Features and Improvements

  • Case Information Displays: Added new Interruptible field for loads. This is an information only field.
  • Case Information Displays: Added a new generator field "UnitTypeCode" that shows the two character code for the UnitType. The field is the same as UnitType, just shorter.
  • Oneline Diagrams: Added new dialog to show Objects Not on Oneline. This will display data objects that are not currently represented on the oneline. There is also an option to show objects that are NOT on the oneline that are connected to buses that ARE on the oneline.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): LimitA, B, and C are no longer required fields for an interface definition.
    • Auxiliary Files (SCRIPT and DATA Sections): Modified how CalculateTLRMultipleElement script command behaves when one of the branch is presently out of service or in a dead island. Previously it would cause the script command to return an error. Now it just returns zeros for all those values instead.
    • Case Information Displays: Model Expressions that link to many other model expressions can cause the display of case information displays for objects that use model expressions to be very slow. This includes Model Conditions, Model Filters, and Remedial Actions. This problem has been fixed.
    • Case Information Displays: The concise field for an interface called LimitMWA was not being shown properly and was showing LimitMWA:0. This has been fixed.
    • Case Information Displays: In Version 18 the voltage regfactor sharing parameter at each generator at a single bus was synchronized to be the same. In Version 19, the RegFactors can be different at each generator at a single bus. Modified the treatment of editing the generator RegFactor field so that when changing the value it does not automatically change the value at other generators at the same bus.
    • Case Information Displays: Added fields for three-winding transformers to edit the R, X, Gmag, Bmag values on the 3-winding transformer winding voltage bases and winding MVA bases.
    • Case Information Displays: Added support for editing the FixedTaps, Nominal voltages, and winding MVA Bases for 3-winding transformers and automatically pushing those changes to the 2-winding equivalent branches.
    • Case Information Displays: Modified transformer Branch records so that many fields associated with transformers can not be edited for the 2-winding equivalent branches of 3-winding transformers. This includes fields like the FixedTap or Nominal voltage at the internal star bus.
    • Distributed Computation: Fixed the issue with distributed contingency analysis taking forever to complete after a large run with lots of remote processes.
    • Distributed Computation: Fixed the issue with performing distributed runs from SimAuto.
    • File Formats: Cleaned up reading reading of 3-winding transformers records in an EPC file if the variable tap and the fixed tap on the primary winding were both not 1.0.
    • File Formats: When reading hdbexport files set load AGC flag based on BASEW comparison of LD record. If BASEW >= 0.5*W, set AGC false. In other words, if the base load is more than half the load value, it is turned off AGC.
    • User Interface Dialogs: When editing a generator and changing the remote regulation factor, Simulator was automatically setting all generators at the same bus to have the same remote regulation factor. This was required in Version 18 of Simulator, but in Version 19 we no longer require this, so this action on the dialog needed to be removed.
