This dialog is used to view/modify information about each bus in the system during Edit Mode. It is very similar in content to its Run Mode counterpart.
Bus Number
Unique number between 1 and 2,147,483,647 (equals 2^31 minus 1) used to identify the bus. You can use the spin button immediately to the right of the number to move to the next bus (click the up arrow) or the previous bus (click the down arrow).
If adding a new bus to the one-line display, this dialog will open after selecting the location of the bus display object. This dialog can be used to add a bus to the one-line for buses that already exist in the power flow case or new buses that should be created. If entering the bus number of a bus that does not already exist in the case, an informational message will appear above the Bus Number field indicating that using this bus number will insert a new bus into the power system data model and not just to the one-line display.
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.
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.
Nominal Voltage
Nominal voltage of the bus in kV.
Labels
Clicking on this button will open the Label Manager Dialog listing all of the labels assigned for the selected bus.
Area Number
Number of the bus’ area. Each bus must be associated with an area record. If a bus is specified as belonging to an area that does not already exist in the model, the new area is created.
Area Name
Alphabetic identifier for the bus’ area. If the area already exists, you do not need to enter this value.
Zone Number
Zone Name
Alphabetic identifier for the bus’ zone. If the zone already exists, you do not need to enter this value.
Owner Number
The number of the bus’ owner.
Owner Name
The name of the bus’ owner.
Substation Number
The number of the substation the bus is contained in. This is typically blank in most power flow data, unless specifically added to a PowerWorld binary save file.
Substation Name
The name of the substation the bus is contained in. This is typically blank in most power flow data, unless specifically added to a PowerWorld binary save file.
OK, Save, and Cancel
OK saves your changes and closes the dialog. Save saves your changes but does not close the dialog; this allows you to use, for example, the Find By Number command to edit additional buses. Cancel closes the dialog without saving any changes.
Bus Information
Voltage (pu), Angle (degrees)
Current per-unit voltage magnitude and angle for the bus. If you are inserting a new bus into an existing system, you should not change the initial per unit voltage values. Rather, when you first switch to Run Mode, Simulator will estimate the voltage magnitude and angle at the new buses in such a way as to reduce the initial mismatches. This automatic estimation is only available if you have not modified the voltage in any way. 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.
System Slack Bus
Display
Orientation
Set the orientation of the bus. The current choices are right, left, up or down. For the current bus object shapes of Rectangle and Ellipse, right and left are analogous to horizontal, up and down are analogous to vertical. Additional shapes for buses may be available in the future for which right, left, up and down may have more specific impact on the appearance of the bus object.
Shape
Sets the shape of the bus object.
Width
Specifies the horizontal axis of an elliptical bus or horizontal side length of a rectangular bus.
Size
Specifies the vertical axis of an elliptical bus or the vertical side length of a rectangular bus.
Scale Width with Size
When this option is checked, changing the size will cause the width to automatically adjust to keep the same ratio of width to size. To adjust the width independent of the size, uncheck this option or adjust the width separately after adjusting the size.
Link to New Bus
If you have right clicked on a bus and opened the bus information dialog, you could change the bus number in the Bus Number field and press this button to force the bus object on the diagram to link to the new bus number and information in the load flow data.
Attached Devices
Load Summary Information
Displays the net MW and Mvar load at the bus. You cannot change either of these fields from this display. Select the Add or Edit Bus Load Records to view the individual load records for the bus via the Load Dialog.
Shunt Admittance
The real (G) and reactive (B) components of shunt compensation at the bus, expressed in MW and MVR, respectively.
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.
Fault Parameters
This tab is only visible when viewing the bus information for a bus with attached load. 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.
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.
