Multi-section Line Display Objects

See Also

 

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.

The Right -click option, Convert MS-lines into background lines... converts the MS Line display object into a background line. You can convert the background back to a MS-line by right clicking on the background line.

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 > MS Transmission 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.
