Features and Improvements

  • Case Information Displays: Added fields for a generator to show the minimum and maximum points for MW and Mvar for a reactive capability curve.
  • Data Checks: DataChecks could be defined for any transient stability model object and viewed in the special DataCheck summary dialog inside PowerWorld Simulator, however the fields for viewing results of data check for a stability model were not available for use in other displays or via scripting. This has been fixed.
  • File Formats: When reading and writing transformer records in the EPC file will now recognize a negative "type" as an indication that control on this device is disabled.
  • Transient Stability: Modified the new REGC_C model so that the network equations use the PLL angle for the network to model reference transformation. Previously the PLL angle was used for doing the transformation for modeling the current controls, but not the network equations.
  • Bug Fixes

    • Available Transfer Capability (ATC) Tool: Fixed bug that might not allow pasting changes from Excel into ATC line rating change scenarios because the key fields could not be identified when using column headers to identify fields.
    • Available Transfer Capability (ATC) Tool: Fixed bug that would remove the Label field in Line and Generator ATC Scenario case information displays when pasting in new data.
    • Data Checks: DataChecks could be defined for any transient stability model object and viewed in the special DataCheck summary dialog inside PowerWorld Simulator, however the fields for viewing results of data check for a stability model were not available for use in other displays or via scripting. This has been fixed.
    • GIC: For GIC corrected the electric field V/mile and V/km values being flipped.
