Features and Improvements

  • File Formats: When writing out to EPC files, save to version 18 by default.
  • File Formats: The extra GE EPC fields are now always available with case information displays. The option for the user to specify this has been removed.
  • File Formats: When reading a RAW file, comments for transformer records will now be added to the transformer Memo field.
  • General: Allow the pre-filter option using Area/Zone/Owner filters to be used with Quick Filters.
  • Bug Fixes

    • Contingency Analysis: When running contingency analysis, using a post-contingency auxiliary file, and using Integrated Topology Processing, access violations could result during or following contingency analysis. This has been fixed.
    • Distributed Computation: Fixed a problem with the master instance of distributed contingency analysis where it wouldn't handle errors in remote machines properly, causing Simulator to instantly crash and disappear.
    • Distributed Computation: Reduced memory usage required in distributed contingency analysis by incrementally processing results.
    • File Formats: When appending EPC files that convert switched shunts to fixed shunts or vice versa and an existing shunt is first marked to be deleted and is then replaced with a new shunt, make sure that the Flagged for Delete field is set correctly.
    • File Formats: When saving to EPC version 18 with a switched shunt that was originally identified as SVD type 5, 6, or 7, write out the original befmin and befmax stored with the GE extra data instead of the min and max Mvar of the switched shunt itself.
    • Integrated Topology Processing (ITP): When running contingency analysis, using a post-contingency auxiliary file, and using Integrated Topology Processing, access violations could result during or following contingency analysis. This has been fixed.
    • Oneline Diagrams: When displaying fields on a oneline in italics, some of the text could be clipped. This has been fixed.
    • Oneline Diagrams: Using the substation renumbering tool was breaking the links between the oneline substation objects and data objects. This has been fixed.
