Features and Improvements

  • Case Information Displays: Owners can now be used as Secondary Filter classes ViolationCTG and LimitViol objects. This means that Owner filters can be applied to ViolationCTG and LimitViol objects now.
  • Transient Stability: Added ability to popup a dialog that shows the signal represented by the selection in the Min/Max results from RAM tables
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): When setting owner numbers and owner percent values for devices that support multiple owners, with AUX scripts like SetData/SetElseCreateData, the owner numbers were being trampled and data was not being stored as expected. This has been corrected.
    • Transient Stability: Fixed SW1 switch that was loading with the incorrect parameter on DC4C. In PowerWorld, Position A and B are 1 and 2, respectively, but in GE PSLF they are 1 and 0.
    • Transient Stability: When loading in the ESST6C model from a DYD file we now read the extra parameter SCL_Flag at the end indicating the location of the SCL input
    • Transient Stability: When loading in various DYD files with integer switches to indicate locations of OEL, UEL, Stabilizer, and SCL inputs, Fix treatments of these integers for st6c, st8c, st9c ,ac7c, ac8c, ac9c, ac10c, ac11c. In PowerWorld, Position A and B are 1 and 2, respectively, but in GE PSLF they are 1 and 0. NOTE: In PSLF, for ST8C and ST9C Position A = 0 and Position B = 1 and this was also corrected.
