Renumber Areas/Zones/Substations Dialog

See Also

 

The Renumber Areas/Zones/Substations Dialog is available while in Edit Mode, by going to the Tools ribbon tab, and choosing Renumber > Renumber Areas/Zones/Substations from the Edit Mode ribbon group.This dialog allows the renumbering of areas, zones, and substations for either the entire power system, and/or for any open oneline diagrams. This dialog is similar to the Renumber Buses Dialog.

This feature is provided because it is sometimes necessary to renumber areas, zones, or substations in the power system model, either to make room for new elements or to move elements to different area, zones, or substations that have a different numbering scheme. It may also be necessary to renumber display objects on the oneline if the oneline is used with a case other than the one for which it was originally designed. The areas/zones/substations renumbering feature provides a convenient way of accomplishing this.

The table at the bottom of the Renumber Areas/Zones/Substations Dialog is used to manage the list of areas, zones, and substations available for renumbering. This list is populated by selecting one of the Automatic Setup of Swap List options. The Automatic Setup options allow the addition of all areas, zones, or substations in the case or only those on the oneline. An option is also available to read the swap information from a file or to setup the swap list based on the current oneline. The Types to Insert option is available for specifying whether or not to add areas, zones, and substations to the swap list. Once the swap list option and types to insert have been selected, click the Setup Swap List to populate the table.

The table behaves just like a Case Information Display and thus has a local menu that can be invoked by clicking the right mouse button. Select one of the Insert options from the local menu to insert a new area, zone, or substation number to change, or select Delete to delete an element number that is currently in the list. The entire list may be cleared by clicking the Clear Swap List button. The Present Number for the element is specified in the list. Change the New Number field to specify the updated number of the area, zone, or substation.

The Renumber Options allows the specification of where the renumbering changes should be implemented. The changes can be applied to the power system case only, the oneline only, or both the case and the oneline.

Once the elements to renumber have been specified and the New Number fields have been set appropriately, implement the changes by pressing the Renumber button. The changes will be applied to the case and/or oneline as specified in the Renumber Options. Close the dialog by pressing Close.
