Features and Improvements
- Auxiliary Files (SCRIPT and DATA Sections): Added new DATA object, DefDrawOneline, that will allow changing the default font (name, size, color, and style), option to use the default font size for all new text fields, and the default background color for oneline diagrams via an auxiliary file.
- Case Information Displays: Allow advanced filtering on the Modify/Create Limit Groups table of the Limit Monitoring Settings and Violations dialog. This also affects the LimitSet data object when using scripts.
- Case Information Displays: Added transformer fields on the transformer base to the Difference Flows base case to that they can be properly compared.
- Power Flow Solution: Added VSC DC Line state to the system state that is used for restoring the last successful solution or state before a failed solution along with the contingency analysis, PVQV, ATC, and other reference states.
- Transient Stability: Added option to allow conversion of the composite load model (CMPLDW) to component parts for use in the power flow.
- Transient Stability: Added Alarm field to OEL1 model.
- Transient Stability: Added option to not flip machine saturation values when S12 < S1.
- User Interface Dialogs: Moved the option "Disable Transformer Tap Control if Tap Sens. is the Wrong Sign" from the Common Options to the Advanced Options tab of the Power Flow Solution options.
- Case Information Displays: Fixed a bug that would not allow a switched shunt to be created when pasting from Excel. The error indicated that all required fields were not present even though they were.
- Contingency Analysis: Fixed some bugs that would cause the Make-up Power grid on the Contingency Analysis dialog not to refresh correctly.
- Contingency Analysis: Fixed a bug that would change to the Results page on the Contingency Analysis dialog when making changes to other pages on the dialog.
- Contingency Analysis: Fixed a bug that would not show the entire description of What Actually Occurred on the Applied and Skipped Actions dialog.
- Distributed Computation: Fixed a bug that would cause authentication to fail when setting up the list of computers to use with Distributed Computing.
- Oneline Diagrams: Fixed a bug where the default oneline background color was not always updating properly.
- Optimal Power Flow (OPF): Fixed bug that would not show the OPF Options and Results dialog the first time that it is opened.
- Sensitivity Calculations: When calculating with Multiple Elements on the TLR Sensitivities form, the "Clear before Calculate" option is always set.
- Time Step Simulation: Fixed a bug that would produce an out of memory error when reading TSB files saved in version 15 or earlier of Simulator.
- Transient Stability: When loading in a GE DYD file, there is no longer the requirement that exciters be read before stabilizers.
- Transient Stability: Fixed reading in the GENCLS_PLAYBACK model from a GE DYD file.
- Transient Stability: Replace double quotes in the invocation section (identifier before the colon) of a GE DYD file with single quotes to handle bad file formats.
- Transient Stability: Corrected reading of the CMPLDW model so that the mvabase is read and stored.
- Transient Stability: Fixed writing IEEEG1_GE and ESST1A_GE to GE DYD file.
- Transient Stability: Modified handling of mechanical torque's speed dependence for MOTORW.
- Transient Stability: Fixed bug with EXAC8B correctly handling scaled Vrmin/Vrmax limits when Ta=0.
- Transient Stability: on ESAC7B set Vfemax to a minimum of 3 if it is greater than 0 and less than 3.
- Transient Stability: Added SMVABase parameter for CMPLDW.
- User Interface Dialogs: On the Branch Information dialog, show the impedances with 6 decimal places rather than 5. This fixes some potential issues when changing transformer base parameters.
