This section of the Bus Renumbering Dialog is used to generate automatically a list of the buses to be renumbered. Select an option from the list and click on the Setup Bus Swap List button to generate the list, or Clear Bus Swap List to clear the list.
Load All Buses in Cases
Creates entries in the table for every bus in the system. By default the new bus number is the same as the old bus number. Of course you do not have to renumber every bus. If you would like a bus to keep its same number, either add that bus to the table, or simply have an entry with the old and new bus numbers identical.
Load Buses with Valid Area/Zone Filters
Same as the Load All Buses In Case option except only those buses with valid area/zone/owner filters are added. This allows you to easily modify the bus numbers in just an area or zone.
Load Only Buses on Oneline
Creates entries in the table only for those buses on the current oneline. This option is most useful when you are just changing the buses on the onelines.
Load Buses From Text File
Creates entries in the table using an external text file. The format of this file is as follows:
1 11 Specifies converting from old bus number 1 to new bus number 11
2 22 Specifies converting from old bus number 2 to new bus number 22
etc.
Freshen Current Oneline
The Freshen Current Oneline option is designed to help you quickly renumber an existing oneline to work with a new numbering scheme. You will find this method helpful if you have been using the oneline with a case and now must use it with a different case having a different set of bus numbers, but the same bus names. Freshen Current Oneline will try to match the buses on the oneline with the buses in the new case by matching bus names and kV, rather than by number (which is how Simulator usually tries to link bus display objects with bus records in the case). The best way to learn how to use Freshen Current Oneline is to consider the following example:
To update an old oneline to work with a new bus numbering scheme:
- Open the oneline and the old case with which it was used.
- Choose Renumber > Renumber Buses from the Edit Mode ribbon group on the Tools ribbon tab.
- Select Load Only Buses on Oneline and press the Setup Bus Swap List button.
- Change the Swap? field values all to Yes.
- Right click on the table and choose Save List to File. Give the file a name. For this example, we'll name the file "oldscheme.txt." This file will contain the list of buses represented on the oneline, specifying each bus's number, name, kV, and area.
- Close the old case.
- Open the new case and the oneline you wish to renumber. If any other onelines open with the case, close them. You want only the oneline you wish to renumber to be shown.
- Choose Renumber > Renumber Buses from the Edit Mode ribbon group on the Tools ribbon tab.
- Select Freshen Current Oneline and specify the file "oldscheme.txt" (for this example). Click the Setup Bus Swap List button. Simulator will match the old numbering scheme used in the oneline with elements in the new case by name and kV. If it finds more than one match, it will use the element's area name as a tie breaker. If it still can't reconcile the multiple matches, it will add both renumbering options to the table.
- Go through the new list and make sure that you want to swap the buses that are listed. If you do, change the Swap? field value for each to Yes (you can do this quickly for all buses by right-clicking on the Swap? column and choosing Toggle All Yes). Be sure to reconcile any duplicate bus renumbering suggestions. These are cases for which Simulator could not determine how to renumber the buses because a bus on the diagram matches more than one bus in the case by name, kV, and area.
- Click the Change Bus Numbers button at the bottom of the form.
Once the oneline has been renumbered, save it with the case by selecting Save Case (or Save Case As if you wish to give it a different name) from the File menu. See Bus Change Options for additional details.
