Features and Improvements
- PV and QV Curve (PVQV) Tool: @CASENAME, @CTGNAME, and @CTGMEMO will now work as special keywords in the title block for PV plots in a similar manner to the Transient Stability Plots.
- Transient Stability: Adding a new global transient stability option for "Minimum Voltage For Frequency Relay". When the per unit voltage is below this threshold then all frequency relays will treat their measured frequency as nominal frequency. This was done to mimic the voltage inhibit flag of real relay models and also to prevent motors stuck behind a fault from tripping on low frequency when the measured frequency behind the fault is suspect.
- User Interface Dialogs: On various dialogs that have a custom tab (Bus, Gen, Shunt, Branch, etc...) which shows the custom fields, the assignment of the DataMaintainer may now be done on the Custom tab
- User Interface Dialogs: Modified the Switched Shunt dialogs to be sizable to make editing their transient stability models easier.
- Auxiliary Files (SCRIPT and DATA Sections): Fixed bug that would not allow using the special busloc ALL to return all available fields with a particular variablename.
- File Formats: When writing out shunt data to an EPC file, we had been writing -1 for the bus number of the controlling shunt when there was no controlling shunt. Now we are writing 0.
- File Formats: Added svc important fields needed when saving case as an entire case to an aux file.
- Transient Stability: Adding in support for transformer tap switching in the distribution equivalent model and in the CMPLDW model. Previously this was being ignored.
- Transient Stability: When showing plots, the legend text was always appearing as black instead of the same color as the plot series to which it refers. The font color will now again be based on the plot series to which it refers.
- Transient Stability: For load object fields shown in the plot designer field list, the "Relay" and "Feeder" Other fields were flipped in the user interface. The folders for the feeder fields would say "relay" and vice versa. This was a cosmetic error and is fixed.
