Features and Improvements
- File Formats: When loading in an auxiliary file, read the switched shunt regulation type field before the regulation range values because the regulation type will determine the units of the regulation range.
- General: Added more circular reference checking for Model Conditions, Model Filters, and Model Expressions.
- Oneline Diagrams: Added option in Simulator Options under Onelines --> Files --> Open Oneline Links By to specify if oneline links are to be opened by Number, Name_kV, or Label.
- PV and QV Curve (PVQV) Tool: Model Conditions and Filters that are part of contingency model criteria used during PV and QV analysis now allow use of the Model Condition option to Disable if Condition is True in Contingency Reference State.
- Transient Stability: Added a Transient Contingency option to set the per-unit resistance and reactance of an AC line or transformer.
- Case Information Displays: The option to visualize the Model Filter logic has been moved from the local menu under Insert Filter Logic to Model Filter Records --> Visualize Filter Logic.
- Distributed Computation: Fixed "invalid variant type" errors that would occur during distributed ATC. This was caused by Simulator attempting to distribute setup information that doesn't exist, i.e. blank extra monitors or interface rating scenarios. Simulator no longer attempts to send this information.
- General: When visualizing Model Filter logic and a circular reference is found, a graphical indication of the circular reference will be presented instead of a logic diagram.
- Oneline Diagrams: The ability to scroll and zoom on a oneline diagram could be lost after a message dialog appeared. This has been fixed.
- Power Flow Solution: It was possible for a generator that was not initially on AVR control to get pegged at a Mvar limit and never be allowed to move from the limit if it was set on AVR control. This has been fixed. This fix is related to the fix that was made with the Jan. 25, 2012 patch also related to generators being set at Mvar limits.
- Time Step Simulation: Fixed a bug that would not apply custom input values for buses.
- Transient Stability: Corrected LCFB1_PTI input parameters.
- Transient Stability: Fixed bug with EXAC3 in which initial Va limits were being modified based on the value of Vr. Now we use Va.
- User Interface Dialogs: When using the chooser display available on many dialogs to pick an object, switching between identifying the object by Name, Number, or Label should now keep the same object selected regardless of how it is being identified.
