Features and Improvements
- Auxiliary Files (SCRIPT and DATA Sections): When using the MergeLineTerminals() script command, we now send a message to the log if no lines are actually selected for merging.
- QV Curves: When exporting QV results to a CSV file, all results are now sorted by the voltage setpoint.
- Transient Stability: When loading in synchronous machine saturation values specified at 1.0 and 1.2 per unit, if S(1.2) < S(1.0) then Simulator will flip the values to autocorrect.
- File Formats: When writing out the internal generator R and X values to a RAW file, an old limitation existed preventing values larger than 999. This limitation has been removed.
- File Formats: When loading text files, modified to treat TAB characters identically to SPACE characters.
- File Formats: When appending to a case (from an EPC, RAW, or PWB file) if the From and To designations of a branch are backwards in the appending file, then the designations will now be flipped as part of the appending processes.
- Oneline Diagrams: Changed the icon size for the end of transmission lines to be smaller when exporting to a KML file.
- Power Flow Solution: When calculating the flow on a branch after solving a DC power flow, the contribution of MW Line Shunts was not properly handled. The actually DC power flow solution was correct, but the line flow would not be correct. This has been fixed.
- Sensitivity Calculations: Fixed bug in the LODF calculations introduced in the July 23 patch.
- Time Step Simulation: Fixed bug with writing out injection group CSV files that would add the date and time to the file twice. This would also have affected the switched shunt CSV files.
- Time Step Simulation: Added scroll box around options on the Time Step Simulation dialog.
- Transient Stability: Fixed a bug where trying to show a plot at the execution of transient stability. The plots were shown but never properly refreshed.
- Transient Stability: Modified so that the generator internal R and X values are always updated to match the generator subtransient or transient impedances as appropriate. This is done when the stability is either solved or when the stability data is loaded or stored. These fields must match and the stability data exported to other software must reflect the fact that Simulator always uses the data specified with machine models.
- Transient Stability: Fixed a bug in how the saturation of GENROU and GENSAE models was handled.
