Features and Improvements
- Case Information Displays: Added fields for displaying Near Bus, Far Bus and Element ID for interface elements.
- Contingency Analysis Tool: Added new field with branches, "Contingency ResultsMax % Ld Loading Direction", that shows the direction of flow for the branch at the maximum loading level under all contingencies for which this branch is a violation.
- Sensitivity Calculations: For TLR calculations, determine the island in which the calculations occur based on the island of the TLR element. If the element's terminals are in different islands, no calculation is done. When doing the calculations, only the buses in the transactor object that are in the same island as the TLR element will be used. Previously, we would not do the calculation and notify the user that the transactor spanned multiple islands. When doing the weighted calculations for areas and injection groups, we also only include the buses that are in the same island as the TLR element.
- Transient Stability: Added reading of the AMETA record from a DYD file to indicate storage of angle information to transient stability results.
- Transient Stability: Added ability to read DYD file containing devices identified by label.
- Auxiliary Files (SCRIPT and DATA Sections): Fixed bugs created by loading unlinked bus participation points from an auxiliary file.
- Contingency Analysis: Fixed bug with linear DC contingency analysis if a contingency causes the system slack to be islanded. The results would show very high flows and overloads on branches that are in the island when they should really be zero.
- File Formats: Fixed a bug reading the UCTE files where blank lines in the description comments at the beginning of the file caused an access violation.
- General: When creating a new branch that connects to a dummy bus of an existing multi-section line, remove the multi-section line record. If attempting to create a multi-section line through an auxiliary file and at least one dummy bus connects to other buses than the terminals of the MSline or other dummy buses, do not allow the multi-section line to be created. Messages are written to the log indicating MSLines are being removed or not created.
- Transient Stability: Fixed bug with Modal Analysis input grid.
