Simulator 16 User Guide - PowerWorld

then typing in the new value. Other values are toggleable and can be changed by double-clicking on
the value. For reference regarding what the various "size" defaults mean, when the zoom level is at
its nominal value (100%), the size of the screen is 100 by 100. There are also some special kinds of
fields in this dialog which are discussed next.
Editing Colors and KV-Based Color Coding
In order to modify a color value, double-click on the colored rectangle to bring up the Color Dialog.
Then specify the color you want. For some defaults, such as fill color, it is possible to specify the
default color to be none. In order to set a color default to none, select the colored rectangle and
press the Delete key.
At times, a user may want to see the kV level of screen objects directly from the oneline diagam,
without having to open a text display. One way to do this is to color code the elements on the
oneline diagram according to kV level. Right-click on the table and choose Insert from the local
menu. Specify the Nom kV and color.
Editing Default Field Positions ("Pos1", "Pos2", etc…)
Many objects allow you to specify some default fields to be automatically added when a new object
is drawn. For example, you may want to insert the bus name next to all new Bus Objects. For
objects that allow the insertion of fields, a tab with field position diagrams will be available when
that object type is selected. In order to specify the default positions of fields, click on the tab
showing the field positions and click on the table row corresponding to the Nom kV of the defaults of
interest. For object types that do not allow specifying the defaults by Nom kV, simply update the
given position diagram. The position diagram will show the present settings for the new fields.
Positions that have a default specified will be highlighted and the name of the default field will be
shown. Positions with no default field will not be highlighted and will say "Pos1", "Pos2", etc…. For
objects that have more than one possible orientation (e.g. generators can be up, right, left or
down), there are multiple position diagrams showing the positions for each orientation.
In order to modify the settings, move your mouse over the position on the dialog you want to
change and click. This will bring up the appropriate Field Options Dialog such as the Bus Field
Options, Generator Field Options, Load Field Options, Switched Shunt Field Options, Line Field
Options, Interface Field Options, Substation Field Options, Area Field Options, Super Area Field
Options, or the Zone Field Options. Simply select the field you want and choose OK. If you would
like to set a default field to "none", click Remove Field instead of OK. You can also modify default
fields by double-clicking on the table for "Pos1", "Pos2", etc… This brings up the appropriate Field
Options Dialog as well. If you press the Delete key while on a "Pos" field in the table, it will set the
default field to "none".
Editing Stub Size and Stub Space
When utilizing the Automatically Insert Transmission Lines feature, the Stub Size and Stub Space
values are used. Simulator will draw each automatically inserted branch such that it emerges from
both its terminal buses at right angles. To accomplish this, Simulator draws each automatically
inserted branch in three segments: two stubs perpendicular to the terminal buses having a length
specified by the value supplied for Stub Size, and a third segment joining the two stubs. The
amount of space between lines as they converge into a bus is set by Stub Space.
If you do not want transmission line stubs to be inserted, then set Stub Size to none or to a
negative number. Note in order to set a value for Stub Space, Stub Size must be set to a positive
number first.
Editing CB Size
When you insert new transmission lines or transformers, circuit breakers will automatically be
inserted on the branch with their size specified by CB Size. If you do not want Circuit Breakers
inserted for a particular voltage level, then set CB Size to none or a negative number.
