Automatically Inserting Transmission Lines
The Automatic Insertion of Lines/Transformers Dialog is used to automatically draw transmission lines
and transformers on the oneline diagram between existing bus display objects. Only branches that are
already defined in the power flow case can be added automatically; if you need to define a brand new
branch, see Transmission Line Display Objects. Thus, this option is useful only when you are starting
with an existing power flow case, not building a case from scratch.
To insert lines and transformers automatically, you must first have drawn the buses for each end of
the device. Simulator then draws the branch display objects connecting the buses for each
transmission line/transformer in the power flow case not already shown on the oneline.
To display the dialog, in the Edit Mode go to the Draw ribbon tab and choose Auto Insert > Lines on
the Quick Insert ribbon group.
The dialog has the following options:
Minimum kV Level
Simulator will automatically draw line and transformer display objects between terminals whose
nominal voltages meet or exceed the minimum kV level specified in this field. For a branch object to
be drawn, either one of its terminals must satisfy this criterion. This option is useful for suppressing
the automatic addition of generator step-up transformers if that kind of detail is not warranted.
Default Drawing Values
This button opens the Default Drawing Values Dialog. Options such as the automatic insertion of
transmission line stubs, text fields, circuit breakers, and pie charts are specified in the Default
Drawing Values Dialog.
Insert Text Fields
If this box is checked, the default fields associated with the transmission line will appear around the
transmission line.
Insert Equivalenced Objects
If this option is checked, equivalenced objects modeled as lines will also be automatically inserted
with the real transmission lines.
Use Only Selected Buses
Instead of having Simulator automatically insert line and transformer display objects throughout the
oneline diagram, you can force it to insert the new objects only between the bus display objects that
are currently selected. This option is enabled only when two or more bus display objects are
currently selected on the oneline.
Insert Pie Chart for Lines with No Limit and Bus Ties
If this option is checked, Simulator will add pie chart objects to the lines that have no given limit or
are bus ties as they are auto-inserted. Typically if a line is a bus tie or has no given limit, it is
meaningless to include a pie chart on the element, since no relevant information about the
transmission element can be gained from the pie chart object.
Insert Multi Section Lines
Check this option if you wish for Simulator to automatically insert lines designated as multi-section
lines as well.
