Bus View Display
The Bus View Display feature provides a graphical display which allows you to quickly browse
information about a bus and everything connect to that bus. The bus view displays enable convenient
bus-by-bus navigation through the power system. From the bus view, you can find out a bus’ voltage
and angle, the load, shunt compensation, and generation connected to the bus, and the flows on all
lines emanating from the bus. You can also discover the bus’ area and zone affiliations, as well as the
bus’ marginal cost. Moreover you can find out all information about the elements associated with the
bus by directly invoking their associated information dialogs. The advantage of the bus view displays,
is that they are auto-created oneline diagrams.
Along the top of the bus view display resides a panel of controls. The buttons labeled Back and
Ahead allow you to step through the history of buses you have viewed thus far. To move the bus
view to a particular bus, type a number or name into the edit box next to the caption Bus. If a
number is typed the case will be scanned for a bus of that number, otherwise the case will be scanned
for a bus that starts with the string entered. If you’re unsure which bus that you are looking for click
the Find… button to bring up a display that allows you to search using wildcard strings for the bus.
The History menu will show a list of the last 30 buses which have been visited in a bus view. There
are also drop-downs in this top panel for Options and Views . These are discussed below.
Below this top panel sits the actual bus display. The bus you have chosen to inspect, which we shall
refer to as the target bus, is represented by a long, thick horizontal line. Notice that the bus’ voltage in
kV and per unit, its angle, and its marginal cost are specified to the left of the bus. Any loads and
generating loads connected to the target bus are drawn above the bus symbol, along with their
associated annotation. Also any radial connections to a single bus containing load, generator or
switched shunts will be drawn above the bus symbol.
Emanating from the bottom of the bus symbol are all transmission lines and transformers that connect
the target bus to its neighbors. The transmission line and transformer symbols are equipped with pie
charts and annotation identifying flows as measured at the target bus, as well as arrows to identify the
direction of MW flow on the branch. Neighboring buses are represented as filled rectangular regions,
with symbol indicators included if other types of devices, such as loads, generators, etc., are attached.
When you drag the mouse over one of the neighboring bus symbols, it turns into a pointing finger.
Clicking the left mouse button when the mouse cursor is in this shape redefines the target bus to be
the bus whose symbol you just clicked. The bus view display is redrawn to show the same sort of
display for the newly chosen target. You can go back to the previously displayed target bus by clicking
the Back arrow, and then return to this record by clicking the Ahead arrow.
It is useful to think of the bus view displays as nothing more than an additional oneline diagram. In
other words, you interact with the objects drawn on the bus view display in the same way you work
with objects on a more conventional Simulator oneline. Right-clicking on any power system object will
bring up that object’s local menu, which includes a link to the object’s associated information dialog.
As on a conventional oneline diagram, flows on a bus view display can be animated. Right-clicking on
the bus view display’s background will generate the same local menu as other oneline diagrams.
The bus view display can be generated using any of the following methods:
Go to the Case Information ribbon tab, and click on the Bus View from the Views ribbon group
Go to the Onelines ribbon tab, and click on the Bus View from the Views ribbon group.
Right click on the bus of interest on the oneline diagram to display the bus’ local menu, and
choose Bus View. The bus view display will open with the selected bus already displayed.
