Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Updated DiffFlowWriteRemovedEPC script command. Now allows GEFileType: DiffFlowWriteRemovedEPC("filename", GETypeFile);
  • Power Flow Solution: added Switched Shunt field for "AutoControl" which may be specified as either YES or NO to specify whether the shunt is allowed to be automatically controlled. This means that you no longer are required to set the Control Mode to FIXED to indicate that it can't be controlled.
  • Transient Stability: Modified so that when showing the Transient Limit Monitor Dialog we automatically show the Limit Duration in Cycles if it is with 0.02 cycles of being at an integer multiple of a cycle up to 60 cycles. Thus at 1, 2, 3, 4, ... 59, and 60 cycles. Also modified so that if we're within 0.02 cycles of being at 0.5, 1.5 and 2.5 cycles the dialog will show the Limit Duration in cycles. Otherwise, it will automatically show the dialog in seconds instead. Internally within Simulator, we store this value as a floating point number of seconds, but this makes it convenient for viewing on the dialog.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): fixed bug with entering DCLine EPC-related fields if an EPC file hadn't been read to start.
    • Auxiliary Files (SCRIPT and DATA Sections): Fixed error with creating a switched shunt that was an SVC of type SVSMO1 or SVSMO3. The shunt wasn't being properly initialized for solution when created using an AUX file.
    • Auxiliary Files (SCRIPT and DATA Sections): When creating a continuous switched shunt from an AUX file, we must initialize whether the shunt is at a high or low limit so that the initial guess regarding a PV or PQ bus in the power flow solution is consistent with the initial shunt's state.
    • General: Fixing a bug that caused SimAuto to not function propertly when using hardware keys.
    • GIC: added ability to save and load new options regarding hot spot simulation from GIC_options to an AUX file.
    • GIC: modified to be able to see additional fields for the GICXFormer object. The GIC Model Used Break Point and GIC Model Used Second Segment.
    • GIC: modified to gray out the text for the 3 GIC Model input parameters if the GIC Model Type is set to Default to make it clear those values aren't being used.
