This dialog is used to view information about each bus in the system. It can be displayed by right-clicking on any bus on the oneline and choosing Bus Information Dialog or choosing Show Dialog from the Bus Display. This dialog can only be reached in Run Mode, but has a similar Edit Mode counterpart. The Bus Information Dialog has the following fields:
Bus Number
Find By Number
To find a bus by its number, enter the number into the Bus Number field and then click this button.
Bus Name
Unique alphabetic identifier for the bus. You can use the small arrow immediately to the right of the bus name to view a list of all bus names in the case with valid display filters.
Find By Name
To find a bus by its name, enter the bus name into the Bus Name field (case insensitive) and then click this button.
Find…
If you do not know the exact bus number or name you are looking for, you can click this button to open the advanced search engine.
Nom. Voltage
Nominal voltage of the bus.
Labels
Clicking on this button will open the Label Manager dialog listing all of the labels assigned for the selected bus.
Area Number, Name
Each bus is associated with an Area record. These fields show the number and name of this area. See Area Records Display for more details about areas.
Zone Number, Name
Each bus is associated with a Zone record. These fields show the number and name of the zone. See Zone Records Display for more details about zones. You can also use the Zone Dialog to list the buses in a particular zone and to easily move a group of buses from one zone to another.
Substation Number, Name
Owner Number, Name
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.
Device Info
Generator Information
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.
Bus Voltage Regulation
This section lists the devices (if any) that are controlling the voltage at the bus. Select Bus Voltage Regulator Devices to view the individual devices regulating the voltage for the bus. Selecting this button displays the Bus Voltage Regulating Devices Dialog.
Desired PU Voltage
If the bus is being regulated by one or more devices, this field will display the desired regulated voltage (in per unit) the devices are attempting to maintain.
Fault Analysis Load Parameters
This page of the display is only available for buses which have one or more load attached to the bus. The parameters on this tab are used when running a fault analysis study. The values represent the total load at the bus for the negative and zero sequence as equivalent admittances. By default, these values are zero. For load buses, these values can be changed by the user, or they can be specified by loading short circuit data from within the Fault Analysis Dialog. It is also possible to define these values as non-zero at a bus where no load exists in the load flow, but it is not usually desirable to do so.
OPF
This tab is only available if you have the Optimal Power Flow (OPF) add-on tool for PowerWorld Simulator. This tab displays the MW marginal cost (Locational Marginal Price) for the bus when performing an OPF solution. The page also breaks down the LMP into its cost components.
Geography
The Geography page of the dialog provides information on the geographic location of the bus on the currently active oneline diagram. Also it provides a conversion tool between Lat/Lon and UTM Coordinates.
Custom
The Custom page of the dialog contains two sections: custom fields and memo.
The custom fields section allows access to setting and changing the values for custom fields that have been defined for the bus. Defining custom fields is detailed in Custom Field Descriptions.
The Memo section of the dialog is simply a location to log information about the bus. Any information entered in the memo box will be stored with the case when the case is saved to a PWB file.
