    • GIC: Fixed bug in the calculation of the GIC line voltages using a non-uniform field.
    • Transient Stability: Modified plots so that when hovering over the legend entries it doesn't highlight them.
