Each bus is associated with an Owner record. These fields show the number and name of the owner.
See Owner Records Display for more information about Owners.
Voltage (per unit)
Bus voltage in per unit notation. You may enter a new per unit voltage magnitude. However, the
only effect this has is changing the initial voltage guess used in the iterative solution. If you would
like to change the reference voltage for a generator, please see Generator Information Dialog.
Voltage (kV)
Bus voltage in actual kilovolts.
Angle (deg) and Angle (rad)
Voltage angle at the bus in degrees and radians. You may enter a new voltage angle. However, the
only effect this has is changing the initial voltage guess used in the iterative solution EXCEPT AT THE
SLACK BUS. Changing the angle for the slack bus will shift the voltage angle for all the buses in the
slack bus' island by a similar amount.
Status
Status of the bus, either connected or disconnected. A disconnected bus is not energized. You can
use this field to change the status of the bus. When the bus is initially connected, selecting
Disconnected opens all of the transmission lines incident to the bus, disconnecting the bus from
the rest of the system. Selecting Connected closes all of the lines incident to the bus unless they
attach to another disconnected bus.
View Substation Dialog
Clicking on this button will open the substation dialog for the substation the bus is contained in.
View Owner Dialog
Clicking on this button will open the bus’ owner dialog.
Slack Bus
Checked only if the bus is a system slack bus. This value can only be changed in the Edit Mode.
View All Flows at Bus
Clicking on this button will open a quick power flow list for the current bus.
Generator Information
©2011 PowerWorld Corporation
Device Info
Displays the total MW and Mvar generation at the bus. You cannot change either of these fields from
this display. Select View/Edit Generator Records to view the individual generator records for the
bus. Selecting this button displays the Generator Dialog for the first generator at the bus.
Load Information
Displays the total MW and Mvar load at the bus. You cannot change either of these fields from this
display. Select View/Edit Bus Load Records to view the individual load records for the bus.
Selecting this button displays the Load Dialog.
Shunt Admittance
Shows the real and reactive components of the shunt admittance to ground. Entered in either MW or
Mvar, assuming one per unit voltage. B is positive for a capacitor and negative for a reactor. If B
corresponds to a switched device, consider using a switched shunt.
