Simulator 16 User Guide - PowerWorld

control and is required to meet the regulated voltage. This option is applied any time that
the power flow is solved.
When using the Economic Merit Order Dispatch method with the PV tool and a generator is
needed in the dispatch, breakers will be closed automatically to energize the generator if
necessary.
Added script command CloseWithBreakers.
Oneline Diagrams
When using a contour with a dynamic interpretation, if all the values being contoured had
the same value the contour image could appear random. This was remedied by enforcing a
minimum tolerance on the separation between minimum, nominal, and maximum values of
the color map.
Added a Simulator Oneline option that alter how Simulator responds when click on a circuit
breaker symbol for a generator display object. Normally the generator's status is set to
closed and the MW value is reset to its previous value. The new option allows the value to
be set to its minimum MW output instead.
When changing to a Saved View which specifies that a contour be shown, we now
automatically refresh the contour image
Added ability to export a oneline diagram as a GIF image.
Added ability to export a oneline diagram as an animated GIF image (animated the arrows
and generator rotors).
When opening a oneline diagram using the AXD format, if no Saved View named
THIS_VIEW_IS_APPLIED_TO_THE_CURRENT_DISPLAY is specified, then a Show Full will
automatically occur for the oneline.
When clicking on a oneline diagram, substation oneline objects have been modified to give
preference for clicking on the substation. If another object overlaps the substation,
Simulator will still register the click on the substation now.
For dynamic formatting purposes, Model Fields will behave like the type of field that they
are showing. Thus, a model field showing Area information will behave as though it is an
Area Field.
Modified Line Flow Arrow objects so that the text better aligns with the arrow.
Added a new Interface Flow Arrow Object which behaves very similar to the Line Flow
Object show an arrow to represent the MW flow direction and then shown text for MW
value and Mvar value with a sign relative to the MW flow direction.
Previously an option existed in Simulator which allowed you to specify whether to show
transformer symbols using either Coil or Circles. We now also have a oneline-specific option
which allows this option to be different for different onelines.
Added options to automatically load a Display Auxiliary File (AXD) with each oneline that is
opened. One option stores the settings in the windows registry so this applies to all onelines
opened on the computer. Another option stores the settings in the case (PWB) so that it
only applies to onelines opened with the specific case.
Added an option stored with the case to specify the maximum number of onelines that can
be open simultaneously (this option defaults to 10). If this maximum threshold is exceeded,
Simulator will automatically close the oneline whose most recent access is 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 has been added for users
who make extensive use of oneline links or substations display object links which can make
opening dozens of onelines very easy. Opening dozens of onelines can slow down the
program substantially. If you have a main oneline from which other onelines are
automatically opened, you may want to prevent the main oneline from closing.
Added transparency with contouring. Transparency can be defined with either the No Data
Color or with a custom color map.
