Software Patches

Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Added NewBusName parameter at end of TapTransmissionLine script command to specify the name of the new bus created at the tap point.
  • File Formats: When saving out an equivalent system to a RAW file, substations will not be saved.
  • File Formats: Modified read of correction table records. Now if we read a tap/scale pair of 0,0 we stop reading the rest of that record, and move on to the next one. Any points read up to the 0,0 will be kept and added to that correction table. Also modified that if the tap or scaling factor are not valid numbers, we also abort and keep only the valid points read up to the errant value.
  • Time Step Simulation: New PFW model for Gen MaxMW, WindGeneral, to model a user specified power-speed curve. A few other minor changes.
  • Bug Fixes

    • File Formats: When reading Areva CSV contingency records, when reading CTGL records which pointed to a TYPE.ID = SVS then invalid ContingencyElement objects were being created resulting in an access violation when running the contingency. This has been fixed so that we now support SVS actions.
    • Transient Stability: When using "Save Plot Images for Auto-Save Options" or as part of a transient stability run, a PDF of multiple contingency plots was not being saved. This bug has been fixed.
