Features and Improvements
- Auxiliary Files (SCRIPT and DATA Sections): Made a fix so that OPENNETEMS file types can be loaded using the OpenCase script command.
- File Formats: A fix was made in the March 28, 2019 patch if a case has transient stability line relay models assigned to the entire system. An access violation could occur on loading the PWB file. The fix made to the March 28, 2019 patch resulted in not being able to open a file saved in the March 28 patch in previous patches. The fix in this current patch will allow files saved in this patch and later to be opened in all previous patches. Patches between March 28 and the current patch will have an error on load if they contain line relay models assigned to the entire system and they are opened in patches prior to March 28.
- Power Flow Solution: It was possible for the power flow to fail if a bus contained multiple generators that did not all have the same regulated bus specified. This failure could occur even if generators with conflicting regulated buses were not set to be on AVR control. This has been fixed.
- Transient Stability: When using the Open Injection Group transient contingency action to open a certain amount of load, you may now call open on the injection group repeatedly and have it continue opening additional loads.
