Multi-section Line Display Objects
Multi-section lines are represented on the onelines using a line segment with intermediate or "dummy"
bus representations. These objects are not the same as a normal transmission line. They do display
animated flows in run mode, but do not have pie charts, circuit breakers, or text fields currently
associated with the objects.
Run Mode
Simulator's animation feature can be used to indicate the magnitude of the flow on the transmission
line, either in MW or in terms of the line's percentage loading. You can customize the line flow
animation using the Animated Flows Options on the Oneline Display Options Dialog.
Right-clicking on a multi-section line displays the Multi-section Line Information Dialog.
Edit Mode
Unlike transmission lines and transformers, multi-section lines CANNOT be inserted in a case by
adding the mult-section line graphically. Therefore, when inserting a multi-section line object, the
data for the object must already exist in the case. A list of currently defined multi-section lines is
found in the model explorer under Aggregations > Multi-Section Lines. Right-clicking and
selecting Insert… in the table that opens will allow you to add new multi-section line information
via the Multi-Section Line Information dialog.
To insert the multi-section line object, first select Network > MS Transmission Line from the
Individual Insert ribbon group on the Draw ribbon tab. Then place the cursor on the first bus for the
transmission line (the "from" bus) and click the left mouse button. Add more segments to the line by
moving the cursor and clicking with the left mouse button. To complete adding a new line, place the
cursor on the second bus for the line (the "to" bus) and double-click with the left mouse button.
Completing the multi-section line opens the Multi-section Line Information dialog. At the bottom of
this dialog are display options for the line, such as line pixel thickness, symbol size (for the series
capacitor representations, if any,) anchored, and options for drawing the buses.
To change the shape of the line, first left-click on the line to select it. This causes handles to appear
at each vertex. You can then move any vertex clicking and holding the left mouse button down on
the vertex, dragging it to a new location, and then releasing the mouse button. To remove a vertex,
hold down the CTRL key and then click the vertex you would like to delete. To add a vertex, hold
down the CTRL key and then click on the line where you would like to add a vertex.
