Simulator 16 User Guide - PowerWorld

Oneline Options
These options are available on the Oneline tab of the PowerWorld Simulator Options dialog. It is
important to note that the options on this dialog apply to all oneline diagrams. There are also a large
number of options which apply only to an individual oneline diagram. The diagram-specific options are
specified on the Oneline Display Options Dialog.
There are two sub-categories on the Oneline Options tab: Visualization and File.
Visualizing out-of-service elements

Visualization
These three options allow you to choose how objects on the diagram should appear when they are
representing a power system device that is currently "open" or "out-of-service." The three options
are Blink, Use dashed lines, and Draw and X through off-line generators. The first two options apply
to any oneline object, while the third option is specific to generator objects only.
Set gen MW to min when closed from oneline
This option allows the generator MW value to be set to its minimum MW output after a circuit
breaker is clicked in the oneline display. Normally the generator's status is set to closed and the MW
value is reset to its previous value.
Show Oneline Hints
If checked, pop-up hints will appear when you drag the mouse over an object in the oneline. These
give information about the object; for example, for a generator the pop-up hint displays the bus
number, generator ID, the MW output and the MVAR output. You may also customize the pop-up
hints for each kind of display object by choosing Options > Custom Hint Values from the menu.
Show X,Y Coordinates
If checked, the (x,y) location of the cursor is monitored in the status bar at the bottom of the
screen. The (x,y) location of the cursor is only shown in Edit Mode. By default, this option is
selected.
Save Contour Image with Oneline File
If checked, and if a contour is being displayed on the oneline diagram, Simulator will store the
contour with the oneline diagram when you save the case or save the oneline. It will store the
contour as a bitmap.
Display Unlinked Elements in Run Mode
Typically, unlinked graphical objects are not visible in Run Mode. Checking this option will allow the
display of unlinked elements during Run Mode.
Enable Mouse Wheel Zooming
This option allow the use of the mouse wheel to zoom in and out in the currently selected oneline
diagram.
Maximum number of open onelines
Option to specify the maximum number of onelines that can be open simultaneously (this option
defaults to 10). If this maximum threshold is exceeded than PowerWorld will automatically close the
oneline whose most recent access is the oldest. By default a oneline can be closed in this manner,
but an additional oneline-specific option has been added that can be changed to prevent this
closure. This feature is useful for users who make extensive use of oneline links or substation display
object links which can make opening dozens of onelines very easy. Opening dozens of onelines can
