Area field display objects are used to show different values associated with areas and the system on onelines.
This dialog can be opened by right-clicking on an area display field and choosing to open the Area Field Dialog while in run mode. If in edit mode this dialog will be opened simply by right-clicking on an area display field.
This dialog is used to view and modify the parameters associated with these fields.
Area Number
Area number associated with the field. When you insert fields graphically, this field is automatically set to the area number associated with the closest bus on the oneline. With most types of area fields, an area number of 0 is valid and defines the field as showing values for the entire system.
Find…
If you do not know the exact area you are looking for, you can click this button to open the advanced search engine.
Total Digits in Fields
Total number of digits to show in the field.
Digits to Right of Decimal
Number of digits to show to the right of the decimal point.
Rotation Angle in Degrees
The angle at which the text is to appear on the oneline diagram.
Other Area Number
Some of the fields, such as MW Flow to Other Area, require that a second area be specified. If applicable, enter the second (other) area here.
Other Area Transaction ID
Because it is possible to have more than one base transaction defined between the same two areas, base transactions must now also have a unique ID to distinguish between transactions among the same two areas. If you are displaying a field that pertains to the display of the scheduled flow between areas, the ID of the transaction in question will also need to be entered here.
Delta MW per Mouse Click
This value is used only with the Sched Flow to Other Area field type. When there is a nonzero entry in this field, and the field type is Sched Flow to Other Area, a spin button is shown to the right of the area field. When the up spin button is clicked, the flow to the other area is increased by this number of MW; when the down button is clicked, the scheduled flow is decreased by this amount.
Field Prefix
A prefix that can be specified and displayed with the selected value.
Field Value
Shows the current output for the area field. Whenever you change the Type of Field selection, this field is updated.
For the Sched Flow to Other Area field type only, you can specify a new value in MW. Exports are assumed to be positive.
Anchored
If checked, the area field will be anchored to a corresponding Area Object. If the area object is moved on the diagram, the text field will move with it.
Include Suffix
If this checkbox is checked, the corresponding field units will be displayed after the current value. Otherwise, only the value without units will be shown.
Type of Field
Used to determine the type of bus field to show. The following choices are available:
Name
Name of the area. Area Number must be non-zero for this field to be non-blank.
Number
Number of the area. Area Number must be non-zero for this field to be non-blank.
MW Load, Mvar Load
If the Area Number is non-zero, then these fields show Total MW or Mvar load for the area. If the area number is zero, these fields show the total load in the entire system.
MW Generation, Mvar Generation
If the Area Number is non-zero, then these fields show Total MW or Mvar generation for the area. If the area number is zero, these fields show the total generation in the entire system.
MW Losses, Mvar Losses
If the Area Number is non-zero, then these fields show Total MW or Mvar losses for the area. If the area number is zero, these fields show the total losses in the entire system.
ACE (MW)
Area Control Error in MW for the area. The Area Number field must correspond to a valid non-zero area.
Hourly Cost ($/hr)
If the Area Number is non-zero, then this field shows the hourly cost for the area. If the area number is zero, these fields show the hourly cost for the entire system.
Total Cost ($)
If the Area Number is non-zero, this field shows the total cost incurred by the area since the beginning of the simulation. If the area number is zero, this field shows the total cost incurred throughout the system since the beginning of the simulation.
MW Flow to Other Area,
Mvar Flow to Other Area
Total MW or Mvar flow from the area specified in the Area Number field to the area specified in the Other Area Number field. The area number field must correspond to a valid non-zero area. If the Other Area Number field is zero, this field shows the area’s total MW or Mvar exports.
Sched. Flow to Other Area
Scheduled MW transaction from the area specified in the Area Number field to the area specified in the Other Area Number field, and with the Transaction ID given in the Other Area Transaction ID field. The area number field must correspond to a valid non-zero area. If the Other Area Number field is zero, this field shows the area’s total scheduled MW transactions. Delta per Mouse Click can be specified to show a spin button next to this value that can be used for changing it directly from the oneline. Also, you may directly enter a new value in the Field Value field.
Load Schedule Multiplier (MW Only)
Indicates the current value of the MW multiplier applied to the area’s loads.
AGC Status
Displays the AGC status of the area.
Select a Field
Choose from any of the available area fields. Use the Find Field button to open a dialog from which the field can be selected.
Checking the Draw Sparkline checkbox will display a sparkline instead of a field value on the oneline and list only those fields that are available for representation as a sparkline.
Select OK to save changes and close the dialog or Cancel to close dialog without saving your changes.
