Advanced Filters Dialog
The first thing to choose on the Advanced Filter dialog is what to Filter By and the Filter Type.
Filter By
Filter By can be set to either Advanced or Device.
Advanced Filtering allows you to define a set of logical comparisons for the various fields which
must be met. For example you may want to only see Buses that meet the conditions "Nominal
Voltage > 100 kV" AND "MW Load > 100 MW". For more help on Advanced Filtering see the topic
Advanced Filtering: Advanced.
Device Filtering allows you to directly use one of the power system model objects as a filter. The
relationship between the object type being listed and the object type of the device filter determines
how filtering is done. For example, if you use an Injection Group as a device filter to filter a list of
Generators, then you will get only the generators which are inside the Injection Group. As another
example, if you are using an Injection Group as a device filter to filter a list of Branches, then you
will get only branches that are connected to the terminal bus of any generator, load, or switched
shunt contained in the injection group. Device filtering can be used instead of more complicated
Advanced Filters. For more help on Device Filtering see the topic Advanced Filter: Device.
Select Filter Type
When defining an Advanced Filter, normally this type is the same as the object type for which your
are defining a filter. When defining a Device Filter, normally this type will be different.
By changing the drop-down next to Select Filter Type, it is possible to filter based on data for a
related object instead of for the actual object. For example, an Advanced Filter for a Bus may exist
to only show buses with a Nominal Voltage larger than 138 kV. You may then want to use this filter
on a case information display which shows generators. This is possible by changing the Filter Type
to be a Bus when showing the Filter Dialog on the Generator case information display. Just click the
drop-down to see which related objects' filters can be used for that particular situation.
View Filter Logic
Select View Filter Logic to show a graphical display to visualize the logic diagram for an Advanced
Filter.
Note Regarding Auxiliary Files: Throughout auxiliary script commands, the ability to specify an
advanced filter by name is available. In this context, if the use of an Advanced Bus filter is desired in a
place where an Advanced Generator filter is needed, then use the string " filtername" to
