Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Added a new script command: TSResultStorageSetAll(objecttype, YES/NO). The first parameter is the objecttype such as GEN, BUS, BRANCH, etc. You may also use ALL to signify to do this for all classes. The second parameter is a YES or a NO. Using this command will toggle all the “Save All” fields to YES/NO. It will also toggle all the “state” fields (such as exciter, machine, governor, etc.) to YES/NO.
  • Case Information Displays: The GE Ohmic Data Flag field for branches can now be viewed in branch case information displays.
  • File Formats: When writing out an EPC file and the GE Ohmic Data Flag field is 1, R and X will be written in ohms and B in microMhos.
  • User Interface Dialogs: Quick Filters can now be used on dialogs when choosing objects.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): Fixed some errors with the SendToExcel script command if the workbook that is being written to is open when the script command is executed.
    • Contingency Analysis: Fixed a bug where the Post-Contingency Auxiliary File name would be blanked out if the file could not be found when specified from an auxiliary file.
    • Contingency Analysis: Corrected a problem that would not allow a relative path to be specified when providing the location of the Post-Contingency Auxiliary File.
    • Power Flow Solution: The SVSMO2 SVC model will now only move during the power flow solution if its regulated value is outside its high/low range. Previously, it was being adjusted to hit the target voltage which was causing oscillations in the solution.
    • Transient Stability: PIDGOV was not propertly using the MWCap (MVABase) associated with the model. This has been fixed.
    • Transient Stability: Fixed error with enforcement of non-windup limits with HYGOVR models.
    • Transient Stability: Ensure that log messages are written to show that something is actually occurring when using script commands to run transient stability.
    • Transient Stability: Ensure user cannot interrupt transient stability run started from a script command.
    • Transient Stability: Fixed treatment of damping in MOTOR1 model.
