Features and Improvements
- Case Information Displays: Branch Case Information Displays can now show the zero sequence values
- Contingency Analysis Tool: If the Post Solution Auxiliary file for contingency analysis is missing this is now treated as a fatal error and contingency analysis cannot run until this is problem is fixed.
- Transient Stability: Modified the VHVDC_A1 model, added several new allowed data inputs. Also updated the help documentation to describe this.
1. Added support for having Ldc = 0.
2. Modified so that if after trying Cdc = 0 to reduce the frequency of oscillation, if the frequency is still too high, then Ldc will be set to 0.0.
3. Allowsetting of Rdc = 0 AND Ldc = 0 to model a power conversion without the line circuit.
4. Modified so KIdc2CH <= 1. If it is larger than 1 it will be treated as equal to 1. - Auxiliary Files (SCRIPT and DATA Sections): Modified TapTransmissionLine to not cause an AUX file to abort if the branch does not exist.
- Contingency Analysis: When using script commands that save contingency options to an auxiliary file, options can be saved in CTG_Options_Value and CTG_Options data sections. The SolutionOptions field has been removed with CTG_Options so that the contingency specific solution options are not saved in both locations.
- Transient Stability: When plotting results after completion of a run and individually with the button in the plot designer would've resulted in a Plot series header with a comma and that was causing problems with saving a csv file. Now it will always use an "_" in plot series title/name.
- User Interface Dialogs: Impedance Calculator dialog changes. Cleaned up the dialog field population so that they wouldn't display NaN when a divide by zero came up. Captured instances of rpu/xpu = 0, bpu/gpu=0, rohm/gohm = 0, and gmho/bmho = 0 so that divide by zero would be avoided.
