Software Patches

Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Added script command CTGCreateStuckBreakerCTGs(filter, AllowDuplicates, PrefixName, IncludeCTGLabel, BranchFieldName, SuffixName, PrefixComment, BranchFieldComment, SuffixComment).
  • Auxiliary Files (SCRIPT and DATA Sections): Added script command CTGCreateExpandedBreakerCTGs.
  • Contingency Analysis Tool: Added option to create stuck breaker contingencies. This will process each contingency that has explicit breaker outages defined and create new contingencies by treating each breaker as stuck in turn. The new contingencies will be comprised of all existing elements, minus the stuck breaker outage, plus open actions for breakers that are identified to isolate the stuck breakers.
  • Contingency Analysis Tool: Added option to create expanded breaker contingencies. This will convert any "Open with Breakers" or "Close with Breakers" contingeny actions into Open actions on explicit breakers. This will permanently modify the contingency definitions.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): When updating a ContingencyElement using a DATA section instead of a SUBDATA section, all of the parameters that are specified as part of the action but not used uniquely to identify an element were not being updated. This has been fixed.
    • Case Information Displays: Fixed bug with Interface Element advanced filtering.
    • Fault Analysis: Modified the calculation of the internal voltage for a generator.
    • File Formats: When writing out sequence data to the PTI file format for versions 33 and greater, now write ouf end of section kesy for zero sequence fixed shunt data and zero sequence machine data.
    • GIC: Fixed bug with display of transformer GIC Model Type parameter.
    • Transient Stability: The option to show the logo in the Title Block of a plot was being read in the opposite of how it was saved in a PWB file. This has been fixed.
    • Transient Stability: The Tripped Gen and Tripped Load values shown with contingency summary information could not be loaded from AUX files. This meant that this information was not available when using Distributed Computing for transient analysis. This has been fixed.
